Proton Mail vs Tuta

The two best-known encrypted email providers. Both keep stored mail unreadable to themselves; Tuta also encrypts subject lines and is cheaper with your own domain, while Proton works in Apple Mail and Outlook through its Bridge app.

Which one to pick

  • You want to keep using Apple Mail, Outlook or Thunderbird (through Proton's Bridge app on a paid plan)
  • You want built-in PGP to write to people who use it
  • You want a Swiss company, or already use other Proton apps

  • You want your own domain for less: €36 a year with 3 domains, against $47.88 with 1 on Proton Mail Plus
  • You're happy to use the provider's own apps (Tuta has no IMAP at all)
