Frequently Asked Questions
Is encrypted email really more private than Gmail?
Yes, significantly. Gmail scans your emails for advertising and data profiling. Encrypted email providers like Proton Mail and Tuta use end-to-end encryption so even the provider cannot read your messages. Proton Mail uses zero-access encryption for emails at rest.
Can I send encrypted email to anyone, even Gmail users?
Yes. Proton Mail and Tuta allow sending password-protected encrypted emails to any recipient. The recipient opens the message via a secure link with the shared password. For full E2EE between both parties, both need to use the same service or PGP-compatible clients.
Is Proton Mail or Tuta better?
Proton Mail is better for most users: larger ecosystem (VPN, Drive, Pass), PGP compatibility, Bridge for desktop clients, and Swiss jurisdiction. Tuta is better for budget users ($3/mo vs $3.99/mo) and uniquely encrypts subject lines. Tuta has no IMAP/SMTP support.
Can governments force encrypted email providers to hand over data?
They can compel providers to hand over what they have. With zero-knowledge encryption (Proton Mail, Tuta), the provider cannot read email content — they can only provide metadata like IP addresses. Proton Mail offers Tor access to mitigate even IP logging. Swiss and German laws set a higher bar than US jurisdiction.
Is encrypted email hard to use?
Modern encrypted email is as easy as Gmail. Proton Mail and Tuta have polished web and mobile apps. Encryption between users of the same service is automatic. StartMail makes PGP one-click simple. The only complexity is sending encrypted email to non-users (requires a shared password).
