ProtonMail is an encrypted email service that takes a radically different approach to email security.

In 2014 the Swiss company ProtonMail became the first email service to protect data with end-to-end encryption, and today is one of the most popular secure email services.

The idea behind ProtonMail is only you have access to your inbox - this means no advertisers, governments, ProtonMail themselves or third parties gaining access to your data. ProtonMail ensures your private communications stay private.

ProtonMail is incorporated in Switzerland, which means all user data is protected by strict Swiss privacy laws.


Here are the central ProtonMail privacy and security features:

  • End-to-end encryption
  • Based in Switzerland with some of the strictest privacy laws
  • Stores your data in secure data centers

When setting-up an account ProtonMail will ask you for the usual username and password. There will also be a separate inbox password used to encrypt your inbox data. The service includes two factor authentication and a free ProtonVPN account.

ProtonMail use end-to-end encryption and zero access encryption to secure your emails. This means even ProtonMail themselves can’t decrypt and read your messages. As a result, your encrypted emails cannot be shared with third parties, such as advertisers .


Each ProtonMail account includes access to a free ProtonVPN account. This service enables private and secure internet access through their Virtual Private Network of intermediary servers. It means that you’re not browsing the web directly but through the guise of an IP address of one of their servers.

Encrypted Email

ProtonMail also allows users to send end-to-end encrypted emails to non-ProtonMail users. This works by sending a link to the recipient which loads an encrypted message onto their browser. The recipient will then be able to decrypt your email using a passphrase you can share with them.
