Upgrade to the secure alternative to Fastmail
No one else should have the ability to access your data.
With Proton Mail, your emails are protected by end-to-end encryption, so no one — not even Proton — can read them.

The Fastmail alternative that can’t access your inbox
Proton Mail believes the internet should be private by default. That’s why, unlike Fastmail, your inbox is protected by strong encryption and Swiss privacy laws. Plus, you benefit from more storage space, more features, and stronger security.

What people say about Proton Mail
An alternative to Fastmail that respects your privacy
Encrypt your emails by default
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.
Block spy trackers and phishing
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.
Unsubscribe from emails you don’t want
Quickly unsubscribe from newsletters and mailing lists you don’t want with a single click.
Manage your calendar from your email
RSVP for events right from your inbox. Create events, send invitations, and set reminders — all from your encrypted calendar.
Always ad-free
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.
Open source and audited
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.
More than just email
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.
Based in Switzerland
Because we’re based in Geneva, Swiss privacy laws protect all our users’ emails from arbitrary surveillance.
