Protects against the following threat(s):
- :material-server-network: Service Providers{ .pg-teal }
- :material-target-account: Targeted Attacks{ .pg-red }
The email clients we recommend support both OpenPGP and strong authentication such as Open Authorization (OAuth). OAuth allows you to use Multi-Factor Authentication to prevent account theft.
Email does not provide forward secrecy
When using end-to-end encryption (E2EE) technology like OpenPGP, email will still have some metadata that is not encrypted in the header of the email.
OpenPGP also does not support 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? Consider using a medium that provides forward secrecy:

Recommended Configuration
We recommend changing some of these settings to make Thunderbird a little more private.
These options can be found in :material-menu: → Settings → Privacy & Security.
Web Content
- Uncheck Remember websites and links I've visited
- Uncheck Accept cookies from sites
Telemetry
- Uncheck Allow Thunderbird to send technical and interaction data to Mozilla
Thunderbird-user.js (advanced)
thunderbird-user.js is a set of configuration options that aims to disable as many of the web-browsing features within Thunderbird as possible in order to reduce attack surface and maintain privacy. Some of the changes are backported from the Arkenfox project.
Platform Specific
Apple Mail (macOS)
{ align=right }
Apple Mail is included in macOS and can be extended to have OpenPGP support with GPG Suite, which adds the ability to send PGP-encrypted email.
:octicons-home-16: Homepage{ .md-button .md-button--primary } :octicons-eye-16:{ .card-link title="Privacy Policy" } :octicons-info-16:{ .card-link title=Documentation}
Apple Mail has the ability to load remote content in the background or block it entirely and hide your IP address from senders on macOS and iOS.
Canary Mail (iOS)
{ align=right }
Canary Mail is a paid email client designed to make end-to-end encryption seamless with security features such as a biometric app lock.
:octicons-home-16: Homepage{ .md-button .md-button--primary } :octicons-eye-16:{ .card-link title="Privacy Policy" } :octicons-info-16:{ .card-link title="Documentation" }
Warning
Canary Mail only recently released a Windows and Android client, though we don't believe they are as stable as their iOS and Mac counterparts.
Canary Mail is closed-source. We recommend it due to the few choices there are for email clients on iOS that support PGP E2EE.
FairEmail (Android)
