Gefällt eigentlich gut . funktioniert nicht immer . Ausschlusskriterium so far. Da OpenSource werde ich's ab und an wieder testen.
Light weight, functional and stable The Android default email app is v boring n dull. I use K-9 for my two Outlook, one Yahoo and one own domain accounts. My two Gmail accounts are handled by default Gmail app. Though I thought it was slow in push notifications, but that seems to be working ok now. Everything I want from an email app works flawlessly in K-9. It's lightweight and superior in overall performance. Thumbs up!
Rapid sync, no clutter, privacy Thanks to the developers for this wonderful application which replaces my android stock app. I almost gave up on finding a mail app which doesn't ask for a ton of permissions until I found K9. A few minor suggestions for improvements: It should be possible to move mails to folders of different accounts, and generally the moving of mails could still be simplified. Another desirable feature would be a rapid delete gesture and an undo button for the last move/delete action.
Edit May 18th 2016: Has started reporting wrong sender in emails. Headers are correct, but every email is being reported as coming from a single sender. Minus 1 star... Previous review : Much better than the stock email client. A big plus is allowing multi-select and unified account view options
Much better than factory mail client I love that you can store messages on the SD card as I was running out of memory on the device storage. I have Exchange sync perfectly an IMAP account and also Gmail and everything works perfectly. For people having issues with Exchange Google which URL you are supposed to use.
4 years of happy mobile mail :) This is an outstanding email app! It works perfectly, super customizable! Also has a very unique and comfortable interface. It's that simple to describe it, nothing else to say, really, because it's just great! Last year, when I bought a new phone, i didn't even try its own mail client app because i got used to k9 a lot. Thanks for your great app and amazing support!
