One-Click Email Encryption
kMail enables encryption with a single click using ECC and OpenPGP, ensuring messages are readable only in your account. Compliant with FADP for sensitive data like medical info, it works across providers. Virus scanning and anti-spoofing via SPF/DKIM/DMARC add layers of protection. Backups across Swiss data centers allow restores up to 30 days.
AI Assistance for Email Management
Integrated Euria AI drafts replies considering context, corrects spelling/grammar, translates while preserving style, transcribes audio, and enables OCR search. All processing occurs in Switzerland without data retention or external use, maintaining privacy.
Cross-Device Synchronization
Full sync of emails, contacts, and calendars via IMAP/CalDAV/CardDAV keeps everything updated on web, iOS, Android, or desktop clients. Open-source apps ensure transparency. Attachments up to 3GB route through kDrive for seamless sharing.
Unlimited Storage and Scalable Plans
Free tier includes 20GB email + 15GB kDrive. Paid plans offer unlimited email storage, from CHF 1.76/user/month (kSuite Standard annual) up to Enterprise at CHF 13.83/user/month with Custom Brand. Supports 50 aliases free, custom domains, and up to 300 users.

End-to-End Encryption for Emails, Subjects, and Attachments
Tuta encrypts emails automatically between users, covering subjects, bodies, and attachments. External recipients get password-protected links. Contacts and calendars receive the same treatment, ensuring only sender and recipient access data. This zero-knowledge setup means Tuta cannot read user content.
Post-Quantum Cryptography
TutaCrypt protects against future quantum computer threats. The protocol combines Kyber-1024 for key exchange, X25519, and AES-256. New accounts use it now; older ones follow soon. This forward-thinking approach sets Tuta apart in long-term security.
Multi-Platform Apps and Integrated Tools
Native clients run on web, Android (Google Play and F-Droid), iOS, Windows, macOS, and Linux. A unified app handles email, calendar, and contacts. Features include unlimited search via encrypted indexes (premium), 25 MB attachments, HTML signatures, and offline support. Standalone calendar launched in 2024.
