Opção segura para os e-mails mais populares

Não oferece algumas funções mais avançadas como os serviços mais populares, mas ainda sim é uma ótima opção para um e-mail seguro e fora do alcance de interferências de governos estrangeiros.

Poderia ter uma função para apagar múltiplas mensagens de maneira ágil.

Thank you for your 4-star review and feedback! We've passed it along to the team. Edit: You can select up to 100 messages in the iOS app and delete them. Nevertheless, we'll pass along your feedback to the team.

needs more functionality

switched to proton. don’t have an issue with the web version but the phone and ipad apps lack in customisation and could be way better designed . ipad app is not even worth using . can we please have the ability to remove sender images. keep up the good work.

Poor code quality

How many times does a paying customer have to turn off Proton’s signature line after updating? Seriously.

Repeatedly calling it a bug or code regression after a while suggests simply Proton can’t manage creating quality code.

If that’s the case, then it means the privacy and security promises Proton makes might not be so airtight.

Broken

App will not run on iOS. Also, in what decade will we be getting a true dark mode for the web browser version?

Overheating My Phone

Look, I love the service, but the last update has brought back some behavior that just chews through my battery and overheats my phone.

It was there earlier this year, then it went away, but now it’s back. I can be using apps that melt my phone, you guys.

連絡先画像/ユーザーアイコンが反映されない

1: Proton内で連絡先に設定している画像/ユーザーアイコンが反映されない (公式メール以外アルファベット1文字の淡白なアイコンで視認性もデザインも最悪)

2: それらを編集するにはWeb版からしかできない

3: Web版から編集してもiOS版アプリ上では現状表示されない

ーーー

まだベータテストなのかな???数年後にまた見にきます。あと機能が出揃ってない割に機能紹介メールが鬼のように届きます。「お前がスパムじゃ」と言いたいところですが、まあこれはそのうち収まるのでしょうね。ユーザーアイコンの件、サービス利用の断念を決定するほどの致命傷なので、早急になんとかしてください!!!

Hi. Thank you for sharing your feedback with us. We do have an existing request for the ability to add profile pictures for your contacts, and we'll note your +1 to help the team prioritize future improvements.

Unread was fine where it was

I am unfortunately not a fan of this new UI update, and I instantly opted to keep my inbox as is. Even so, there are minor but annoying permanent changes that I don’t like. Offering these as granular/customizable options would’ve been much better. It’s a small thing, but please implement top/bottom
options for the Unread button placement. Not everyone uses their phone the same way and, for me, the new placement achieves the opposite of its intended effect.

Love Love Love Proton

Easily the one company I hold the highest level of trust with. Been using their VPN for years (and I’m not one to pay for subscriptions). Mail has been something I’ve used much less but always for the highly sensitive things. Great app, great services, amazing company. Until Switzerland agrees to bend over on their privacy laws, Proton is the cats pajamas for all of your needs.

**update: forgot to mention that the ability to change the app icon to something more inconspicuous is a great feature. But the name should either change with it to match the photo, just be changed to “Proton” (or something), or allow users to create a custom name. Otherwise a calculator app with the name “proton mail” draws more attention than the regular icon.

Great mail, Two Small Improvements

I’ve been a longtime Proton Mail user and overall I really like it.
there are two small improvements I think would make the experience noticeably better.
1. Add a discreet mail icon
The “Discreet app icon” feature is a great idea, but the current alternatives are Weather, Notes, and Calculator. It would be much more useful to have an actual discreet mail icon as an option, similar to the Apple Mail icon. I’d prefer to keep the app looking like a mail app rather than disguising it as a completely different type of app. Apple mail icon would be perfect disguise.
2. Make “Sync with system” the default on the web version
When opening Proton Mail in a new/private browser tab for the first time, it defaults to Light mode even when the computer is already using Dark mode. You can manually switch it to “Auto-Sync with system,” but I think that should simply be the default behavior.
This is especially noticeable when I log in through a private window at night while my computer is already in Dark mode. It’s a small detail, but having Proton auto follow the system appearance would make the experience feel much more seamless.
These are both relatively small changes, but they would make an already excellent service noticeably better.

A simplified alternative

Trying this out as an alternative to my other cluttered email. So far, so good.

Leave out the AI

Don’t you hate when you open your email and have to click click click clear a bunch of dickover messages informing you that AI features have been enabled without consent? I do! I hate it! Leave that google nonsense at the curb or I’ll find a new email service to pay for.

After a year and updates

I was upset because the app use to send some data that was tracking your connection but not anymore. After a year on the basic plan it was a good investment. I have seen the changes to the app and it has not sent any data that exposes the connection. That is without a vpn so it may have but not recently. I have one email address left to create on my tier and decided to re-review it the app again. I’m having a better experience now and it is getting better. Love the pure email experience with no account sync even if it asks to link with my google account. If you don’t want to use or invest in the apple, google, and email sync then you should have this app. With games services linking more and more this app will help it stop. Just be aware you lose your account you lose the email but there are enough recovery options to avoid it. Thanks for removing the random telemetry data from the app so it can be used on my mac. Now I’m happy with this next step is replacing my social media email with a private paid version.

Response from developer

Thanks for taking the time to update your review! We're glad to hear your experience with Proton Mail has improved and that you're enjoying the privacy-focused email experience. We appreciate your continued support and your feedback as the app continues to evolve.

Proton Mail is becoming more like Gmail every day.

Ever since Gmail became untrustworthy, the one thing I have learned is that we will never again be able to have a “forever“ email provider.

At some point, Proton will become unusable. But I will be much better prepared to switch.

Family Sharing

The app is always improving but still need webmail for advanced features. HTML email is problematic.

App store support to manage family downloads isn’t enabled on Proton apps. Would like to be able to approve/deny what kids download.

Continued degradation of the UI

20 Aug 2026 pt 2:

Stick a fork in it folks. She's done. Used to be that the unread message count badge would fix itself after you refreshed the mailbox. No longer. Now the app badge is stuck with the wrong number of unread messages permanently. So Proton is not just ignoring bugs they are doubling down on them and making things worse.

20 Aug 2026

Why is a privacy forward app scouring my messages to needlessly categorize them???

Even better you've clobbered even more of the bottom row of the inbox list with a badge for the unread count. Who thought that was a good idea? Just show me my messages without covering them up with needless dreck. Before some genius decided that white space was more important than content the unread messages count lived out of the way. As a paying customer all I can do is beg Proton to stop updating the UI — you're making it worse with each update.

Since fixing actual bugs is not a priority they could at least spend time testing their awful app on a smaller phone. It's barely usable on an iPhone SE, not because of some technical limitation just because of poor design choices.

15 Apr 2026: yep. App badge still broken.

Want to see how many unread messages you have? Tough! You will get an approximation and you will like it!

Did you think that the app badge would accurately reflect the number of unread messages? Tough. You will get a random number generator and you will be thankful. It's not like you pay for this service.

Want privacy? Tough! We will load privacy violating icons because they're pretty and you can't turn them off because you will
love them!

Important Features not developed

We need better and more accessible organizational features, sorting, pinning, filtering, labeling.

Offline mode does not work

The app does not download images in emails. I have plenty of phone space and the latest version… Spent 30 mins w their Lumo chatbot and got nowhere. In the end - no offline mode, you may lose access to you email content. Do not rely on it.

Peace of mind!

Peace of mind knowing my coms are secure.
