Proton Mail レビュー 

J’ai utilisé Proton mail pendant quelques mois et j’étais ravie. Version un peu payante avec mail +. Et puis arrivé le renouvellement, gros cafouillage ! Je n’ai rien compris : une version soit disant mensuelle que l’on doit payer immédiatement pour l’année ! Bizarre, et en retour de paiement une notification indiquant que je viens de payer 0€ …. Incompréhensible et pas moyen d’avoir des infos dans la langue de Molière 😱. Je viens de partir à mon grand regret, j’ai récupéré mes mails pour les transférer vers une autre boîte mail. S’ils veulent des clients français il faut parler français ou bien donner une possibilité de traduction automatique. Je suis très déçue par cette expérience !

Lost my device and couldn't locate the password I used for the account so I did a password reset. now my old emails are encrypted and because the recovery methods are "use a prior device or remember your old password or upload a recovery key/file" i now cannot access my old emails. these are not regular person methods of recovery. if you're looking for user friendly, Proton ain't it.

Avoid this company like the plague, they completely ignore your UK Statutory rights, if you complain they never read the complaint just blindly state their company policy, even though it’s illegal. Currently disputing with my bank, hope they charge them an enormous chargeback fee. AVOID! AVOID! AVOID!

J'utilise la version gratuite et je trouve ce service mail super. Juste dommage qu'un vieux "envoyé depuis protonmail" se glisse a chaque fois que je souhaite envoyer un email.

Originally, I chose ProtonMail because of its FOSS web client, sieve support, the capability to contact support personnel, and that its UserVoice instance provided a way to vote on feature requests.

I intend to leave Proton Mail, because I see no way to acquire server-side IMAP credentials, for AOSP e-mail clients, which I require, to respond to mail on Proton's servers, via different providers. Bridge may provide this for desktop OSes, but that's useless 50 % of the time, because I'm not always at a laptop.

Although I don't utilise their other services, this is also true for Contacts and Calendar, which offer no CardDAV or CalDAV.

Additionally, their ZenDesk instance's web interface has been disabled, rendering accessing ticket information incredibly difficult without e-mail account access.

Pro:
- Mail is securely encrypted end-to-end.

- Incredible good customer service that replies to mail mostly within 24 hours. In my case, the replies are always clear and straight to the point.

Cons:
- Can only be used with Proton Mail. No import feature of other mail accounts.
Only emails from your other mail accounts can be imported, but not the accounts themselves.
So, users need to make a new Proton Mail account and inform all users of their current mail account of their new Proton Mail account.
If possible with your former mail accounts, you could automatically forward all email to your new Proton Mail account.
With internet accounts of companies, private data can be updated by the account holders themselves, but for others it depends on the people and companies themselves whether they change the new mail address with the old one in their database.
Hence, if people change to Proton Mail and automatically forwarding isn't possible, they still have to check their previous mail app on a daily basis for a long time because we don't know who still has our old mail address. What if someone wants to contact us after many years? We wouldn't receive their mail because we switched to Proton Mail.
If automatically forwarding is possible, we still have to keep the subscription with the previous email account and should never unsubscribe. Otherwise we would miss email.
Suppose people use Yahoo Mail or other paid accounts. They have to pay the subscription for many years to come if they want to receive emails sent to their previous mail account.
Of course, this doesn't work and doesn't make sense either. Why should we throw away our current default mail address?
This is asking for problems!
Even if Proton Mail is more secure than the former mail, it doesn't make sense to delete that account!

- The Proton Mail app only supports two subfolders of each folder. A third subfolder isn't possible.
Eg. Study (main folder) - name of institution (subfolder 1) - name of department (subfolder 2). That's it.
For sure, you want to list subfolders of 'name of department' with people's names and other information.
This is also asking for problems because it's normal to organize mail in subfolders, especially for companies.

