Email Usage Statistics

1. More than 4.3 billion people use email, which is set to grow to 4.6 billion users in 2025.

Indicating that the business needs to define an email marketing strategy because the opportunity is still here.

2. 99% of email users check their inbox every day, some as much as 20 times a day

(OptinMonster, HubSpot)

Of which 58% check their inbox first thing in the morning. In comparison, only 14% open a social media platform for the first check of the day.

Moreover, consumers also check their inboxes as a complementary activity; almost 69% check their inbox while watching TV. Additionally, 79% of people check their emails even when they are on vacation.

Still, as much as 40% of email users say they have at least 50 unread emails in their inboxes.

3. 59% of Millennials and 67% of Gen-Zers primarily use their mobile to read and send emails

5. An average American spends almost 5 hours checking and responding to emails daily.

(Adobe)

Yet, inexplicably, most people say their frequency of checking email is “just right.”

Back in 2021, an individual spent 3+ hours (209 minutes) checking inboxes and responding on a given weekday, which is less than 256 minutes back in 2016.

Furthermore, an average American spends 2+ hours (143 minutes) daily checking inboxes and responding to personal emails. This, too, is decreasing YoY. Back in 2016, people spent 156 minutes on average checking personal emails.

Nevertheless, Adobe’s recent email marketing stats indicate that Millennials are protecting their time spent on checking emails for other personal pursuits.

As of 2019, 50% of Millennials say they wait until they get to work to review work emails.

(eMarketer)

Organic search (62% of professionals say), paid search (59%), social media (51%), retargeting (49%), referral marketing (21%), mobile marketing (16%) — all the other digital tactics for acquiring customers and increasing retention were chosen by fewer respondents.

Furthermore, Campaign Monitor’s recent email marketing statistics indicate that as much as 41% of marketers say email marketing is very critical for the company’s overall success. 90% say e-mail marketing is somewhat crucial for the organization’s overall success.

14. Although it’s not a competition, email marketing conversion rates are 3x more than social media conversion rates.

(OptinMonster)

Content marketers say a reasonable conversion rate is between 2% and 5%.

Guess what?

The average email conversion rate is 6.05%, a point higher than what is considered good. On the other hand, the social media conversion rate is just 1.9% (3x less than email).

Even the average engagement rate for email marketing is higher (open rate — 22.86%, CTR — 2.33%) than the social media engagement rate (0.58%).

Moreover, over 60% of users say they have purchased a product or service because of the marketing emails. In comparison, only 12.5% have purchased using the buy button on social media platforms.

However, marketers use email marketing and social media for different reasons. So, it is not a competition.

For instance, email marketing allows marketers to deliver personalized messages to customers. Most marketers use email campaign tactics to build relationships with customers — explaining why most people purchase a product after receiving marketing emails.

Whereas marketers mainly use social platforms to drive website traffic, build a community, and build brand loyalty. That is to say, don’t treat email marketing as a replacement for social media.

Mobile Email Marketing Statistics

15. Apple Mail on the iPhone is the most popular email client with a market share of 38.2%, followed closely by Gmail.

(Litmus, August 2021)

Apple Mail on Mac (10.4%), Outlook (6.0%), Yahoo! Mail (4.3%) are the other popular email clients worldwide.

Clearly, it means that most users access emails on a mobile device, the stats suggest the same.

• 41.6% use a mobile device to check their inbox and respond to messages.

In the most popular webmail opens category: 86.3% use webmail to access Gmail. 10.5% access Yahoo! Mail.

Nevertheless, 75.55% of all marketing emails are opened on desktop or webmail. In fact, only 25.45% open marketing email on mobile devices.

However, when it comes to marketing emails CTR, the margin between mobile devices (45.10%) and webmail or desktop (54.90%) is pretty tight.

Meaning when planning to send a marketing email to the users, ensure to optimize it for mobile devices.

16. Nearly 1 in 5 emails are not optimized for mobile devices.

As mentioned earlier, 41.6% use a smartphone to check their inbox, which is based on American respondents (nearly 65% of their data comes from the United States).

Nevertheless, almost all the email marketing stats on the internet (global respondents) indicate that the percentage of emails opened on mobile is at least 50%. And that sound’s right because as of 2021, smartphones are the most owned and used device globally.

Yet 20% of marketers do not make their emails mobile-friendly.

17. Emails opened on desktop have 3x more click rates than emails opened on smartphones and tablets.

(Mailchimp)

5,000 – 9,999	22.31%	2.80%	12.57%	0.14%	0.01%
50,000 – 99,999	16.33%	1.91%	11.70%	0.10%	0.01%

These latest email marketing benchmarks from GetResponse indicate that segmented email campaigns are far more successful than those sent to all potential customers.

That’s only a one percentage point difference. Still, a personalized subject line is a way to go during segmented campaigns.

Needless to say, a subject line that has 1-60 characters has lower engagement rates.

23. Emails with a preheader have higher average open rates — 22.28% vs. 19.33% open rates of emails without a preheader.
