Give it a chance

Not perfect but ranks as one of the best email apps around. Its a cross btw the mailbox app. and the inbox cube Mail app.

The more I use this app the more I features I discover. Like it separates documents, pics, and video into their own categories making them easy to find the emails that contains them.

A few flaws like the notifications are a bit buggy and dont always work. When viewing a document and after zooming in to view it. Leaving the document to return to the email app. seems impossible or maybe I just havent found a way. The app. also freezes occasionally. But overall Im impressed.
