INTRODUCTION
Email marketing is still the leading marketing channel to reach customers, and its effectiveness is only improving. To take advantage of the opportunity of email, marketers need to be focused on the experience they are providing for their subscribers. By understanding, tracking, and improving email engagement, marketers will not only be able to boost their ROI, but it will also help them protect their email program.
Tracking engagement-based metrics (which measure how subscribers interact with your email program) is a critical step in evaluating the success of any email program. Mailbox providers like Microsoft, Gmail, and Yahoo track the positive and negative interactions subscribers have with your program to determine where to place your incoming messages—so marketers need to pay attention to these measures, as well. In fact, a recent study by Demand Metric, in partnership with Return Path, found that marketers who understand that subscriber engagement has a significant impact on filtering decisions are enjoying greater email marketing effectiveness.
While most marketers track metrics like open rates and click-through rates, mailbox providers actually use a different set of data to measure how their users (your subscribers) are interacting with your messages.
The most important engagement metrics for marketers are shown on the right.
These metrics may not be familiar to you, because they typically aren’t included in reporting provided by your email service provider (ESP). Instead, these metrics are measured by mailbox providers—not ESPs—based on all the email they receive and the actions of their mailbox users. Each mailbox provider then uses this data in their own unique filtering calculations to determine where to place incoming messages.
In The Hidden Metrics of Email Deliverability, we detail these “missing metrics” that every marketer should be tracking, what they mean, and why they are important. We also provide industry-specific benchmarks so you can evaluate your email program against your competitors.

Messages marked as spam: A negative signal that email is spam and does not belong in the inbox
Messages read:A positive indicator that subscribers want to receive messages from a particular sender
Messages deleted before reading: A negative indicator that your message wasn’t relevant or desired
Messages replied to: A positive indicator that a message is desired, and likely personal in nature
Messages forwarded:A positive indicator that the recipient desired the message and that others may want it, too
Messages marked as “not spam:”A very strong signal to mailbox providers that email should have been delivered to the inbox

SPAM PLACEMENT RATE
The spam placement rate is calculated as the number of emails delivered to the spam folder out of total emails sent. Your spam placement rate shows the percentage of emails that were identified as unsolicited bulk email, or spam, by the receiving mailbox provider’s spam filtering system.
Factors: The same elements that block you from the inbox will land you in the spam folder. The reasons can be content based (content triggers that flag emails as spam), reputation based (sending patterns and behaviors), or engagement based (subscriber behaviors).
Significance: Spam placement rate is valuable in understanding how mailbox providers and their spam filters classify your emails. A low spam placement rate signifies you’re a trusted sender, and your emails are desired. A sudden increase in spam placement could indicate an issue with a specific campaign, or your entire email program. High spam placement will also impact your other engagement metrics as few subscribers interact with the messages that land in their spam folder. To learn more about what prevents your emails from reaching the inbox, download our Ultimate Guide to Email Deliverability.
Observations: The spam placement average for all industries in 2018 was nine percent. Sectors like distribution and manufacturing (i.e., shipping) and banking and finance saw the lowest rates at four percent. Education/nonprofit/government had the highest spam placement at 19 percent, followed by social and dating at 16 percent.
Year Over Year Change: Overall spam placement saw a large decrease at five percentage points, with the majority of industries experiencing a decrease in their spam placement. Office supplies had the largest decrease at 10 percentage points, followed by food and drug and health and beauty at eight percentage points. Distribution and manufacturing was the only industry to have an increase in spam placement at one percentage point.

READ RATE
The read rate is calculated as the number of emails that are marked as “read” out all emails sent. Read rate is similar to open rate, but it is far more accurate because it accounts for all emails viewed, regardless of image rendering.
Factors: Various factors can have an impact on read rate. The quality of your subject lines and timing typically have the greatest influence, but deliverability issues can also be the culprit behind a sudden decline in emails being read.
Significance: Read rate allows you to distinguish successful campaigns that grab subscribers’ interest, from the failed campaigns that are ignored. Read rate also has an effect on your deliverability, as poor engagement impacts how mailbox providers deliver your email. If your read rates are consistently low, mailbox providers will begin to view your email as unwanted and start delivering your messages to the spam folder.
Observations: Overall, the average read rate in 2018 was 24 percent. Distribution and manufacturing had the highest read rate for the third year in a row at 60 percent. Insurance companies followed in distant second place with a read rate of 43 percent. The education/nonprofit/government and business and marketing industries saw the least positive engagement with subscribers, with read rates of 16 and 17 percent, respectively.
Year Over Year Change: Overall read rates rose in 2018 by two percentage points, with each individual industry seeing an increase as well. Telecommunications saw the highest increase of five percentage points. The rest of the industries had increases between one and four percentage points.