- Secure mail sounds fine but is end-to-end encryption really important for mainstream users?
Cloud storage should be end-to-end encrypted, but email???
If we read the negative feedback it's clear that many people still don't understand the importance of 2FA and passkey security.
If people lose the key, there's no way to get into the account. It will be locked for always.
Proton has end-to-end encryption by default for its mail. But, I'm pretty sure that most people don't know the cons of end-to-end encryption. That's that they lose access if they lose the key!
End-to-end encryption of mail is only important for business users but not for mainstream users.
Currently, Microsoft is in the spotlight for closing accounts on request of the US government. This has nothing to do with end-to-end encryption but with government legislation.
So, it's much more important that users can be certain that their mail accounts won't be closed by the company.
Closing on request of certain governments is only applicable to certain business users.
In this regard, I see end-to-end encryption of mail accounts for mainstream users more of a marketing strategy than a real need.
The danger of losing the 2FA key or passkey is more important than end-to-end encryption.
I would advice to use email from a company which would't close your mail account if you haven't used it for a certain period and that doesn't has the danger of losing the access key.

To summarize:
Don't be too focused on end-to-end encryption of mail accounts unless you need it for your business and you understand the danger of losing the access key!
Concerning the Proton Mail app it's strange that such a well-known and reputable company has such a bad mail app.
The omissions of this mail app are not something nobody needs but default features that already existed 25 years ago with free mail accounts and free mail apps.

I have had an email with proton for 2 years which cost me a small fortune. Somehow my password was changed and I couldn’t log in to my account. After sending proton multiple emails with proof of my account they wanted me to send them my credit card details from an unsecured gmail account to which I refused so I now cannot access my account AT ALL ANYMORE!!! What a waste of money !!! I DO NOT RECOMMEND THIS PROTON MAIL AT ALL

I have reason to believe that half $1 million has been stolen from my interactive brokers account. I’ve been locked out of Proton Mail which is an email. I had to align with interactive brokers because Google had locked me out of my Gmail. I believe that Google and Apple have then prevented me from accessing my Proton Mail and I believe that Proton Mail has not gone out of its way to help me. My proton. Apple ID is still secure but of course the Gmail which is the one tied to interactive brokers was let loose from my devices. It doesn’t appear under my Apple ID. Interactive brokers is exactly named because for mind they are interactive and that anyone can access your account that $500,000 of ungeared money better be there I received in total $1.6 million at the start of 2025 most of it’s been stolen now I’m a form of police officer for the New South Wales police registered number 30954 and also the Australian federal police AGS13413 in 2012. I took in a transgender 23 year-old who won the queen of the night the following year with Victoria Martin was and is if she’s not dead hearing impaired she won the queen of the night and was selling her garments after I allowed her to complete her sewing course in fashion I facilitated that by helping her out she just lost her father in a car accident. But it was my money hungry ex-wife who I left in 2010 after uncle was accused of a trip by murder and convicted. She stated ties to the mob. I think it might be true because of 2017. It triggered the deaths of my parents who both died in 2023 I had an apprehended violence order taken out of me simply because I had taken in a transgender person who was hearing impaired. No allegation was put to me. My father was a bail court magistrate and issued apprehend violence orders during the week for Western Sydney opportunities retirement 2007 Kevin Andrew Dover born 19th of March 1944. This triggered their deaths in 2023 trigger after trigger after trigger. My death is what they want now and my health is terrible. I need to get to a hospital, but I’m shunned by all of the society in Australia and my brother will he had a brain injury at 10 months under the corrupt NDIS and there are four or five Solicitors aligned against us a big Bank and a broken notice the dark arm.

Do not use THEY ERASE EVERYTHING without consent and without informing you. So I went to check on my mail, even though I had not gone on they can see regular mail coming through. But because I have not gone and physically opened it in the app. I go there today to find a receipt to a message stating due to inactivity we have erased everything. This has to be the worse email service I have ever came across. I DO NOT RECOMMEND.

