Proton Mail: Encrypted Email APP Review

Proton Mail: Encrypted Email is a privacy-first email app hailing from Switzerland, designed to keep your conversations secure and away from prying eyes. Trusted by millions globally, Proton Mail offers end-to-end encryption that ensures only you and your recipient can read your messages. This app is perfect for anyone serious about email privacy without compromising on usability.

The Proton Mail app lets you create unique @proton.me or @protonmail.com email addresses and send encrypted emails and attachments effortlessly. You can manage multiple Proton Mail accounts, organize your inbox with folders and labels, and enjoy handy features like swipe gestures and dark mode. Security is top-notch with zero-access encryption architecture and strong defense against phishing, spam, and trackers.

What sets Proton Mail apart is its commitment to privacy and open-source transparency. Your emails are encrypted on your device before they reach Proton servers, so even Proton can't access your data. Its encryption libraries, vetted by security experts worldwide, guarantee no sneaky backdoors are present. The app is free to use with optional paid upgrades that give you more storage and features, supporting Proton's mission to protect your privacy.

While the app offers outstanding security and a clean interface, some users report occasional slowness, limited search capabilities compared to the web version, and minor usability quirks like attachment handling and text wrapping. Nonetheless, the Proton team actively addresses feedback and continuously improves the app's performance and features.

In summary, Proton Mail is an excellent choice for those who value email privacy, need strong encryption, and want a straightforward email experience without targeted ads or data harvesting. It’s ideal for individuals and businesses seeking a secure alternative to traditional email services.

Small unreadable font that can be changed only with global font size change for all apps. But every other application's font size is OK.

Developer Response

Thank you for your feedback! We've passed it along to the team so it can be taken into consideration for future improvements.

Wanted to like this and very glad there was a 99p trial service as I've found it's just not for me. Reloads can take ages or just don't end. Newly added folders don't update throughout the app, so I can't sort anything (it's been a week now in spite of refreshing cache, turning off VPN, etc). Was also hoping for categorisation features I've seen in Proton update schedules going back a few years, but can't see those available. I like Proton's service theoretically, but this isn't functional.

Version: 7.6.2

Developer Response

Thanks for giving Proton a try and for sharing this feedback—we’re sorry to hear about the trouble you’ve run into. If you haven’t already, please report this directly through the in-app 'Report a problem' option so our team can look into it with logs and device details. That will help us investigate.

Been using this email for years as a more business type email and its not only ran great but feels good to use, i have a sense of security. I'm no tech bro but from what i gather, i like what they're doing and that they aren't constantly mucking with the app like gmail does.