READ RATE BY QUARTER

Another term for this would be the “ignore rate.” As the name indicates, the deleted before reading rate measures how often a recipient deletes email without reading it, calculated as the total number of unread emails deleted out of total emails sent.
Factors: An unread email sent to the trash may signal a disengaged subscriber. A high deleted before reading rate is a sign of a failed campaign. But a consistently high deleted without reading rate can be an indication of permission issues or a lack of satisfaction with your overall email marketing program.
Significance: From a mailbox provider’s perspective, the read rate is an important metric indicating how desirable subscribers find your messages which can impact your inbox deliverability. A high deleted before reading rate, therefore, indicates lack of interest in your messages, and can result in future emails being filtered to the spam folder.
Observations: The average deleted before reading rate in 2018 was 16 percent. Matching its lead in reads, distribution and manufacturing was the least ignored sector with a deleted before reading rate of nine percent. On the opposite end of the spectrum, emails from the pet industry were the most ignored with a deleted before reading rate of 20 percent.
Year Over Year Change: The increase in read rate was accompanied by an increase in actively ignoring emails, as the overall deleted before reading rate rose by four percent. Like reads, each vertical saw an increase in deleted before reading, with pets having the largest increase at six percentage points. The remaining industries had increases between three and five percentage points.

The reply rate is calculated as the number of replies to your email out of the total of email sent.
Factors: A high reply rate could mean one of two things: an engaged subscriber list or subscribers trying to unsubscribe. Truthfully, there’s isn’t a target “reply rate” that your email marketing program should try to achieve. Having a low—or no—reply rate won’t necessarily hurt your deliverability, but having a high reply rate can help.
Significance: A reply to an email message is a very strong positive signal of engagement showing mailbox providers that a message was likely desired, and improves the sender’s chance of being delivered to the inbox for any future campaigns sent to a particular subscriber. We don’t suggest email marketers try anything gimmicky to increase their reply rate. Instead switch from your “noreply@” from: address to one that’s managed.
Observations: Reply rates for commercial emails are unsurprisingly quite low, with an average of 0.06 percent in 2018. Service based sectors saw higher reply rates last year with telecommunications and insurance having the highest reply rates of over one percent. Deals and rewards, education/nonprofit/government, and toys/hobbies/crafts had the least replies at a rate of 0.01 percent.
Year Over Year Change: The overall reply rate decreased by almost half from last year’s average of 0.11 percent. The majority of industries saw a decrease in replies. The largest decrease in replies was in the telecommunication sector with a decrease of more than one full percentage point, but the industry was still able to maintain its lead in reply rates. The pet industry had the only increase in replies at 0.03 percent. Toys/hobbies/crafts and social and dating saw no change in average replies.

Factors: Forwards are generated when subscribers find an email interesting enough that they want to pass it on to others.
Significance: A high forward rate shows strong subscriber engagement and indicates the content you’re sending is relevant to not only your subscribers, but also their networks.
Observations: Like replies, forwards are rare for commercial emails with account based sectors seeing higher rates. The overall average for forwards in 2018 was 0.02 percent. Along with their high reply rates, telecommunications and insurance along with distribution and manufacturing had the highest forward rates at 0.13 percent. Deals and rewards and social and dating had the lowest with an average of zero forwards.
Year Over Year Change: The overall average forward rate saw no change from last year, and the majority of verticals also saw no change. Along with its increase in replies, the pet industry had the only increase in forwards at 0.01 percentage points. Insurance had the largest decrease in forwards at 0.04 percentage points.
The forward rate is calculated as the number of your emails that are forwarded on to others out of total emails sent.

Factors: There are various reasons why a subscriber would mark your messages as spam throughout the different stages of an email relationship. For more information about why complaints occur, download the Marketer’s Guide to Subscriber Complaints.
Significance: Spam complaints are a direct signal from subscribers to mailbox providers that your content is unwanted. As such, mailbox providers heavily factor spam complaints into their filtering decisions.
Observations: The average overall complaint rate in 2018 was 0.39 percent, well over mailbox providers’ recommendation of 0.2 percent. Business and marketing had the most complaints with an average of 1.4 percent, followed by jobs and office supplies at 0.77 and 0.73 percent, respectively. General merchandise, distribution and manufacturing, and toys/hobbies/crafts where the only industries that achieved averages below the recommended 0.2 percent.
Year Over Year Change: Complaints more than doubled from last year’s average of 0.17 percent. The majority of industries had a rise in complaints, with business and marketing having the largest increase at 0.98 percentage points. The office supply industry was the only vertical to see a decrease in complaints from last year, although it was slight at just 0.03 percentage points.
The complaint rate is the rate at which subscribers report your messages as spam. It is calculated as the number of “report spam/junk” complaints out of emails sent.

