Mailfence vs Tuta Mail
Side-by-side comparison of features, pricing, ratings, and alternatives.
Mailfence is a secure and private email service based in Belgium, operating under strict European privacy law where only local judges with a court order can request user information. It provides end-to-end OpenPGP-compatible encryption and digital signatures, with encryption happening in the browser so that even Mailfence cannot read user emails.
Tuta Mail is an encrypted email service from Germany focused on privacy, offering end-to-end encryption, an ad-free interface, and no tracking. It describes itself as the world's first end-to-end encrypted email service with quantum-resistant cryptography, and complies with GDPR through a zero-knowledge architecture. All Tuta clients are fully open source and can be audited by security experts, with code available on GitHub. The service also includes an encrypted calendar and contacts, custom domain support, and is available on web, Windows, macOS, Linux, Android, and iOS, with a permanently free tier alongside paid Revolutionary and Legend plans.

- Encrypted search and some features work differently than standard webmail
- Based in Germany, which may matter for users with specific jurisdiction concerns
