About 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.
Why choose Proton Mail over Gmail?
The decisive argument is data jurisdiction. Gmail is headquartered in US, which means personal data processed through it can be subject to non-EU legal regimes — the US CLOUD Act, FISA 702, or similar laws depending on the provider. After the 2020 Schrems II ruling, EU organisations must carry out a transfer impact assessment for every such data flow.
Proton Mail removes that overhead. As a Switzerland-based provider, it operates natively under GDPR, and data stays inside the EU/EEA by default. For regulated sectors — health, public administration, finance — that's not a nice-to-have but a requirement. For everyone else, it's concentration-risk insurance: you avoid depending on a single non-EU jurisdiction that can change the rules without warning.