Factors: There are a number of reasons for a low “this is not spam” rate. Only email that lands in the spam folder can generate a “this not spam” vote; therefore, a low “this is not spam” rate may not be a problem at all and could indicate that few of your emails are being sent to the spam folder. But if you have a high percentage of mail being sent to spam and your “this is not spam” rate is still low, the causes could be a lack of permission, lack of awareness, or simply a lack of interest from your subscribers.
Significance: The “this is not spam” metric is a strong and positive indicator to mailbox providers that your emails are desired and may indicate a false positive with the spam filter. A “this is not spam” selection shows mailbox providers that subscribers are actively searching for your messages, enough to go into the spam folder and “rescue” them.
Observations: The overall “this is not spam” rate for 2018 was 0.02 percent. Distribution and manufacturing and telecommunications were rescued from the spam folder the most at 0.08 and 0.05 percent, respectively. Education/nonprofit/government, kids and babies, and real estate saw the least rescues with a “this is not spam” rates of 0.01 percent.
Year Over Year Change: 2018 saw a steep drop in “this is not spam” rescues at 1.75 percentage points. This might largely be a result of the decreased overall spam placement, which was five percentage points lower than the previous year’s results. Every vertical saw a decrease in “this is not spam” rates with general merchandise seeing the largest decrease of 3.17 percentage points, followed by flowers and gifts at 2.59 percentage points.
The “this is not spam” rate is calculated as the number of times a subscriber marks your message “not spam” or “not junk” out of the number of emails delivered to the spam folder. Another term for this would be the rescue rate as these messages are rescued from the spam folder by subscribers.

KEY TAKEAWAYS
Marketers were more successful at reaching the inbox in 2018, with overall spam placement decreasing by five percentage points. One large contributor to this is likely the new data protection laws that were put into effect (GDPR). This new standard requires marketers to clean up their lists to send only to subscribers they have clear permission to mail to. While this led many marketers to remove large portions of their list, the upside is a clearer, more active subscriber file to market to.
An offshoot of these cleaner lists is a more active list; however, this increase in engagement was both positive and negative in nature. While overall read rates rose by two percentage points and all industries saw increases of various sizes, deleted before reading and complaint rates also increased.
As subscribers increase their activity in the inbox, is more important than ever for marketers to pay attention to subscriber activity. To take advantage of this, marketers should try the following tactics:
Keep track of your metricsTrack how your subscribers interact with
each message and adjust your content accordingly. Are they complaining
more for certain campaigns, or when you increase send frequency? Are your
subject lines enticing subscribers to open or are they actively placing your content in the trash? In a recent study
we found that on average, marketers lose 34 percent of new subscribers within
the first month of their subscription. By keeping a close eye on subscriber activity,
marketers can identify early signs of disengagement and work towards re-engaging these valuable subscribers.
Segment your lists to more effectively engage your subscribers Take full advantage of your engagement
data to build segments. By analyzing how subscribers interact with each
campaign, you can identify their preferences and group them together
with those who took similar actions. By breaking your list into segments you can build more targeted content and provide
a more personalized experience for your subscribers—and hopefully boost
engagement and ROI.
Don’t wait till subscriber disengages to try to win them back
In our recent study on the subscriber lifecycle, we found that the average
marketer continues sending mail for a full 259 days after a subscriber last engages with their program. Rather than waiting
eight months, try sending a winback campaign or some other enticement
to re-engage while subscribers can still remember why they enjoyed your email
program. In fact, winback emails have an average read rate of 20 percent, which
means you can potentially reactivate one out of every five disengaged subscribers.

METHODOLOGY
Return Path conducted this study using global consumer data consisting of over 17,000 commercial senders, 2 million consumer panelists, and over 6.9 billion commercial email messages sent to Microsoft, Gmail, Yahoo, and AOL users between January 1, 2018, and December 31, 2018.
Consumer data is information captured from monitored email accounts controlled by real subscribers to sample user initiated and engagement based filtering decisions by mailbox providers. Consumer data can uncover behavior based factors and thresholds that influence inbox placement at large mailbox providers, and can’t be identified by non-interactive seeds.
Percentages may not total 100 due to rounding.

Email remains one of the most important marketing channels. Recent Demand Metric studies confirm that it is one of the most-used channels, and that it ranks high on the list of best ways to reach certain groups, such as sales and marketing and technical audiences. Significant vari-ance, however, exists in the results marketers get from using email.
Demand Metric and Return Path by Validity continue to partner to under-stand which email tactics marketers are using, how well they are working, and what challenges prevent greater success with email.
The most recent edition of this research continues to pursue answers to the key question:

Executive Summary
2019THE STATE OF EMAIL MARKETING
THE STATE OF EMAIL MARKETING 2019 7EXECUTIVE SUMMARY
The top email marketing objectives are communicating with customers (74 percent), building brand awareness (64 percent), and communicating with prospects (63 percent).
Over one-third of study participants (37 percent) report that email marketing effectiveness is increasing, down from 44 percent in 2018.
Firms that report increasing email marketing effectiveness are more likely to also report annual revenue growth.
The biggest email marketing challenge is competition for attention in the inbox (45 percent).
Email deliverability ranked third on the list of challenges and saw a 12 percent increase compared to the 2018 study.
Email personalization was the top email marketing tactic in use (72 percent), a slight increase from the 2018 study.
One-third of study participants have no formal subject-line optimization process.
This report shares the results of the 2019 research study, providing insights and data useful for benchmarking, planning, and improving email marketing effectiveness.

The objectives in place for email marketing show subtle changes from 2018 to 2019, as Figure 1 summarizes.
The top three objectives are unchanged from last year, but in a different rank order:
Communicate with customers
Build brand awareness
Communicate with prospects
These top objectives parallel the overall marketing mission. The 2019 results don’t show a significant shift in objectives, but perhaps reflect a more pragmatic orientation through the increase in the revenue generation objective.

