Who it's for
Proton Mail is for users who prioritize strong email privacy and security above all else and are willing to tolerate significant app usability issues and potential data loss during password resets R3R5R8R13. It is not for users who expect a smooth, feature-rich, or highly responsive mobile email experience comparable to mainstream providers, or who rely on prompt customer support R2R14R20R21.
Evidence note: The recent reviews skew heavily negative regarding app functionality and user experience, which contrasts with the high lifetime rating. This suggests a recent decline in app quality or user satisfaction, possibly due to recent updates. Evidence for specific bugs and missing features is strong and consistent across many reviews.

- [R3] Excellent: I have been using proton mail for about 2 months and I am enjoying its privacy features a lot. I also pay for the 200 gb cloud storage and it is worth it. I highly recommend this app to everyone.
- [R5] Great Proton email: Love using Proton email: easy to use and safe 🩷💕
- [R8] It's on par with Proton's other offerings: I have very high expectations of Proton and I have yet to be disappointed. Thus I recommend all their products, especially their VPN service which I also use.
- [R13] Protonmail: I have used Proton Mail for business and feel confident and secure with my correspondence being safe...
- [R30] Flawless: The best part about having a Proton account is that I receive ZERO junk or spam emails.
- [R49] amazing privacy focused email: I personally love how it’s so user friendly and all the privacy features email forwarding was REALLY a lifesaver, thought it was going to be tortuous to transfer all my accounts, but any accounts I missed will just automatically forward! the subscription is pushed in your face a BIT in the beginning but not that bad, so I’m perfectly fine with it finally, the on
- [R2] Blank screen: App is completely broken. loads to a black screen.
- [R4] UI UX Improvements: Overall love the progress and the better mobile experience. Please continue to improve the UX and UI to give the user a more natural experience with navigation. Bug report: sometimes emails are hidden or don’t show up, and only 2 out of all unreads are show until you toggle when all email are supposed to show up.
- [R6] Bugs and suggestions: Bug 1 - pick a message then use three dots at bottom right then use Archive. Get feedback that message was archived but message stays in inbox Bug 2. - search seems hit or miss Works ok only when exact match of whole word is made Suggestion - make message Archive an option at bottom of screen as one touch option instead of having to click multiple times
- [R14] Was good: New version is unusable Enter id and password then locks up at " human verification "
- [R1] Great mail client: I only have a single issue with Proton Mail ,and all of the other Proton apps, functionality that is available through a browser,or a PC isn’t all available in the apps. Would be awesome if Proton developed an account/profile management app. Other than that it’s a fantastic mail app that just works.
- [R42] Good enough: Few of the main options are only able to be used in the web version. Not the app version
- [R21] Search Folder to Move Messages: Still no option to search folders when moving mails. Lazy! No option to search for folders when moving an email. Instead, I have to scroll, scroll, scroll 😤
- [R61] Why can’t I share contacts?: Why can’t I send emails bcc to over 100 people at a time? Why can’t I share contacts? Why is spell check of emails not available? Your IT group needs to up their game!
- [R20] Phenomenal product, suboptimal speeds: I love this service. I'm in the complicated process of de-Google-ing my life and Proton has been incredible so far. My only genuine complaint about their iOS Mail app is that my typing speeds plummet when composing an email in their composer. The keystrokes lag behind my fingers for full seconds; I have to write emails separately in a note, copy, and paste in
- [R58] Phenomenally slow!: I love Proton Mail for its security features, but I find it astonishing that a platform that is so good with security has such gigantic technical glitches in its app. When I get a notification that a new message has arrived, it usually takes 1-2 minutes for the message to load. Sometimes, the message doesn’t load at all. A recent description of the latest updates claimed thi
- [R71] Slow: I’m giving three stars cause it’s supposed to be secure but it’s taking a min to delete one email and you can’t even sort. I’d like to sort and delete 50 junk mails in 30 Sec. not keep waiting for it to catch up. Tried finding a link to ask support about this but just found unrelated faq. And I pay for this.
- [R121] Not as good as gmail: too many quirks to mention. one example is it literally takes sometimes 3-5 seconds to send an email like it’s running on a dial up modem. my internet is 1gig fiber too. i won’t pay unless its as good as gmail. your calendar is even worse. clunky. lacking.
- [R23] It can’t do basic things: After a major update this past winter, I believe, this app became a nightmare. It just can’t simply do the regular basic things like collapsing the quotes. I must scroll through the entire conversation to the next. It also opened the new response at the very bottom of the screen so I must scroll down to read the newest message. If it’s the newest and I just topped it, it
- [R60] The font size is too small: This review is more a feature request, I can’t zoom in on emails and with that most of them are too small to be read on a phone. Can you add an option to zoom in please? Or to display text with larger characters? [Update]: I used “Report a problem” button within the app to submit this.
- [R64] Good overall: I am happy so far except for mobile phone version. It doesn’t resize well. Sometimes the fonts are too small and when I tried to enlarge it, I do not see the full screen of the message content. It’s frustrating.
- [R18] Avoid Proton Mail…: They bait you with a basic free plan, so you start using your new email address, only for your storage to immediately become full after a few emails. At that point, you either have to pay or you can no longer send/receive emails & your new email address is now useless. This is by design and not a customer friendly experience. They’re basically trying to strong arm users usi
- [R62] Hmm: You only get 1 gb with free account and sometimes when websites ask me for verification codes proton takes forever to get them and sometimes it doesn’t . I’m deleting account
- [R24] shieet: What’s the point of having a customer support if you ain’t going to help 🤣 I’ll switch back to more reliable providers.
- [R35] Don’t loose your password: After using proton they themselves wanted me to change my password .. it’s not a simple process of just changing a password .. after 3 months of communication back and forth with proton .. I was finally ready or so I thought to change my password .. only to find out without a 12 word recovery phrase .. I was able to reset the password but in doing so the old account was
- [R36] Mobile App not working: Downloaded the mobile app. I already have a paid account. Could not login. Tried multiple times. Now locked out even after changing my password as requested. No customer support beyond sending a message with no expectation of a reply for at least 24 hours. DO BETTER!
- [R53] Deactivated for no reason: This email was deactivated, leaving me without access to social media discord and other logins. Reached out to Support and got no response.
- [R74] Incredible app but….: I’m not sure if I’m the only one who feels this way but whatever the reason is for making the app completely encrypt and lock you out of all previous emails and their contents when you have to reset your password is absolute insanity. I am guessing that it has something to do with keeping your account as secure as possible in a unprecedented way but it was absolutely heartbre
- [R41] Updated: I deleted the app and reinstalled as asked in the developer response and I was able to log in this time. I have not yet had a chance to use the app, but everything looks good. Now I just wish proton gave more time to complete the steps necessary to get the larger mailbox. I’ve had more pressing concerns to attend to than going through all the steps necessary to get the additional storag
- [R45] Scammers: Took my account for no reason I can’t even login to get my real estate certificate I tried to get my account back and they said they couldn’t confirm my identity
- [R130] Poor usability: Poor usability for the signup bonus to receive double the amount of free storage. You are put on the clock to complete a vague checklist of four tasks, but the checklist seems to be a figment of Proton’s imagination. You install the iOS app, read the promotion instructions, it tells you to sign in with the web app, and one of the steps is to install the iOS app. It’s a stupid hall
- [R43] Missing block sender feature: The block sender feature requires you to open phishing emails. “What’s new” Search does not work, matching text in body are not in search results They just made 1/3 of the page blank space. Need to add block sender to the checkbox menu When there’s a thread of emails, opening always lands on a random old email instead of the latest
