Proton Mail is an end-to-end encrypted email service founded in 2013 in Geneva, Switzerland. It uses client-side encryption to protect email content and user data before they are sent to Proton Mail servers, unlike other common email providers such as Gmail and Outlook.com. The service can be accessed through a webmail client, the Tor network, or dedicated iOS and Android apps. Proton Mail is run by Proton AG, which is based in the Canton of Geneva. The company also operates Proton VPN, Proton Drive and Proton Calendar. Proton Mail received initial funding through a crowdfunding campaign. Although the default account setup is free, the service is sustained by optional paid services. Initial membership was by invitation only, however beginning in March 2016, Proton Mail was opened to the public. Acquiring no fewer than 2 million users by 2017, membership grew to almost 70 million by 2022.