EMAIL MARKETING OBJECTIVES
Experienced marketers understand that ensuring email effectiveness requires constant vigilance and maintenance. Many, dynamic factors influence email marketing success.
The implication is that rarely is its effectiveness holding steady: for most marketers it is either improving or declining. Study participants share in Figure 3 how they rate the effectiveness of email as a marketing channel.
The effectiveness of email as a marketing channel did not show improve-ment year-to-year in this study. This lack of increased effectiveness, however, did not apply equally to all study participants.

EMAIL MARKETING OBJECTIVES
This email marketing effectiveness data lets us segment objectives by effectiveness. This segmentation was presented in the 2018 report, and Figure 4 presents it using the 2019 data.
In all cases, a much higher percentage of organizations that report increasing email effectiveness cite having the email objectives listed in Figure 1.
In fact, the difference between the effectiveness segments for these email objectives averages 18 percent, with the greatest delta resulting from the “Generate revenue” email objective.
In the 2018 study, the average difference between these segments was only 10 percent. This study did not look for the reasons why firms that report increasing email effectiveness have loftier objectives for email than those that report declining effectiveness.
But we can speculate; where email effectiveness is on the rise, it’s likely the result of an investment in time, tools, or acquiring skills to use email effectively.

When analyzing this email effectiveness data, an interesting relation-ship came to light between revenue growth and email effectiveness.
Study participants were asked to characterize their organization’s revenue growth during the most recently completed fiscal year, using the following categories:
Figure 5 displays this relationship between revenue growth and email marketing effectiveness.
There are certain cautions to note when looking at correlations in data. Statisticians and marketing research analysts are always quick to point out that “correlation is not causation” and that adage applies here. It is an oversimplification to imply that investing to increase email marketing effectiveness guarantees revenue growth.
Managing an effective email marketing program isn’t a guaranteed cure for all revenue ills, but this data shows it clearly can serve as a component in driving growth. This relationship between email marketing effective-ness and revenue growth should cause marketers to sit up and take notice. Their efforts to curate an effective email marketing program can play a key role in driving revenue growth.

The study inventoried the challenges of marketing through the email channel, as Figure 6 summarizes.
Email Marketing Challenges
The top challenge for 2019 remains the same, although at a lower severity than in 2018. Deliverability, however, has surged as a problem, up 12 percent year-over-year.
A new challenge appears as a response option in the 2019 survey: “Lack of tools to optimize or personalize email,” and it ranks fourth in the 2019 list of challenges.
The “Other challenge” response option elicited some insightful write-in comments, which we summarize here:
Lack of engagement, list growth, data quality, email copywriting, technology stack limitations, internal silos.

While some debate may exist about the quality of open rate as a metric, the reality is that no other actions can occur that matter to email marketers unless emails are opened.
Figure 7 compares open rates from the 2018 study with 2019 study data.
The greatest change in the 2019 study comes in the middle of the range shown in Figure 7. In 2018, 39 percent of participants reported open rates between 11 and 20 percent.
In 2019 that figure is 46 percent, and the increase comes from both ends of the range: fewer participants reported open rates of 5 percent or less, and fewer also reported open rates of more than 21 percent.
FIGURE 7
The average email open rate for the 2019 study skews higher than in 2018.

Open rates correlate to email marketing effectiveness, and Figure 8 shows how strong the relationship is between reported effectiveness and open rates.
The relationship between open rates and email marketing effectiveness is intuitive, and Figure 8 shows exactly what logic suggests we should see. Seeing the actual comparison numbers, however, is impactful.
Over half of participants whose email marketing effectiveness is increasing enjoy open rates of 16 percent or more. Barely one-third of those whose email marketing effectiveness is decreasing report the same open rates.
Investing to increase email marketing effectiveness will pay dividends in higher open rates.

Open rates showed a correlation to the type of firm that was using email for marketing. Figure 9 shows this relationship.
B2B and B2C firms have a greater struggle with open rates than do the Non-profit organizations in the study. Using an average open rate of 15 percent or less, the differences are evident:

The objective of an email send may influence the open rate for those sends. The data about open rates and email marketing objectives results in the graph shown in Figure 10.
Figure 10 should encourage marketers to employ less subtlety in crafting their marketing email messages.
This study’s data shows that when generating revenue is one of the objectives for email marketing, the average open rates are better.
When the objective is communicating with prospects, average open rates are the worst. While just speculation, the absence of a relationship between sender and receiver may underpin the reason for the latter.

