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.

Ein Muss für mehrere Mail-Postfächer

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

July 2014 It probably the best email client out there for android. But the Dev really needs to fix the CPU and memory usage problem. It sucks battery power greatly and creates bad CPU performance lag. Hopefully fixed soon???

Used to be better than google spyware Used to be great, but... Since the devs stopped listening to users it has become useless if you use ssl self signed certs on SUPPORTED operating systems. Devs say it is insecure. Thats MY problem, not theirs. Now have to find something that WORKS instead of this now useless piece of junk.