1. I discovered that Proton wasn't trusted by the Review site I used. I was allocated a reward for having done a lot of online reviews. But it took 8 months to get it paid. The payments were cancelled 7 times. When I asked about this the review site said that their integrity checking wasn't happy with claims coming from Proton email accounts. When I claimed through a different email provider the reward was paid in a couple of weeks.
2. I use Proton Free at the moment. I started to get messages that my mail box was full. So I deleted various things. I got the total down to an acceptable limit, so I thought. But overnight my total jumped to a level higher than it was before. I contacted the Proton help people and they suggested other places to look for things to delete. I did as they suggested. The total has now dropped to a very low level. But I have now lost data which I would have preferred to keep. I feel the false high memory signal was meant to prompt me to sign up for a paying account. I am very disappointed.
3. I contacted their help people and they said my messages weren't completely lost because they had a mechanism to retrieve them. They agreed to do so and later emailed that they had done so. They didn't retrieve them so I guess that's 200M gone.
Update
Just got response on here to provide ticket number publicly. I don't think that's an appropriate suggestion.

After 3 days, this was the ridiculous reply I got from support.

They claimed my account was “directly connected” to another account that violated their terms and was used maliciously. The problem is: they never explained what exactly I supposedly did wrong.

I only used my account to send legitimate emails to a business partner regarding motorcycle spare parts offers. That’s it.

No spam, no fraud, no malicious activity, just normal business communication.

Instead of providing actual evidence or clarification, they permanently suspended my account and said they were doing it to “avoid further damage to their service.”

The irony is that they are damaging their own service by randomly suspending paying customers without proper explanation.

Very frustrating experience. Be careful if you rely on this email provider for important business or personal communication.

I had the same problem and it was extremely frustrating.

I even paid for a subscription, and when I tried to log in, I got this message:

Dieses Konto ist aufgrund eines möglichen Verstoßes gegen die Richtlinien gesperrt. Wenn du glaubst, dass dies ein Fehler ist, kontaktiere uns bitte unter //proton. me/ support/ appeal-abuse.

I contacted support immediately, but never received any response.

Losing access to a paid email account without clear explanation or proper customer support is unacceptable. If you use this provider for important emails or personal data, be careful and make sure you have backups of everything.

Based on my experience, I felt completely let down and would not recommend this service. I saw on YouTube that the owner is a rich kid from China—that explains everything... They also check your emails and read all your messages! They claim it's secure, but they are very dangerous.

Absolutely horrible service.

Was recommended this as it was supposed to be secure and it would keep your things save.

I made several accounts. I didn't check on them for years as they were for other services. I recently checked on them, and sure enough proton deleted all of the mails.

Two more recent acccounts I had made weren't deleted, but proton had deleted every single mail in them "to keep them safe". What a horrible disgusting service.

If I had known what I was going into with Proton Mail so I had stayed away. I do not want to touch Proton Mail with a fire poker, and would recommend anyone even slightly considerating proton as an option to also think twice.

I think the icing on the cake was Proton support recommended to use paid subscription services to keep the account active. You know who also keeps your account active and for free permanently? Yahoo, for free. FREE.

It's just disgusting when companies tries to squeeze money out of consumers by providing a less than medicore service.

Proton Mail has been a very disappointing experience for me. My account was suspended after someone reported my email address. The strange part is that the report was made by a friend during a personal conflict, and we are now on good terms again, which makes the whole situation even more frustrating.

Despite this, Proton suspended my account without giving me a clear explanation or meaningful support response. I was unable to recover important contacts and data.

For a service that promotes privacy and reliability, I expected much better customer support and proper account recovery options. Other major email providers usually allow users to export contacts or recover important information before permanently closing an account.

I also paid for a yearly subscription, but my account was suspended shortly afterward and I did not receive a refund.

Overall, I feel this platform lacks transparency and proper customer support. Based on my experience, I would not recommend paying for a subscription.

I created my Proton Mail account a few months ago and also paid for the Mail Plus subscription. I mainly used the email for selling some items on Quoka and communicating with clients.

Yesterday, my account was suddenly suspended without any clear explanation. I honestly do not understand the reason. I contacted the abuse support team immediately, but I never received any response.

