What's wrong with Google's own stock 4.4 email app (rather than GMAIL app) ?
It can be side loaded easily and is certainly one of the best apps for email on android devices.

I haven't used it in a while but recall the reason I moved away from it was the lack of autosizing so that the message would automatically fit the screen. Without this functionality, reading email was a P.I.T.A--so much side scrolling and/or pinch to zoom. I found it so annoying it prompted me to set up my Gmail account to automatically pull in messages from my non-Gmail accounts so they everything was viewable in the Gmail app.
Has this been added to the stock email app?