As was the case in 2018, staffing and resource constraints pose a chal-lenge to email marketing success. Figure 11 shows a summary of the resources study participants use to support their email marketing efforts.
Firms in the 2019 study showed a marked increase in using outside resources and expertise, either through outsourcing or through blending resources with in-house email marketing efforts.
The resource mix for email marketing showed some major differences based on the B2B or B2C orientation of the firm:
FIGURE 11

B2C firms are more willing to invest in outside resources to help with their email marketing efforts.
Looking at the use of resources from Figure 9, using the average open rates in Figure 7 revealed no significant difference in which resources were in use. In other words, lower open rates were not associated with heavier reliance on one type of resource over another.
The resource use mix was virtually identical for open rates of 15 percent and below, and for 16 percent and above. Clearly, concerning open rates, other disciplines and best practices come into play.
THE STATE OF EMAIL MARKETING 2019 21EMAIL MARKETING CHALLENGES
Third on the list of challenges in this year’s study was email deliverability. Over one-third of the study participants have this challenge, compared to just one-fourth in 2018.
A way that some organizations attempt to address this challenge is by changing their email service provider (ESP) or adding a new, dedi-cated IP address. Figure 12 shows the frequency that study participants resorted to this remedy.
In the 2018 study, the survey simply asked participants a “yes” or “no” question about making a change to their ESP or IP. The 2019 survey made this question more granular to identify the specific type of change.
A comparison is still possible: in 2018, 57 percent changed neither, 24 percent made one or both changes, and 19 percent didn’t know.
The increase in the email deliverability challenge in this year’s study corresponds to an increase in making ESP, IP, or both changes in an effort to deal with this challenge.

Perhaps the most important question to answer regarding changing the ESP, IP, or both is, does this strategy work? Figure 14 shows the relation-ship between these changes and average open rates, which correlated in this study.
Figure 14 suggests that changing ESPs or dedicated IP addresses is a bad idea: the firms in this study that did experienced noticeably lower average email open rates.
However, when considering these results, readers should understand that:
Poor results are a leading cause of making a change in the first place.
The benefits of making a change are not immediately realized.

In the pursuit of increased email marketing effectiveness, marketers use a number of tactics. This study continues to measure the use of known email marketing tactics, and results from this year and the 2018 survey are shown in Figure 15.

The order of the three most popular tactics remains unchanged year-to-year, while the usage percentage shows slight changes. The big changes from last year come in greater adoption of email deliverability optimi-zation and A/B testing.
THE STATE OF EMAIL MARKETING 2019 26EMAIL MARKETING TACTICS & TECHNOLOGY
Of tremendous interest are the tactics in use by those in the study who enjoy the highest, average open rates for their bulk email sends. Figure 16 shows this view.
It seems obvious that those who enjoy higher average open rates are getting them because they use tactics that boost those rates.
FIGURE 16
Almost every tactic sees greater use by those with higher, average open rates.

Email marketers with higher average open rates are doing something different to get those opens, and Figure 16 provides insight into what they are doing differently.
THE STATE OF EMAIL MARKETING 2019 27EMAIL MARKETING TACTICS & TECHNOLOGY
A top tactic in both years of this study was email list management. Figure 17 shows some of the actions study participants take to manage their email lists.
FIGURE 17
Little change is seen year-to-year in list management actions.

The one area of noticeable change, and a very healthy one, is lower use of purchasing email addresses as a list management action. Email marketing pundits agree that the risks from adding purchased email addresses to lists far outweigh the benefits.

Another top email marketing tactic in both years of this study is subject line optimization. Various levels of formality around this process exist, which are summarized in Figure 19.

Open rates will again serve as a filter to understand the potential impact of subject line optimization practices on open rates. Figure 20 compares low and high average open rates segments in the study.

What Figure 20 makes obvious is that having a formal optimization process helps boost average email open rates, and that simply looking at past campaign performance does much to drive open rates in the right direction.
These relatively simple differences in behavior separate the segment with lower average open rates from the segment that enjoys higher rates.

Sender Score is a measure of reputation for email marketers. It ranges from zero to 100, with higher scores related to better email deliverability. In 2018, just 19 percent of firms in the study were using technology such as Sender Score to determine how mailbox providers rated them. This year, the figure jumps to 45 percent.
Average Sender Score ratings are shown in Figure 22, segmented by high and low average email open rates.
Consistent with other segmentations of this study’s data around average email open rates, the expected outcome appears in Figure 22. The prac-tices that lead to higher Sender Scores have their desired result: higher average email open rates.

Blacklist technology is yet another tool available to marketers to help them continuously monitor the IP addresses associated with their email sends. This technology alerts users if a monitored IP address lands on a blacklist, enabling taking action to remedy this problem.
Almost half (46 percent) of the study’s participants say they are using blacklist technology, a 19 percent increase over reported 2018 usage.
As Figure 23 shows, those who use this technology are more likely to enjoy higher average open rates for their bulk email sends.
The reason blacklist technology helps drive average email open rates higher is because it addresses the deliverability issue. Many emails sent from blacklisted IP addresses may never hit the recipients’ inbox, and therefore are never opened.
Using this technology helps ensure emails land in inboxes, where opening them becomes a possibility.

Better than avoiding having an IP address blacklisted is working to have your company appear on certified whitelists. Less than 30 percent of organizations in this study know if they are on a certified whitelist, roughly the same level reported in the 2018 study.
Figure 24 compares high and low average email open rates for appearing on certified whitelists.
To appear on a certified whitelist is a very good thing for an email marketer. However, this data suggests that it is more important to not be identi-fied as a bad email actor than it is to gain recognition for being a good email citizen by virtue of appearing on a certified whitelist.
Supporting this premise is the fact that over two-thirds of study partici-pants have not taken any email training or certification.

