-Discover free, open-source, and secure email clients, along with some email alternatives you may not have considered.
+Our recommendation list contains email clients that support both [OpenPGP](/encryption/#openpgp) and strong authentication such as [Open Authorization (OAuth)](https://en.wikipedia.org/wiki/OAuth). OAuth allows you to use [Multi-Factor Authentication](/multi-factor-authentication) and prevent account theft.
 
 ??? Attention "Email does not 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.

+
+    **Apple Mail** is included in macOS and can be extended to have OpenPGP support with [GPG Suite](/encryption/#gpg-suite), which adds the ability to send encrypted email.
+
+    !!! note
+        For iOS devices we suggest [Canary Mail](/email-clients/#canary-mail) as it has PGP support which means you can send end-to-end encrypted email.
