UPDATE (9/21/2017): Great news, email geeks! Media query support in the Outlook app is being rolled out for iOS and Android! Read all the details over on the Litmus blog.
UPDATE (8/12/2017): If you didn’t see on the Email Geeks slack channel, it was confirmed earlier this week by Kate Everitt from Microsoft that they are working on improving the rendering of the Outlook app for both iOS and Android, including support for media queries, and this would apply to all accounts used with the app. We don’t know when this change will be, but this is great news to hear!
There are many 3rd party email client apps available on iOS and Android to use. With the release of iOS 10, iOS users can even delete the default iOS Mail app, especially if they prefer using a 3rd party app (here’s looking at you, Gmail). And the support across these apps can vary, even between the same apps across iOS and Android devices.
One of these apps is the Outlook app — which used to be one of the best email apps available. You’re probably thinking I’m crazy, considering it’s Outlook after all, but it’s true! The Outlook app used to support responsive emails and media queries, and rendered quite similar to the iOS app. That’s the key here… used to.
