Description
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

Ratings and Reviews
Disappointing (proton mail subscription) - edited.
I missed the renewal date - yes, my bad, but I really wished Proton would’ve sent me a notice about upcoming charge to the credit card rather than sending me anniversary email and 1Gb storage for free. I really do not need such expensive service anymore and I was hoping for some sort of refund - but no real refund policy exists here, it’s in a form of credit towards future purchase which is rather unfair for someone wanting to move on. I have over 300 days of service left that I don’t need and I haven’t heard anything from their customer service so I have to assume it’s also non-existent.
Update: after posting here I’ve received prompt response from the developer and managed to get a refund processed. So it looks like every case is different and treated individually. I appreciate even belated response and being considerate towards getting money back rather than issuing credit for something one has no use for. Well done Proton.
Developer Response ,
Hello! We're sorry to hear about your experience. Please share your ticket number with us here so we can track your case internally and follow up on your request.
Improve UI/UX and add U2F support
To be honest. If you want money for your service and more customers, you must deliver a high quality product. From technical, UI and UX side. If we talk about technical side, you don’t still have U2F support. I would like to reminder it’s only way to protect against phishing. UI and UX of your app is really bad IMO. You don’t even have the conversation grouping feature in the mobile app. Your service isn’t cheap, so I don’t understand why there are so many fails in different domains. I will give you more stars and consider paying for your service if you add at least the conversation grouping feature and U2F support. I believe you can give more in UI and UX areas as well.
UPDATE (feedback for the developer’s answer):
Sure. I will give you more stars with pleasure if I find improvements. I will also appreciate when there are no limits in the plus plan such as limits in sending/receiving emails per day. There shouldn’t be any such limit if someone pay for the service imo. These things will encourage me to pay for your service, because you do a good job in the privacy area, and thank you for that, but at the moment both mentioned limits and your mobile app is not good enough to pay for it.
Developer Response ,
Hi! Thank you for your feedback. Many new features will come to the mobile apps with the 4.0 redesign on which we are currently working on. U2f is coming post 4.0 as that's a prerequisite for u2f. We would really appreciate it if you could reconsider your rating once these features are available.
Keep investing in security, waiting for Calendar/Drive on iOS
Happy to hear you engage Securitum to perform the security audit! Please continue ongoing investment in security of the apps and infrastructure.
I would prefer to get Calendar and Drive support on iOS instead of visual changes in the mail app (iOS or web beta) application (it looked very nice, clear and simple before the changes).