It’s possible for email marketers to know a great deal about their subscribers if they choose to exploit the data that is at their disposal. Figure 25 summarizes what study participants say they know about major subscriber preferences.
The year-to-year differences for known subscriber preferences are negli-gible. Comparing the high and low average email open rate segments reveals two preferences with noticeable differences:

The delta for these two preferences is not coincidental. Time spent reading email is one of the best engagement indicators.
Furthermore, other studies report that most email is now read on a mobile device, and it stands to reason that marketers should want to understand which devices their subscribers use to enable message optimization.

EMAIL MARKETING SUBSCRIBERS
Marketers that wish to create a great customer experience must focus on every single touchpoint that customers have with brands, and that includes email.
Just over 70 percent of study participants use technology to preview email campaign sends across various devices and clients before sending, a slight increase from 2018.
Figure 26 displays the differences between average email open segments.
Generating previews is yet another example from this study of tech-nology that is available to help email marketers improve campaigns. Plenty of technology advantages are available to marketers who choose to use them.
A comprehensive email marketing plan includes having more advanced intelligence about the subscriber base:
Which competing brands are also emailing subscribers
Which days of the week are busiest for subscribers
What competitor email campaign metrics are
Over half (53 percent) of the participants in this year’s study have no visi-bility into these items, down from two-thirds in 2018.

EMAIL MARKETING SUBSCRIBERS
Monitoring competitor email activity is an in-depth aspect of monitors that, in 2018, 57 percent of study participants failed to do.
The percentage is lower in the current survey year, with barely half who monitor competitor email activity. There are several forms that such monitoring might take:
Subscribe to their lists using an alias
Subscribe to their lists under a true identity
Use 3rd party software or technology to monitor
Monitor through cooperative partners or customers
Figure 27 shows the difference in average email open rates based on competitor monitoring.
Assuming that marketers exploit the insights that come from monitoring competitor activity, doing so appears to impact average open rates.

THE STATE OF EMAIL MARKETING 2019 40EXECUTIVE SUMMARY
It’s possible for email marketers to know a great deal about their subscribers if they choose to.
As this and many of the graphs in this report show, many factors influ-ence average email open rates. Open rates are an important metric because the actions that marketers hope for from a bulk email send require that recipients open messages.
However, the act of opening an email isn’t the end game–a conversion is, and that conversion is quite often a click.
A strong correlation exists between open and click rates, and Figure 28 shows this relationship using the now familiar high and low average email open rates.
The relationship between open and click rates is not as intuitive as some may conclude. A message with a compelling subject line, sent from a company on a certified whitelist, may fail to generate clicks due to poorly written email body copy.
Conversely, a brilliant email message is easily foiled through a bad subject line or failure to test.
This relationship between open and click rates suggests, more than anything, that marketers that follow best practices to ensure email opens apply that same level of care to crafting messages that generate conversions.

One final correlation will bring this report to a conclusion. The pres-ence of an organization on a certified whitelist (Figure 24) correlates to revenue growth. Figure 29 summarizes this relationship.
What the data from Figure 29 affirms is that where email marketing is concerned, an ounce of prevention is worth a pound of cure.
The characteristics of organizations that are intentional about ensuring that their email marketing practices earn them a place on a certified whitelist are the same characteristics that lead to revenue growth.
Perhaps this is obvious, much like saying that a person who goes to the gym regularly is in better physical shape. But the relationship between email marketing and revenue growth (Figure 5) emerged in the 2018 study, and appears again in this year’s study.

THE STATE OF EMAIL MARKETING 2019 43EXECUTIVE SUMMARY
Marketers should strive to achieve high levels of email marketing effectiveness.
The cost of email is low relative to other channels, and when compared to the potential return on email marketing, the ROIs are often high.
Despite the volume of data this report shares, the email marketing strategy is simple:
Analyst Bottom Line
1 Ensure that emails have the highest possible inbox placement rate
2 Craft subject lines and use tactics that generate the highest possible open rate
3 Construct messages and use tactics that generate as many clicks (conversions) as possible
THE STATE OF EMAIL MARKETING 2019 44EXECUTIVE SUMMARY
Set bold objectives.
Like any initiative, email marketing needs direction. Setting bold objectives for an email marketing program helps drive the action and attention to detail that lead to greater effectiveness.
In this study, participants with the highest average email open rates were more likely to have revenue generation as one of their email objectives.
1 Maintain your list.
It’s far too easy to forget about maintaining your subscriber list, but failing to do so steadily erodes open rates.
This study shows that honoring “opt out” requests, adding new email addresses organically, and removing bounced email addresses are the maintenance actions that have the greatest influence on open rates.
3
Use the right tactics.
Figure 16 lists a number of email tactics, and the use of any of them is associated with higher average open rates. Specifically, email deliverability optimization, A/B testing, and reactivation campaigns were particularly strong at driving more opens.
2 Optimize your subject lines.
Perhaps no other aspect of an email message has more to do with generating an open than the subject line. Yet, creating a subject line is often a last-minute task to which little thought is given.
Where subject lines are concerned, simply looking at past campaign performance and learning from it was the single practice having the biggest impact on open rates.
4
Recommendations
A number of recommendations come out of this study to help marketers execute this strategy at the highest level of effectiveness:
THE STATE OF EMAIL MARKETING 2019 45RECOMMENDATIONS
What’s important for marketers to understand about achieving greater email marketing effectiveness is that the study identifies no single “game changing” practice that yields exponentially better results.
Instead, it is through the adoption of all the recommended practices and technologies that in aggregate will help marketers attain the highest possible performance from their email marketing efforts.
Leverage technology.
This study references a number of technologies, and the use of any of them – inbox placement, Sender Score, blacklist, preview, and certified whitelist technology – relate to higher average open rates.
5
Know your subscribers.
Failing to learn subscriber preferences compromises the effectiveness of email marketing efforts. The study found that two preferences in particular relate to higher average open rates: knowing how long subscribers spend reading emails, and knowing which mobile device subscribers use to read emails.
6
Know your competitors.
The study shows that monitoring competitor email activity, either as a subscriber or using third-party technology, relates to higher average open rates.

