ProtonMail

ProtonMail is a secure email service founded in 2013 by scientists and engineers from CERN and MIT. It is based in Switzerland, which has strict privacy laws, ensuring that user data is protected. The service offers end-to-end encryption, meaning that only the sender and recipient can read the messages, not even ProtonMail itself. The user interface is intuitive and accessible, making it suitable for both tech-savvy users and those new to encrypted communication. ProtonMail also provides features like self-destructing messages, customizable folders, and an option to send encrypted emails to non-ProtonMail users.
