Statistics on Email Marketing ROI

Return on investment (ROI) is a measure of how profitable a campaign is. For email marketing, the ROI may vary depending on the industry, strategy, and business itself. However, these email marketing ROI statistics show a picture of how a maximized email marketing plan can perform.

6. Email marketing has a $36 ROI

Out of all marketing channels, email delivers the biggest bang for the buck. A dollar spent in email marketing generated a $36 return on investment in 2022. This puts email promotions as a low-cost, high-yield marketing channel recommended for even low-budget businesses.

When you consider that many email marketing software platforms offer free plans, the potential ROI for small businesses is even higher. If you’re new to email marketing, we recommend Mailchimp. It’s intuitive and easy to use, and you can send marketing emails completely free until your list size goes over 2,000 contacts.

Average Conversion Rate Stats of Email Marketing

Email stats for conversion rate and other industry standard metrics help determine whether or not an email campaign is performing well. Although there is a wide variety of approaches and strategies to email marketing, it should be able to perform enough to achieve your marketing goals.

11. Email marketing has an average conversion rate of 15.22%

The average conversion rate is 15.22% for email marketing campaigns based on the number of click-throughs. This data was reported by Barilliance, which defined conversions as completed purchases in its study. This type of conversion rate highlights how effective your landing pages are, the strength of your offer, and the appropriateness of your segment audience to your products. Improving these factors will ultimately improve your conversion rate.

12. Email gets you nearly 5x more buyers than social media

Some 60% of customers who purchase products say that they bought because of a marketing email. In contrast, only 12.5% of customers say that they considered clicking the “buy” button on a social media promotion. Email can provide more conversions. In marketing, however, you do not have to choose between one or the other. Social media marketing can still provide valuable leads, engagements, and conversions.

13. ‘Email My Cart’ emails yield the highest conversion rates

The most effective triggered email type by conversion rate is “Email My Cart.” It triggers after a customer has added an item to their cart and then attempts to abandon the session. These customers have added items to their cart, clearly demonstrating purchase intent. The takeaway here for ecommerce businesses is that they maximize the purchase intent of users through email marketing, such as with Email My Cart or Cart Abandonment.

Strategy-related Email Marketing Statistics

Personalization, segmentation, and other email marketing strategies enable marketers to maximize their campaign performance. Deciding which strategies to incorporate into your own campaign can rely on your business type and goals, as well as these email marketing stats that show the effectiveness of specific strategies.

21. Segmentation makes people more likely to click through

Segmenting your email contact list can massively increase open and click-through rates (CTR). One email marketing statistics study found that a segmented email campaign can get open rates as high as 94% and CTR of 38%, compared with a typical unsegmented email campaign (42% open rate and a 4.5% CTR).

The increase in open rate is the most commonly cited reason marketers use segmented email campaigns, with 82% of marketers touting that benefit.

22. Triggered emails perform 3X better than email segmentation/blast

Segmented emails, which are different lists based on different customer attributes, work much better than general email blasts. However, according to research, triggered emails (e.g., welcome, post-sale, cart abandonment, based on website activity, and so on) are three times better and by far the most effective at getting opens and click-throughs.

23. 80% are more likely to buy from a brand that personalizes the experience

Segmenting is the key to personalized experiences, and eight out of 10 consumers are more likely to make a purchase from a brand that personalizes the experience. To make it easier, 83% of consumers also say they’re willing to give you more information so you can create a personalized experience.

24. The ideal email length is 50 to 125 words

Emails with 25 words have response rates of less than 45%, while 25 to 50 words yield over 50% response rates. Fifty- to 125-word emails yield 51% responsiveness, and then rates decline again over 125 words, according to email marketing stats. Noting that the lowest response rates are to the emails with fewer words, it’s important to make sure your email is substantial and reaches at least 50 words.

25. The ideal subject line is 6 to 10 words

Keep subject lines short and sweet! Most mobile devices don’t display many characters, and you want to catch your customers’ attention.

Email marketing statistics show that subject lines between six and 10 words long have an open rate of over 20%, while those with fewer than five words have a 16% open rate. Subject lines with over 10 words will get you an even lower open rate than that. Customer names, song lyrics, or movie titles are good ways to get your customers to click when you don’t have much space.

26. The best emails are simple (3rd-grade reading level)

Emails that have a third-grade reading level have the best response rate—at 53%. This is followed by emails written at a kindergarten reading level, which have a 46% response rate. Email marketing statistics show that high school-level emails get a 45% response, while college-reading-level emails only get a 39% response rate. This implies that the best reception to emails is when the writing is simple and concise and doesn’t have any jargon.

The key takeaway here is that adding a graphic to your email can help it perform better, no matter what measure you’re looking into.

30. Yellow-colored emails get the most opens at 52.80%

An article by Moshe Zviran and his fellow researchers found that color helps create a message context that makes people more inclined to positively respond to an email. This translates to an increase in open rate. Based on the research, a yellow-colored email yields the highest open rate at 52.80%. This is followed by green (52.77%) and blue (51.98%), with the lowest open rate associated with the color pink (50.81%).

In the same study, the standard white email has an open rate of 51.08%. This means that using blue, green, and yellow can help improve emails that aren’t using additional colors yet.

Best Times to Send Marketing Emails

Although businesses have shown massive interest in email marketing tools that help determine optimal send times, it’s still good practice to look into the stats to find the best times for your specific email marketing goals.

32. Friday is the best day for click-throughs

34. 8 a.m.-10 a.m. & 1 p.m.-3 p.m. are the peak times for email opens

Most people open emails in the morning, when they are getting ready to work or in the middle of getting things done, specifically at 10 a.m. Although previous studies showed that emails after business hours were effective (7 p.m. and onward), recent surveys find that these yield the lowest open and engagement rates.

Source: Coschedule

35. Abandoned cart emails are most effective within 20 minutes

Customers abandon online carts all the time—77% of online shoppers who put items in their cart will then click away from the website without checking out. That is a huge loss of sales, and it can mess up your inventory by making stock appear lower than it actually is.

Fortunately, following up by email is highly effective at getting customers to come back and check out their carts. Sending an abandoned cart email within 20 minutes has a 5.2% conversion rate, and that email marketing stat goes down the longer you take to send out your triggered email.

37. The device matters for your subject line

Only the first 30 characters of your subject line are visible on the iPhone email app, so make sure the first 30 characters count. You don’t have to get the whole message across in that short space, but you need to catch their attention so they’ll click on it.

Gone are the days when emojis were considered unprofessional. Nowadays, including emojis in your subject line can increase your open rates by as much as 56%, per email marketing statistics posted by Mailchimp.