INTRODUCTION
Reaching the inbox is always a challenge. While marketers might feel that mailbox providers are being unreasonably strict, there is a reason for this. There is a lot of bad email being sent. Last year alone saw over 600 billion emails from spammers.
Mailbox providers have these strict protocols in place not to block legitimate senders, but to keep spammers and harmful content out of their users’ inboxes. To identify the “good” from the “bad,” mailbox providers judge an incoming sender’s reputation when determining what email to allow or block from their inboxes. A sender’s reputation is calculated using a variety of metrics, and each mailbox provider has its own formula to judge whether or not to accept incoming mail and where to filter it.
Marketers who are aiming for the inbox use Return Path’s Sender Score to discover and track their sender reputation and learn how mailbox providers perceive their messages. Similar to a credit score, Sender Score is an evaluation of your sending practices compared to other senders to determine the quality of your messages and your email program. A marketer’s Sender Score is expressed as a number between 0 and 100. Sender Score uses data points and reputation formulas similar to what mailbox providers use to give a relatively accurate representation of how mailbox providers view your email.
In this report, we will discuss some of the factors that go into both Sender Score and mailbox providers’ reputation calculations. In addition, we’ll take a look at the impact these elements on your sending reputation, and how your reputation affects your deliverability.
To get the most out of this report, look up your Sender Score and use it to understand how mailbox providers are viewing your program.

THE STATE OF EMAIL REPUTATION
The quality of email programs has improved dramatically since our first Sender Score Benchmark in 2012 when botnets ruled and spammed the world. At that time, a staggering 60 percent of messages sent came from IP addresses with a Sender Score below 11. Today, only 16 percent of email scored below 11. While the drop in spam over the last eight years can mostly be attributed to the takedown of botnets, email marketers are also more aware of reputational risks and have more tools and solutions at their disposal to monitor and solve reputation issues.

METRICS THAT INFLUENCE SENDER REPUTATION
While each mailbox provider has its own formula which assigns different weights and values to various components of sender reputation, the factors they include are generally the same. Three key metrics that factor into sender reputation are complaint rate, unknown user rate, and spam trap count.
These metrics are included in reputation calculations because they provide insight into a sender’s mailing practices. Those with low complaint and unknown rates and few spam trap hits are seen as reputable senders and receive a higher reputation score. As a result, inbox placement tends to be higher for these senders.
COMPLAINTS
A complaint is generated when a mailbox user marks a message as junk or spam. A high complaint rate signals to mailbox providers that users perceive the message as spam or abuse, and helps the mailbox provider to automatically detect similar spam or abuse messages in the future.
Senders with a Sender Score above 90 were the only ones who managed to maintain a complaint rate below one percent. Those with a Sender Score between zero to 90 had a sharp increase in average complaint rate, ranging from 4.6 percent to 6.3 percent.
Average complaint rates more than doubled from last year for senders scoring between 11 and 100. Complaints can originate from various sources for a variety of reasons.

where complaints are coming from and why.

UNKNOWN USERS
An unknown user is a type of bounced message indicating that an email address doesn’t exist at the receiving mailbox provider. Mailbox providers return a hard bounce code (5xx) indicating when email is sent to an unknown user. Senders who not only retain unknown users but send to a high percentage of them are perceived by mailbox providers as suspicious or having poor list hygiene practices. A high unknown user rate can cause your messages to be throttled, delivered to the spam folder, or blocked.
Senders with Sender Scores above 90 tend to keep relatively clean lists, with average unknown user rates of one percent. The next highest band (81-90) saw an average of three percent, with the rest (zero-80) maintaining an average between six and eight percent.
In most cases, marketers should immediately remove addresses that return a 5xx hard bounce code. To learn about the different types of bounces and how
to process them, read the Email Marketer’s Guide to Bounce Processing.

