   Proton Mail is an end-to-end encrypted email service based in Switzerland. Messages between Proton users are encrypted automatically, emails to others can be password-protected, and stored mail uses zero-access encryption so Proton cannot read it.

   Tuta

   Tuta, formerly Tutanota, is an open-source encrypted email and calendar service based in Germany. It encrypts mailbox contents end to end, including subject lines and contacts, and uses post-quantum cryptography for new accounts. Because it relies on its own encryption, it works through Tuta's apps rather than IMAP clients. A free plan exists, and paid plans add custom domains and more aliases.

   Pros

   • Encrypts subjects and contacts, not just message bodies
   • Post-quantum cryptography for new accounts
   • Open source apps and a free plan, with servers in Germany

   Cons

   • No IMAP support, so you must use Tuta’s own apps
   • Free plan is limited in storage and features
   • Fewer integrations and features than mainstream providers
