??? Attention "Email does provide forward secrecy"
When using end-to-end encryption (E2EE) technology like [OpenPGP](https://en.wikipedia.org/wiki/Pretty_Good_Privacy), email will still have [some metadata](/email/#email-metadata-overview) that is not encrypted in the header of the email.
OpenPGP also does not support [forward secrecy](https://en.wikipedia.org/wiki/Forward_secrecy), which means if either your or the recipient's private key is ever stolen, all previous messages encrypted with it will be exposed: [How do I protect my private keys?](/email/#email-encryption-overview).

**Canary Mail** is a paid email client designed to make end-to-end encryption seamless with security features such as a biometric app lock.
!!! attention
Canary Mail is closed source. We recommend it, due to the few choices there are for email clients on iOS that support [Pretty Good Privacy (PGP)](https://en.wikipedia.org/wiki/Pretty_Good_Privacy), end-to-end encryption (E2EE).
!!! note
Canary Mail only recently released a Windows and Android client we don't believe they are as stable as their iOS and Mac counterparts.
