description Encrypted Email Services Overview
Encrypted email services use cryptography to limit who can read message contents. Providers such as Proton Mail support end-to-end encryption, in which messages are encrypted for the recipient rather than being readable by every system handling delivery. This can be valuable for journalists and activists, as well as individuals exchanging sensitive personal or professional information. The protection depends on the service and how a message is sent.
Proton-to-Proton messages are end-to-end encrypted by default, while communication with an outside provider may require password-protected messages or compatible encryption keys. Ordinary external email does not automatically gain the same protection. Encryption also does not guarantee that a recipient's device is safe or conceal every piece of message metadata.
