Email, cloud & news - all in the account! The free GMX Mail App is your faithful companion on the road! The Smart Inbox takes a lot of work off your hands! Incoming emails arrive automatically in the inbox of your mailbox. One after the other, in chronological order - but mixed thematically. In the smart inbox, new e-mails are displayed in individual categories - automatically, for a better overview. In the inbox, everything remains the same. With the cloud, GMX offers you a professional, free storage solution. It is equally suitable for file backup as well as for simple and fast sharing of large files - e.g. photo series. Thanks to the highest security standards, the Cloud is virtually undestroyable and with Cloud made in Germany, it also meets the highest standards in terms of data protection. Particularly useful: The GMX Mail app also supports your other GMX Mail accounts. So you always keep an eye on all your GMX mailboxes, in one app! Our "Push Sounds" are especially popular: these individually adjustable notifications sound as soon as a new email is received. Handling is also very simple and intuitive, and the interface, which is adapted to the smartphone, is particularly user-friendly. The battery-saving e-mail push service and the secure, protected access with PIN protection are further plus points. For these very reasons, the GMX Mail app has already been downloaded and installed more than a million times!

Verdict

The call

The clearest difference is review sentiment: GMX at 71% against BT Email's 17%. GMX also leads on update cadence (every 2 weeks vs every 3 months) and rating (4.7 vs 4.3). BT Email's advantage is in-app purchases (none vs 19) and ads (none vs shown). On price and device support there is nothing between them.
