• Use custom domains cautiously: Hosting your email on a custom domain improves branding but could expose your domain registration unless shielded.
• Encrypt subject lines (Tutanota only): Protect sensitive email subjects from passive eavesdroppers by leveraging Tutanota’s built-in encryption.
• Leverage Proton Mail’s PGP for external encryption: Proton Mail supports PGP import/export, useful for communicating with users outside the platform securely.
• Keep apps updated: Regularly update mobile and desktop clients to patch vulnerabilities and access new security features.

Which One Should You Pick?

After spending weeks testing this myself, here’s what I found that most reviews don’t mention.

If you prioritize open-source transparency and metadata privacy, Tutanota is the stronger candidate, especially for users valuing calendar and contact encryption. Conversely, if you require PGP support, a larger server infrastructure, and Swiss jurisdiction, Proton Mail fits better.
