Proton Mail's all-new encrypted 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 • 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 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. 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 Easy Switch Migrate from Gmail, Outlook, Yahoo, iCloud Mail or AOL to Proton Mail in just a few taps. Your messages, calendars and contacts are transferred automatically, so you’re up‑and‑running in moments—without any manual exporting or importing. Gmail Auto‑forwarding Enable auto‑forwarding from any number of Gmail accounts and funnel all the emails that matter into your Proton Mail inbox. Preserve Gmail’s convenience while adding an extra layer of privacy protection. Proton Mail in the press: “Proton Mail is an 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 from MIT that met at CERN promises to bring secure, encrypted email to the masses and keep sensitive information away from prying eyes.” Huffington Post Follow Proton on social media for all the latest news and offers: Facebook: /proton Twitter: @protonprivacy Reddit: /protonmail Instagram: /protonprivacy For more information, visit: https://proton.me/mail Our open-source code base: https://github.com/ProtonMail}

It won't let me sign in. It keeps saying no address when I have the correct email address and password. So the login is broken, making the app worthless.

I use it because I hate having Google spy on everything I do, not because the app is better than Gmail 😞 It's mostly functional and decent UX, but there are always little glitches that drive me nuts.

Since the recent app overhaul, I can't use the app anymore. Can't open unread message, the app also stuck and doesn't load anything. Really frustrating

They claim ultimate privacy but they monitor your emails and even restrict certain emails from making it to your inbox. They then force verification or a plan upgrade.

Für ein webbasiertes E-mailprogr gut, da ohne Idiotennachrichten und Endloswerbung a la Web.de gmx &Co. dabei. Die kostenlose Version macht löschen vieler alter E-mails mühsam. Sonst alles OK. In China kann nur mit VPN zugegriffen werden obwohl andere E-mail Programme wie Thunderbird problemlos ohne VPN funktionieren.
