No junk. No ads. No trackers. Just privacy.

Proton Mail is the world’s largest provider of end-to-end encrypted email. Your emails are secured with end-to-end encryption and zero-access encryption, meaning only you and your intended recipients can read them — not even Proton can see their content.

Proton Mail’s end-to-end encryption is built-in and runs automatically in the background, so you don’t need any technical expertise to send or receive private, secure emails.

Millions of people around the world — including journalists, activists, and everyday users — trust Proton Mail to protect their most sensitive communications.

End-to-end encryption is a way to keep messages private by locking them with encryption before they leave your device, so only the person you're sending them to can unlock and read them. No one else — not email providers, hackers, or governments — can see what’s inside.

Protecting your emails with end-to-end and zero-access encryption helps you take back control of your data and acts as insurance against future data breaches or changes to digital privacy laws.

Choosing a secure email service like Proton Mail supports the fundamental rights of privacy and free expression — helping to defend democracy by ensuring that people everywhere can communicate freely and securely.

Yes, Proton Mail is significantly safer. Email providers like Gmail, Outlook, and Yahoo scan your emails, and their business models are based on serving you personalized ads. They can also share your data with third parties. Unlike Proton Mail, they hold the encryption keys on their servers, meaning they can access, analyze, or hand over your emails to authorities if requested.

Proton Mail does not scan your emails, serve ads, or sell your data. Your messages are stored with zero-access encryption, giving you stronger privacy protections and greater defense against data breaches.

Proton Mail will always offer a free secure email plan that provides the essential features you expect from your inbox with the same level of security as our paid plans. If you upgrade to a paid plan, you will unlock advanced features, including the ability to add more than one email address, extra storage, custom email domains, and unlimited messages. You’ll also be supporting our mission to build a better internet where privacy is the default.
