I was stupid enough to update my Android phone and now I can't use the native mail app anymore (I'm being directed to the Gmail app).
Now I always tested my mail templates on my phone first before running a Litmus test, as I wanted to see live what was happening. Working on a mail with tabs and a slider I need that live test more than ever and so I'm looking for a replacement mail app that supports responsive code so I can test.

I tried Outlook.com as I've seen responsive mails in it, but the code used for the tabs and slider aren't supported by Outlook.com (desktop or mobile), so I can only see the fallback block.

Which mobile apps do you use to test your code?
