Tutanota
German encrypted email service with a focus on privacy, sustainability, and open-source development.
Overview
Tutanota is a German encrypted email provider that takes privacy to the extreme. Unlike other services, Tutanota encrypts not just the email body but also subject lines and contacts—a unique feature in the industry.
Founded in 2011 in Hanover, Germany, Tutanota operates under strict German and EU privacy laws (GDPR). The company is committed to sustainability and runs on 100% renewable energy.
Key Features
Subject Line Encryption
Most encrypted email services only encrypt the message body. Tutanota encrypts everything, including subject lines, preventing metadata analysis.
Built-in Encrypted Calendar
Tutanota includes a fully encrypted calendar at no extra cost, making it easy to replace both Gmail and Google Calendar in one switch.
Custom Domain Support
Paid plans support custom domains with full encryption, perfect for businesses wanting branded email addresses.
Privacy & Security
Tutanota uses AES-256 and RSA-2048 encryption with perfect forward secrecy. All code is open source and has been audited. They cannot decrypt your data even if legally compelled.
