User reviews of K-9 Mail
This is easy to set up easy-to-understand

After I tried others like k-9, TouchDown and Moxier , I must say Emoze Push Mail is the best!!! It works great and really easy to use. I have my corporate and gmail account on push and the battery consumption is very low. In addition it has cool security features which enable to remotely wipe or lock the device by SMS or email. I can't believe it's free… :-)

A client mail very useful with many functions, can work also with gmail accounts. Un client di posta fatto molto bene,funziona anche con Gmail e altri accounts.

Used this app 2 years ago, the "unread" mail count is buggy, Gmail push is very slow (few hours delay), uninstalled. Installed this app few days ago, same problem, disappointed... Folder level is complex, mail will download to your phone anyway despite of settings. Switch back to stock Gmail app. Devs should fix basic email function before moving any further

Broken Was my favorite email app until the last update. Now it tells me my server information is wrong and continues to try and send mail causing huge battery drain. Had to switch to the default mail app b/c now it's not usable. Please fix this asap!

Great app, personally could do with a couple more features. Great app really brought back alot of features that were lost from earlier Android mail. Really easy to setup and touch wood not a single crash from this gem. Bad: I am using this for 3 email accounts on my home screen but I can't change the name of the home screen link. All show k-9 mail, could do with renaming feature. Also all other mail apps tend to show the number of unread emails on the icon this doesn't. Lastly, no feedback option within the app to say this stuff!?
