Get encrypted email with top-notch security

Sensitive content requires extra protection: simply encrypt as needed and make emails readable only for the sender and the recipient.

Email encryption

What is encryption?

As a European email provider, GMX adheres to the highest standards of security and data protection: within the network, transmission paths are automatically encrypted and your emails are only stored in secure European data centers. In special cases, however, you may require additional protection when sending emails: for example, when sending sensitive content such as contracts or doctor’s notes. This is exactly why GMX offers encrypted communication, a tested, free, and easy to use security procedure that you can also use on the go.

Encryption describes the process behind making emails unintelligible for unauthorized parties. Users may want to encrypt their messages for a variety of reasons. Perhaps the content of the message is especially sensitive, or the user simply wishes to encrypt their communication for personal privacy reasons. Regardless, email encryption offers a useful and reliable way to communicate securely and without worrying that the information related to an email, whether the email addresses of the sender or recipient or its content or attachments, can be read by any parties other than those authorized to do so.

How does encryption work?

GMX makes use of the OpenPGP (for ‘Pretty Good Privacy‘) end-to-end encryption procedure, which provides the highest standard of security for encrypting emails. Since its introduction, OpenPGP has never been cracked, meaning it’s extremely secure.

But how does PGP email work? The OpenPGP method makes use of two complementary keys for encryption and decryption: one public and one private. The public key is used to encrypt the message, and the private key is used to decrypt it. The public key is shared with the party you’re securely communicating with and allows for the encryption of the email. The encrypted message, which is ‘assigned‘ to the owner of the private key, can only be decrypted using the private key. This is why it’s so important for the private key to be kept secret.

GMX’s free email encryption makes sending and receiving encrypted emails easy. Users can take part in encrypted communication the same way they would regular email communication.

Information & details

Encryption gold standard

Emails are encrypted using OpenPGP (from Pretty Good Privacy), the open source gold standard for secure and speedy end-to-end encryption of email content. OpenPGP has not been cracked since its introduction, meaning it is considered completely secure. Encrypted communication provides the greatest level of security and makes the sender, recipient, subject (metadata) and content inaccessible to unauthorized parties.
