Proton Mail

Proton Mail is a Swiss encrypted email service that protects conversations with end-to-end encryption and zero-access storage, meaning even Proton cannot read your messages or attachments. Built by the team behind CERN-era cryptography research, it replaces Gmail with a privacy-first inbox that blocks trackers, hides your IP, and lets you sign up without a phone number.

The platform runs on open-source, independently audited code and uses OpenPGP under the hood, interoperable with any PGP client. Web, desktop, Android, and iOS apps share the same vault, and extras like PhishGuard, password-protected external messages, hide-my-email aliases, scheduled send, snooze, and undo send round out a polished daily-driver experience.

Key benefits:

• End-to-end encryption keeps message bodies and attachments unreadable to Proton and intruders.
• Zero-access architecture encrypts stored mail with keys only the user controls.
• Tracker and phishing protection strips pixels and flags impersonation automatically.
• Custom domains supported on Mail Plus (1) and Proton Unlimited (3) plans.
• Hide-my-email aliases mask your real address when signing up for services.

Proton is headquartered in Geneva and operates its own datacenters in Switzerland, shielded by the Swiss Federal Act on Data Protection and outside EU and US jurisdiction for user-content requests. The service is GDPR-compliant, ISO 27001-certified, and fully open source on every client.

Trusted by over 100 million accounts and 100,000 organizations, Proton Mail is ideal for journalists, activists, lawyers, and anyone who wants Gmail-grade polish without ad-driven surveillance.
