Upgrade to the secure alternative to Fastmail

With Proton Mail, you don’t need any special tools to protect your emails. We automatically lock your messages behind end-to-end encryption and zero-access encryption. Unlike Fastmail, Proton could not read your emails even if we wanted to.

Proton Mail blocks trackers so you can read your emails with peace of mind. PhishGuard and Link confirmation ensure you’ll never fall for phishing attacks.

Quickly unsubscribe from newsletters and mailing lists you don’t want with a single click.

RSVP for events right from your inbox. Create events, send invitations, and set reminders — all from your encrypted calendar.

We don’t show ads, not even on our Free plan. We make money when people upgrade to a paid plan for more storage and features.

All Proton apps are open source and audited by independent security experts. Founded by scientists, we believe in the principle of peer review to secure our code.

Proton is a global movement led by our community to fight for a better internet. By using Proton Mail, you’re supporting privacy and freedom online.

Because we’re based in Geneva, Swiss privacy laws protect all our users’ emails from arbitrary surveillance.

With our Easy Switch tool, you can move all your emails, contacts, and calendars to Proton Mail without any hassle.
