My all time most favorite. The only thing missing in the app is the SEARCH option for Email subjects/contents and contacts. That's why it got 4! I hope the GMX team takes it serious. Thanks. Update: Thanks to the GMX Team for informing me that there is a search option. It worked. Now almost everything is great about this wonderful service/app except that you have to pay to integrate and sync the calender (through CalDAV). It would be great if the calender could be used without this third party thing.
This app is a serious battery drainer! It uses Google services to provide push email and for some reason it comes top of the list in the battery page; about 20% on my phone. I've now uninstalled and am back to using Aquamail for IMAP push email and the battery drain is now negligible at 1%. This needs looking into. It's also a very slow app; you have to wait several seconds before an email will open. Not recommended at all.
Used to be good but since around a week auto-sync and fetching of mails when screen is locked doesn't work anymore. When not starting the app and manually refreshing, I can fall easily hours behind my mails.
Not receiving any received mail, sending not working, reading mails never displayed. since Yesterday 17 January 2017. My network is fully functional, I can access GMX mail account from Linux Thunderbird. GMX om Note 5 Marshmallow not working anymore for about 20 hours.
Sync no longer worked on phone, but worked on computer. I uninstalled and installed again. Now if I want to log in it only says " please retry later " very disappointing performance for a German App
It used to be an excellent app, 5 years ago. Every new update deletes a function. Using gmx for over 15 years - it has deteriorated a lot.
