ProtonMail

ProtonMail is the world's largest secure email service founded in 2013 in Geneva, Switzerland by scientists who met at the CERN research facility.  ProtonMail uses end-to-end encryption and zero access encryption to secure emails, meaning even they cannot decrypt and read your emails. As a result, users’ encrypted emails cannot be shared with third parties. Located in Switzerland, all ProtonMail’s user data is protected by strict Swiss privacy laws.
