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!

It’s “you’ll never go back” better HEY replaces workarounds, messy hacks, and daily frustrations, with built-in workflows, effortless organization, and clever features that levels-up email in meaningful ways. Screen emails like you screen calls You screen your calls, so why can't you screen your emails? With HEY, you can. HEY puts you in complete control of who's allowed to email you. Don't want to hear from someone? Screen them out and won’t hear from them again. Naturally grouped Inboxes are typically an intertwined mess of new and old messages haphazardly mixed together. Yuck. With HEY, new messages are always grouped together at the top, and previously seen emails are always at the bottom. Neat and orderly by default. No need to wade through the inbox jungle with a machete. Spread ’em out, read ’em together Let's say you have 7 unread emails. Why do you have to open one, close one, open one, close one, open one, close one, and so on. It's rediculously inefficient. With HEY, you can open multiple emails at once and just scroll though them, just like you would a newsfeed. It's a revolutionary way to read your emails. You'll never go back to the old way. Find files without pulling your hair out If you’re looking for an attachment, why should you have to find an email first? That’s backwards. With HEY, you get an attachment library that gathers up every attachment you’ve ever received in one organized, siftable place. Just set it aside Sometimes you get emails you need to reference later - travel info, handy links, numbers you need, etc. With HEY, you can 'Set Aside' any email in a neat little pile for easy access whenever you need it. At hand, but out of your face. Put receipts in The Paper Trail Receipts, confirmations, and transactional emails getting in your way? With HEY, you can send those types of emails to The Paper Trail where they'll be out of your way, but easy to find when you need them. Blocking email spies 24/7/365 Many companies track which emails you open, how often you open them, and even where you were when you opened them. It's a massive invasion of your privacy. HEY blocks these trackers and tells you who's spying on you. Fix bad subjects without busting threads If you don’t start the thread, you're often stuck with other people’s generic, non-descriptive email subjects. With HEY, you can rename a subject so it makes sense for you without changing things for the other person. Add private notes to any email thread Conversations may start in email, but they may continue somewhere else. Some emails turn into lunches or calls or video conferences. Where do you put the notes from those - especially if they relate to the initial email conversation? With HEY, you can add personal, private notes (and files) to any thread. This way you keep everything related to the conversation on one page, even if it didn't all happen via email. Notifications you control HEY push notifications are off by default so your phone doesn’t steal your attention every time an inconsequential email hits your inbox. However, HEY lets you selectively turn them on for specific contacts or threads so you don't miss the things you really care about. A built-in ‘Reply Later’ workflow What if you need to reply, but you don't have time right now? With HEY, just click the “Reply Later” button to move an email to a dedicated ‘Reply Later’ pile at the bottom of the screen so you don’t lose or forget it. Stop heavy senders from dominating your inbox When you get lots of emails from someone, they can take over your Inbox. With HEY, you can choose to bundle a sender into a single row. This means no matter how many emails they send you, they'll only take up a single row in your Inbox. Clean, controlled, and calm. Get off threads without having to ask Stuck on a mega email chain and want off? Good luck asking someone to remove you. With HEY, you can unfollow any thread and replies won’t show up as new emails anymore. Out of your face forever.
