Send encrypted emails easily and securely

For an extra layer of security for emails with sensitive content, add GMX encryption.

Email encryption

Email encryption explained

GMX follows the highest standards of security and data protection as a European email provider. For example, GMX only stores emails in secure European data centres and encrypts all transmission paths automatically. Sometimes, however, you’ll want even more security when sending emails containing sensitive content like contracts or doctor’s notes. For this reason, GMX provides its users with the option of using encrypted communication, a reliable, free, and easy-to-use layer of security that is also available for mobile devices.

Encrypting an email makes the information it contains unreadable to anyone except those authorised. This may be desirable especially for emails including sensitive content, or simply for general personal privacy reasons. Email encryption is the best way to communicate securely via email. You won’t have to worry about the content and attachments of your email or the addresses of the sender or recipient falling into the hands of third parties.

How does email encryption work?

GMX email encryption relies on the OpenPGP end-to-end encryption procedure. This is the highest standard of encryption security, and since its introduction, OpenPGP has not been cracked.

How does PGP email work? OpenPGP uses two complementary keys: a public key for encryption and a private key for decryption. The public key is shared with the party you’re communicating with and encrypts the email. Then, the encrypted message is “assigned” to the owner of the private key, meaning it can only be decrypted using this private key. This makes it extremely important to keep the private key safe and secret.

With free email encryption from GMX, sending and receiving encrypted emails is simple, and makes taking part in encrypted communication just as easy as sending a regular email.

The gold standard of encryption

Further information

Gold standard for encryption

OpenPGP (short for “Pretty Good Privacy”) is the open-source gold standard for fast and secure end-to-end email encryption, which is why GMX relies on it. OpenPGP has never been cracked, making it extremely secure. When emails are encrypted using OpenPGP, the sender, recipient, subject, metadata, and the contents are made completely inaccessible to unauthorised parties.

Simple to use

Further information


GMX users can enjoy unhackable email communication without needing to have expert knowledge, thanks to GMX’s email encryption procedure. GMX made the OpenPGP procedure as simple as possible, optimising it for user-friendliness. This was made conceivable because of its cooperation with Mailvelope, an open-source project based in Heidelberg, Germany, that offers a browser-based OpenPGP solution of its own.

Security you can trust

Reliable security

GMX makes its encryption procedure transparent by disclosing how the process works as well as the source code behind it. Plus, it’s audited by independent external security experts. You can therefore rest assured that the security of GMX encryption can be counted on, even with its more user-friendly procedure.
