ProtonMail is a partly open-source end-to-end encrypted email service founded in 2013 at the CERN research facility by Andy Yen, Jason Stockman and Wei Sun. ProtonMail uses client-side encryption to protect email contents and user data before they are sent to ProtonMail servers, in contrast to other common email providers such as Gmail and Hotmail. The service can be accessed through a webmail client or dedicated iOS and Android apps.
ProtonMail is run by Proton Technologies AG, a company based in the Canton of Geneva, and its servers are located at two locations in Switzerland, outside of US and EU jurisdiction. The service received initial funding through a crowdfunding campaign. The default account setup is free and the service is sustained by optional paid services. As of January 2017[update], ProtonMail has over 2 million users. Initially invitation-only, ProtonMail opened up to the public in March 2016.
On 16 May 2014, ProtonMail entered into public beta. Within three days, ProtonMail was met with an overwhelming response and was forced to temporarily suspend beta signups while they worked to expand server capacity.
On 31 July 2014, ProtonMail received US$550,377 from 10,576 donors through a crowdfunding campaign on Indiegogo, while aiming for US$100,000. During the campaign, PayPal froze ProtonMail's PayPal account, thereby preventing the withdrawal of US$251,721 worth of donations. PayPal stated that the account was frozen due to doubts of the legality of encryption, statements that opponents said were unfounded. The restrictions were lifted the following day.
