iPhone vs. Android: How to Get Your Email Looking Great on Both Platforms

With so many people using smartphones—and email being the most popular activity on those devices—it’s important to assess how your emails display on those small screens. There’s a lot to consider when it comes to mobile email design. On top of the multitude of smartphones, users have dozens of different email apps to choose from—each with their own set of rendering quirks. In this post, we take a look at differences in rendering across the numerous iOS and Android mobile email apps.


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.

As users update to the new mobile Gmail apps, we’re seeing image caching affect mobile open rates, specifically opens made with the Gmail app on Android. As Gmail open rates rise, there has been a corresponding drop in Android opens. Since January, Android opens have dropped 34%—now representing 8% of opens.
