Overview
Proton Mail is an end-to-end encrypted email service based in Switzerland that provides strong privacy protections through zero-access encryption. The service encrypts emails on Proton's servers using AES-256 encryption in a way that even Proton cannot decrypt them, ensuring that stored emails remain encrypted and inaccessible to Proton or third parties. When you email another Proton Mail user, emails are automatically end-to-end encrypted using OpenPGP. Proton Mail offers enhanced tracking protection, encrypted contacts, and two-factor authentication including hardware security keys. The service is based in Switzerland, which has strong privacy laws and is not part of intelligence-sharing alliances, providing robust legal protections. Proton Mail's client applications are open source and have undergone independent security audits, including a SOC 2 Type II certification. The service offers both free and paid plans, with the free tier providing basic encrypted email functionality with limited storage. Proton Mail is available as a web application and mobile apps for iOS and Android, with Proton Mail Bridge available for desktop email clients.
