Mobile Email Stats Rundown

Projections meanwhile show that the number of email users will increase to more than 4.48 billion by 2024.

The most recent mobile email statistics reveal that mobile is gaining traction at the expense of webmail.

To see things from a different perspective, nearly 281 billion emails had been sent and received on a daily basis in 2018, and projections are that by 2023 the number will top 372 billion daily emails, most of which will be opened on mobile.


3. US email usage stats show that email reached a 90.9% market penetration rate in 2019.

Statista’s report points to growing email market penetration and usage development in the US between 2013 and 2019. In addition, the number of email users has been steadily rising (by 2.6% in 2015 compared to 2014), but in 2019 the growth slowed down to 1.2% which is still a solid percentage. 


4. Emails are the first thing 58% of people check in the morning.

Mobile usage statistics confirm that instead of checking Facebook or their favorite influencers’ Instagram stories, almost 60% of people check their emails first thing in the morning, while 20% like to search the world wide web.

Studies provide evidence that human beings process images 60,000 times faster than text. Perhaps this is why the average person spends less than a minute reading a newsletter.

20. Email replies sent from phones are 60% shorter than desktop.

EmailMonday’s mobile email usage statistics reveal that people are lazier when writing a response from a phone. The primary cause of this action lies in the accessibility of a desktop — it has a bigger keyboard. Plus, users can view the whole large mail on a 22+ inch screen, which is not the case with smartphones’ 5-6 inch displays. 


21. Protecting against spam and malware will remain a critical problem for all companies.

Research reveals that companies will continue to experience issues with malware and spam from emails. Mobile email trends suggest that hackers will continue to produce complex and sophisticated malware that will make companies spend more on advanced anti-malware protection. The most common malware attacks on desktop and mobile are blended. These are emails that do not contain any malware attachments but instead contain a link that will take the user to a malware-infected website.



The age of information has brought so much innovation that it has fundamentally changed marketing. It was the email that kick-started the digital age and, even today, email marketing remains a valuable method to generate new leads for companies. New times bring new challenges, though, and mobile optimization is the key. As these mobile email statistics show, marketers need to stay up to date with the latest trends in mobile if they want to make the most out of their email campaigns.
