    Keep your conversations private. Proton Mail is encrypted email from Switzerland. Used by millions worldwide, our all-new email app protects your communications and has everything you need to easily manage your inbox.

    The Wall Street Journal says:
    “Proton Mail offers encrypted email, which makes it virtually impossible for anyone to read it except the sender and the recipient.”

    With the all-new Proton Mail app, you can:
    • Create a @proton.me or @protonmail.com email address
    • Send and receive encrypted emails and attachments with ease
    • Switch between multiple Proton Mail accounts
    • Easily manage your email with conversations
    • Keep your inbox tidy and clean with folders, labels and simple swipe-gestures
    • Receive new email notifications
    • Send Password-protected Emails to anyone
    • Enjoy your inbox in dark mode

    Why use Proton Mail?
    • Proton Mail is free — We believe everyone deserves privacy. Upgrade to a paid plan to get more done and support our mission.
    • Easy to use — Our all-new app has been redesigned to make it easier to read, organize, and write your emails.
    • Your inbox is yours — We don’t spy on your communications to show you targeted ads. Your inbox, your rules.
    • Rigorous encryption — Your entire inbox is secured, on all your devices. No one can read your emails but you. Proton is privacy, guaranteed by end-to-end and zero-access encryption.
    • Unmatched protection — We offer strong phishing, spam, and spying/tracking protection for all your communications.

    Industry Leading Security Features
    Messages are stored on Proton Mail servers using end-to-end encryption at all times and are transmitted securely between Proton servers and user devices. This largely eliminates the risk of message interception.

    Zero Access to Your Email Content
    Proton Mail's zero access architecture means that your data is encrypted in a way that makes it inaccessible to us. Data is encrypted on the client side using an encryption key that Proton does not have access to. This means we don't have the technical ability to decrypt your messages.

    Open-Source Cryptography
    Proton Mail's open-source software has been thoroughly vetted by security experts from around the world to ensure the highest levels of protection. Proton Mail only uses secure implementations of AES, RSA, along with OpenPGP, while all of the cryptographic libraries used are open source. By using open-source libraries, Proton Mail can guarantee that the encryption algorithms used do not have clandestinely built-in back doors.

    Proton Mail in the press:
    “Proton Mail is a Gmail-like email system which uses end-to-end encryption, making it impossible for outside parties to monitor.” Forbes

    “A new email service being developed by a group who met at MIT and CERN promises to bring secure, encrypted email to the masses and keep sensitive information away from prying eyes.” Huffington Post
