Alternatives to Tuta
Encrypted German mail with quantum-safe crypto
Tuta ranks #2 of 12 in Email services, with an Alt Score of 93. It is licensed under GPL-3.0, freemium from €3/month and available on Windows, macOS, Linux, iOS, Android and Web. 12 of 12 checklist rows are verified against a public source.
Privacy-conscious individuals, journalists, activists, and businesses (including regulated fields like healthcare and finance) who want an email provider that doesn't read or mine their data.
End-to-end encrypted email, calendar, and contacts, with encryption applied automatically by default, not opt-in. Includes post-quantum cryptography, ad-free and tracking-free use, custom domains with aliases, and apps for web, mobile (iOS/Android), and desktop. Servers run in Germany on renewable energy under GDPR, with an open-source codebase for independent security review.
Users sign up for a free account (with paid tiers for custom domains and extra storage) at app.tuta.com or via the mobile/desktop apps, and all mail, calendar entries, and contacts are encrypted client-side automatically as they're created or received, requiring no manual setup.
