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

Say goodbye to the big eavesdropping giants of electronic Mail

This app is brilliant,it makes me feel more relaxed and the paranoia of eavesdropping from Gmail and all their third parties sifting through my private life that includes all the other “Big Boys “ because having the comfort of encryption puts a bit of a smile on my face (it’s not that we have anything to hide) “it’s the principle of having your messages exposed to the world) but with Proton Mail you can relax, their customer service is second to none (I sent a message around 9am got a reply before midday),and although I’m only using the free version this is in itself is second to none - P/M puts all the others in the shade. If I could give it a 6 STAR I WOULD,HIGHLY RECOMMEND ⭐️⭐️⭐️⭐️⭐️

Good security but lacking features and bug support for a paid service

Been using the paid service along with their VPN for quite a while now, but have got to the point where I am now looking to migrate over to another service. It’s all well and good having good security but that needs to be backed up with equally good functionality and support. The app is less than overwhelming and is missing basic functionality like swiping to mark as read etc. since iOS 15 there have been a few bugs and my push notifications haven’t worked so I am constantly having to remember to open up the app and refresh it manually to check my emails….inevitability I have missed emails that were fairly important (not good). Tried all their fixes like emptying the cache, which work temporarily but this is a known issue and in my case has not been fixed in well over a month. It would be different if i wasn’t paying for a premium service, but I am and a fair amount considering. I have already downgraded the VPN and expect will migrate the email over to another more practicable, reliable service soon. Very disappointing!

A good product let down by poor recovery protocols

Proton is a great champion of internet privacy and has some good app products supporting this objective. This is a solid, no frills, encrypted email service which does everything it is supposed to do. However, it seems to be aimed at a tech-savvy market. For example, the app doesn't warn you that, if you reset your password, it has the effect of decrypting all your emails (making them unreadable) unless you then use the old password to reactivate the encryption keys. This is a bit silly tbh because most people will only want to reset their password if they've forgotten the previous one. To avoid this fate, you have to write everything down at least once and make a record of it, which somewhat defeats the privacy objective. Because of this flaw, I wouldn't want to be overly reliant on Proton for email functionality.

The inbox screen display is a bit dour but is fit for purpose. If they could make the screen view visually more appealing, the product overall would be more attractive.

Developer Response ,

Hi. Thank you for your feedback - we've shared it with our team. Please note that when requesting a password reset, a warning is prompted to the user that all the messages will be encrypted. This is due to protect the user's data in case of a case of compromised account. Due to the nature of our encryption, we do not have access to your password and the only way to decrypt your messages is by providing your old password, uploading your recovery file if you've downloaded it previously, or providing your recovery phrase.

We'll share your feedback regarding the app's interface so our team can work on improving it. If you have any specific suggestions on what we can do to improve, feel free to contact us at https://proton.me/support/contact to let us know.
