How to archive gmails in GS4 stock email app I kind of like the stock email client in Galaxy S4, but I don't use it since I haven't figured out how to set it up to archive mails instead of deleting them.

I subcribe to Google's philosophy "archive, don't delete" but is that possible with stock email client on GS4?
Only Gmail app currently supports archiving for Gmail. Other mail providers do not have the concept of archiving emails, so this is limited only to Gmail and hence to Gmail app alone. 

If you want to archive the emails, you should use Gmail app, I see no other workaround.