Because of this, I lost access to all my clients, contacts, and important conversations. I feel completely disappointed and frustrated. The system is very unreliable, and when something happens, you can lose everything without warning.

I expected Proton Mail to be a serious and professional email provider, but my experience has been the opposite. At the moment, I feel scammed and cannot recommend this service to others.

Ich habe gerade gesehen, dass Sie bei über 2000 Bewertungen nur 2 Sterne haben – das ist wirklich beschämend und erklärt meine Erfahrung leider sehr gut.

Sie haben mein Geld genommen, mein Konto gesperrt und mir den Zugriff auf wichtige Kontakte und E-Mails entzogen. Dadurch habe ich erhebliche Probleme in meinem beruflichen Alltag bekommen.

Ein solcher Umgang mit zahlenden Kunden ist absolut inakzeptabel. Ich werde meine Erfahrungen weiterhin öffentlich teilen, damit andere Nutzer vorsichtig sind, bevor sie Ihren Service nutzen.

Ich wünsche Ihnen viel Erfolg – schlechter als dieser Service kann es kaum noch werden.

Meine Erfahrung mit Proton Mail war äußerst enttäuschend. Nachdem ich für den Service bezahlt hatte, wurde mein Konto plötzlich ohne klare Begründung gesperrt. Dadurch habe ich den Zugriff auf wichtige E-Mails, Kontakte und geschäftliche Informationen verloren.

Besonders frustrierend war, dass der Kundensupport keine wirkliche Hilfe angeboten hat und es auch keine klare Lösung bezüglich meiner Daten oder einer Rückerstattung gab.

Wer E-Mails für geschäftliche oder wichtige private Kommunikation nutzt, sollte sich gut überlegen, ob dieser Anbieter zuverlässig genug ist. Aufgrund meiner Erfahrung kann ich Proton Mail leider nicht empfehlen.

Re: Ich bin an Ihren Dienstleistungen nicht mehr interessiert. Mein Konto wurde bereits ohne einen klaren Nachweis und ohne vorherige Benachrichtigung gelöscht bzw. gesperrt. Trotz meiner Kontaktaufnahme habe ich keine hilfreiche Antwort erhalten.

Ich nutze inzwischen einen anderen Anbieter, bei dem meine Daten sicher sind und ich keinen Verlust meiner Informationen befürchten muss.

Proton Mail has been one of the worst email services I’ve used. The technology and overall user experience are very poor. After paying for a subscription, my account was suspended without proper explanation, and I did not receive a refund or access to my contacts and data. Customer support was not helpful in resolving the issue.

Based on my experience, I cannot recommend this provider. Be careful before relying on this service for important communications or data.

Sorry, but I have already moved to another provider and I am no longer using your services.

I was disappointed with how the situation was handled, and I lost valuable time due to the lack of communication and delayed response.

Thank you for understanding.

Update May 15, 2026

See what these scammers do? Do they even read people's reviews?

They ask for a support ticket! When I explicitly said that after we wrote to their support, we received no confirmation and no ticket at all!

To Proton: you are scammers, you took over our business email, and we will sue the hell out of you. You will pay a lot for what you did.
~~~~~~~~~~~~~~~~~~~~~~~~

Proton.me is a fraud. There is no doubt about it.

We had a professional-sounding email address for secure communication with high-profile clients globally. We are a European company. Then, suddenly, one day, we lost access to our email.

We submitted a complaint through Proton’s contact form, but received no confirmation and no support ticket.

We then contacted Proton directly at their abuse email address and received a standard reply about a supposed policy violation. We asked them to clarify what happened and why our access had been blocked, but they gave us no further explanation.

We have not violated Proton’s policies in any way. Our email was used strictly for business communication.

This was a fraudulent email takeover by Proton in order to access our communications.

Proton is a scam. Do not trust them, and under no circumstances should you use their services for serious business.

I have screenshots of:

- the failed email login attempt
- the request submitted to Proton through their contact form
- the email sent directly to their email address
- their standard reply
- our second letter to them
- the absence of any further response from Proton
