Tuta Review 2026: Tested for 90 Days
Our verdict
Tuta (formerly Tutanota) is the best encrypted email for privacy purists on a budget. It’s the only major provider that encrypts subject lines by default, uses its own encryption protocol (avoiding PGP weaknesses), and is actively building post-quantum encryption (TutaCrypt). After 90 days, we found the interface clean, the desktop apps solid, and the $3/mo paid plan the cheapest in the category.
The trade-off: no PGP interoperability and no IMAP/SMTP support.
Key features
- Proprietary E2EE (AES-256 + RSA-2048, not PGP)

- Encrypted calendar and contact book built-in
- Full-text encrypted search (client-side)
- Anonymous sign-up (no phone number required)
- Custom domain support on paid plans
- Post-quantum cryptography roadmap (TutaCrypt)
- Native desktop apps (unlike Proton Mail’s Bridge approach)

- No IMAP/SMTP — locked into Tuta’s own clients
- Smaller user base and less third-party integration than Proton Mail
- German authorities have compelled monitoring in past cases
- Free tier limited to 1 GB
