Which service should you choose?
The right choice depends on what you actually need. Here is our honest assessment.
🧅 Choose Onion Mail if...
You need genuine anonymity — no phone, Tor-native access, anonymous payments, and want your communications protected against future quantum computers. Best for journalists, activists, and privacy-focused users.
Choose ProtonMail if...
You want a polished, mainstream-friendly private email with a large user base and good mobile apps. Acceptable for privacy but not suitable for users who need to hide their identity completely.
Choose Tuta if...
You want open-source encryption and affordable pricing. Good for general privacy but no Tor access and no PGP support — not suitable for users who need Tor or standard encryption interoperability.
