Features and specs

What each product offers, as listed by its team.

ProtonMail 5 features
Context Data 0 features
  • End-to-End Encryption
    ProtonMail uses robust end-to-end encryption, ensuring that only the sender and the recipient can read the emails. This enhances the security and privacy of your communications.
  • Zero Access to User Data
    ProtonMail does not have access to user data or emails. This means that even ProtonMail cannot read your emails, providing an additional layer of privacy.
  • Swiss Privacy Laws
    Based in Switzerland, ProtonMail benefits from stringent Swiss privacy laws, which are some of the strongest in the world. This offers users greater legal protection against mass surveillance.
  • Open Source
    ProtonMail's encryption algorithms are open source, which means their code can be reviewed and audited by anyone, promoting transparency and trust.
  • User-Friendly Interface
    ProtonMail offers an intuitive and clean user interface, making it easy for users to manage their emails efficiently.

Possible disadvantages

  • Limited Free Storage
    The free version of ProtonMail offers only 500 MB of storage, which might be insufficient for users who need to store a large number of emails.
  • Paid Plans
    Advanced features and additional storage require a paid subscription, which may be a hassle for users looking for a completely free service.
  • Search Limitations
    Due to end-to-end encryption, the search functionality in ProtonMail is limited compared to other email services, as the search can only be performed on email subjects, not the content.
  • Compatibility Issues
    ProtonMail's encryption might not be fully compatible with other email services, potentially causing issues with sending and receiving encrypted messages.
  • Learning Curve
    New users who are unfamiliar with encryption concepts might find it slightly challenging to understand and use all of ProtonMail’s security features effectively.