SPAM TRAPS
Spam traps are decoy email addresses used to identify spammers. There are two types of spam traps:
• Pristine spam traps are decoy accounts that aren’t owned by a real person and therefore never subscribe to mailing lists. Mail received at these accounts indicates the email address was acquired without permission, and may also indicate it was acquired through illegal methods such as harvesting.
• Recycled traps are addresses that were once held by a user, but have been abandoned and converted into spam traps.
Senders with a Sender Score above 90 were the most successful at keeping their lists clean with an average of 0.41 spam traps. Senders scoring 50 and below saw an average of around one or more spam trap hits, with those scoring below 11 seeing an average of 3.09 spam traps.

A sender’s delivered rate measures the percentage of messages that aren’t bounced or rejected by mailbox providers’ gateway filters. The delivered rate does not show which folder the messages were then delivered to—primarily the inbox or the spam folder—but it does factor out any messages that have no hope of being seen by subscribers.
In 2018, senders scoring above 90 had an average delivered rate of 91 percent. Those who fell one band below (81-90) saw less mail delivered, with an average of 71 percent. The remaining senders—those scoring between zero and 80—saw more than half of their messages rejected at the gateway. Those scoring above 60 also saw a slight year-over-year increase in delivered rates.

After passing the gateway (the delivered rate shown on the previous page), emails are then subjected to additional filters. These filters—including both reputation-based filtering and engagement-based filtering—determine which folder each message is finally delivered to.
As discussed previously, each mailbox provider has its own unique formula for evaluating reputation. Although, the factors that weigh into this analysis are generally the same. As a result of the different formulas, senders may experience different inbox placement rates at different mailbox providers.
In the graph on the right, you can see the impact these different filtering formulas have on inbox placement rates at Gmail, Microsoft, Yahoo, and AOL. It’s worth noting that each mailbox provider’s inbox acceptance generally increases with a higher Sender Score and better sending practices.

Microsoft remained the hardest mailbox to reach in 2018 with even the best senders only reaching the inbox 72 percent of the time. Senders did see a slight increase in deliverability compared to the previous year with most bands seeing an increase in inbox placement rates.
Senders saw slightly higher inbox placement at Gmail, with the top senders managing an average inbox placement rate of 88 percent. Senders were more successful in reaching Gmail inboxes compared to the previous year, with increases ranging from seven to 27 percentage points.
At Yahoo, the top senders had an average inbox placement rate of 88 percent. However, most senders found reaching Yahoo inboxes harder compared to the prior year with decreases ranging between one and five percentage points.
AOL remained the easiest mailbox provider to reach, with the best senders achieving an average of 93 percent inbox placement--although deliverability at AOL changed dramatically year over the year. AOL, which was acquired by Verizon Media Group, migrated its email filtering to Yahoo (also owned by Verizon Media Group) over the summer and fall of 2018. With a new filtering system in place, inbox placement rates at AOL decreased by four to 56 percentage points.
The chart on the right shows that sender reputation filtering is still important in spam filtering algorithms. However, a high Sender Score on its own doesn’t translate to higher inbox placement rates. Subscriber engagement, a mailbox provider’s own reputation calculations, and the content in the incoming message—none of which are included in Sender Score calculations—all factor into each mailbox provider’s final filtering determinations.

To help marketers evaluate their own email program against their peers, we dug into Sender Score performance by industry. The chart on this page shows the average Sender Score and inbox placement rate for more than 17,000 commercial senders, broken out by industry. As only legitimate commercial senders are included, these numbers provide a relatively accurate reflection of how each industry is performing.
In 2018, most industries had average Sender Scores above 90, with deals and rewards, insurance, and pets achieving the highest average at 96. Telecommunication companies struggled with reputation, posting the lowest average Sender Score at 76.
Most industries saw either no change or a slight increase in average Sender Score year over year. Health & beauty, telecommunication, and toys/hobbies/gifts were the only industries to have a decline in Sender Score, with telecommunications seeing the greatest decrease of six points.

As you can see, your reputation is a strong factor in your ability to reach the inbox. However, many elements can cause your reputation, and (as a result) your deliverability, to decline.
To build and maintain a strong reputation, focus on the following:
Keep your list clean The quality of your list is a big factor for your reputation. Make sure you are routinely checking your list for unengaged users who may be spam traps in disguise. Run your list through a list validation service to make sure all your emails are owned by real people and check every new email you add to your list.
Know all the blacklists and make sure you are not listed Blacklisting is another factor to mailbox providers filtering formulas and each mailbox provider uses different ones to different degrees. Make sure you know which blacklists are available and how to get delisted. And routinely check that your IP address is not listed anywhere.
Sign up for feedback loops Feedback loops help marketers identify when subscribers complain about their messages, allowing them to resolve the complaint and avoid future ones from the same user. Most mailbox providers offer their own feedback loop services. You can learn more about the different types of feedback loops and how to set them up here.
Check Sender Score Before you send a campaign, check your Sender Score. Your Sender Score can fluctuate based on the results of your recent activity. Rather than find out after you send your campaign that you have a problem, check your latest reputation score and resolve any issues. Once your Sender Score has improved, your messages are more likely to reach subscribers.
