Top 10 Most Popular Email Clients of 2015

As another year wraps up, email is still reminding us that nothing in this industry is boring, despite what some naysayers would like to have us think! We tracked nearly 1 billion emails every month throughout 2015, measuring where and how your messages are opened around the world. While some things remained the same—the top three email clients in January were still the top three in November—there was some drama along the way.

 

53% of Emails Opened on Mobile; Outlook Opens Decrease 33%

We’ve been tracking email opens for more than 4 years. And it’s incredible to see how behaviors have changed over time. Mobile email was barely a blip on our radars in 2011, and made up just 8% of email opens. Fast forward to 2014, and nearly half of emails are opened on smartphones and tablets—a 500% increase in four years.
