Email That Puts Privacy First

Complexity, Simplified

Advanced cryptography meets modern design.


Our Story

ProtonMail was founded in summer 2013 by scientists who met at CERN and were drawn together by a shared vision of a more secure and private Internet. Since then, ProtonMail has evolved into a global effort to protect civil liberties and build a more secure Internet, with team members hailing from Caltech, Harvard, ETH Zurich and many other research institutions.

Today, we help our fast growing community of users from more than 120 countries protect their private data online. More than 10,000 supporters have assisted us in this mission by donating to make this project possible. Thanks to your support, we are continuing to develop state of the art privacy and security technology from our home base of Geneva, Switzerland.
