How many email users were there in 2020 based on recent business email marketing statistics? A whopping 4.037 billion! And experts predict that this figure will keep growing to reach a staggering 4.481 billion by 2024.

However, spam emails have become quite annoying. Speaking of which, it turns out that the majority of unsolicited spam emails come from the United States and China. 

3. Email stats show that the average consumer has 3 or more email addresses.

And this counts both business and personal email addresses. Adestra recommends monitoring activity to determine whether or not an email address is the primary one. They also stress that acquisition should shift focus to email subscribers instead of looking purely at subscriber email totals. After all, engagement and conversion are all moot points if messages go to a hardly accessed inbox.

4. 93.4% of people between 25–44 prefer email over social media.

According to the email marketing statistics from OptinMonster, the age range of those who are most likely working people prefer to access their emails at 93.4% more than social media, which stands only at 78%.

iPhone ranks second with 15.59% of email opens, then Apple Mail 8 follows with 14.09%. A bit further down the list are Outlook 2013 and Outlook 2010. Marketers can easily tailor the layout and design of their messages to the platforms used by most subscribers with these email marketing statistics

8. The ideal length of a compelling email subject line is 41 characters or less.

It makes perfect sense when you think about it since more people are using smartphones and other mobile devices to access their emails.

Emails statistics say that over time, that could potentially annoy users, especially when other marketers are already optimizing for mobile this way.

9. Marketers write, on average, 434.8 words per email. 

(Source: AWeber)

This number is equivalent to a total reading time of about 3.3 minutes. Over 50% of emails have 300 words or less to avoid overloading subscribers. In email marketing, the overall effectiveness rises with shorter emails. Long-form emails aren’t necessarily bad, though. Just be sure that the topic is interesting enough to hold readers’ attention. Length really depends more on campaign goals. Both short or long emails work for awareness. For increased traffic, short and sweet is the recommended approach.

10. The average ROI for email marketing was $38 for every dollar spent, according to the email marketing data from 2015.

21. Well-written welcome emails can have as high as a 90% open rate, which is almost 4 times higher than the open rate of emails overall.

Advertising statistics show that the first 48 hours after a user subscribes is crucial—it’s when new subscribers are more open to engagement.

Abandonment emails, anniversary emails, and birthday emails fall under this category.

22. Three abandoned cart emails generate 69% more orders than a single email.
