Proton Mail Opiniões 

I created an account.
I saved the details
The following day, I couldn’t access the account, even though I’d saved the details.
Forgot password, tried that, useless
Forgot username, tried that useless.
I gave up.

1 semaine d'attente et toujours aucune réponse à ma demande ... support et donc entreprise totalement inutile à mes besoin (cela prouve qu'il faut toujours tester la version gratuite avant) Ravi de ne pas avoir versé le moindre centime.

Not useless, i have just close my account!

Unlimited plan claims to have Priority support. That is a lie. I have waited days on end for replies to basic support tickets.

Their calendar sucks. The VPN is slow. Multiple outages with little to no communication to users.

Use Tuta or Infomaniak instead. Paid plans are not worth the money with Proton.

I am very happy there is a good alternative to Gmail, but they have some points of improvement.
I have the problem that the size of my font often changes in an e-mail. This can lead to clear misunderstandings, as all of A SUDDEN THE FONT BECOMES BIGGER. I know it happends when I copy-paste things, but even though I try to undo the changing font-size (e.g. by erasing the font or pasting things with shift-contrl.-v) it keeps happening. In Gmail I never had this problem. Hopefully they can help me. (I already reported the bug, but haven't got a working response or fix yet)

Dear Proton Mail,
I note your response today to the review I posted three days ago. I now have to waste further time publicly clarifying that you did not provide me with any ticket. What I received was a cursory, generic reply claiming a commitment to “joint working,” while simultaneously stating that you are “unable to check each older inquiry.” This contradiction is unacceptable, and your request that I “ask again” merely confirms that no meaningful review of my original issue has taken place.

My email account was deleted. All of my emails gone. No prior warning.

Absolutely unforgivable and the worst possible thing that could happen.

I will NEVER recommend Proton to anyone and will actively dissuade people from using the services.

Edit: What use is sending reminder emails *TO THE EMAIL ACCOUNT THAT IS NOT BEING SIGNED INTO*

Contacted their CEO, Mr. Andy Yen, and copied in customer service days ago. Nothing. I have another enquiry, but am wondering what is the point of contact if they can't be bothered to respond to the first email.

Even though I have a cheaper VPN and Storage Solution, the 'stated' security to ensure AI does not read all mails (like they say Google does ) appealed. I decided to try it before considering upgrades.. I realised when trying to import my GMAIL that I had an account already but could not remember anything about it (probably many years).. I reached out to Support and it's in the 5th day no reply. Definately not what anyone would expect from customer service and certainly no if you're asked to pay for it. It's a great example of poor service and losing potential clients

Sorry, proton but I’m deleting the account and you’re getting a one star review all because you are not user-friendly whatsoever goodbye.

ordered their "Unlimited" package, but quite disappointed. Many products are just low quality. For example. Their VPN app for windows needs more than 30 seconds to start (!!!). What is that? or their password manager. on windows it has fingerprint scanner, but on linux - it doesn't and you have to manually enter your password all the time. Very disappointed by their service.

„Dein Posteingang gehört dir“ – meiner wurde gelöscht und meine Adresse ist dauerhaft verloren

Ich habe Proton Mail gerade wegen des Datenschutzversprechens genutzt. Meine bisherige Erfahrung hat mein Vertrauen in den Dienst allerdings erheblich beschädigt.

Nach längerer Zeit wollte ich mich wieder in mein Proton-Postfach einloggen. Statt einer Erklärung bekam ich lediglich die Information, dass dieser Account nicht existiert. Erst durch eigene Recherche habe ich herausgefunden, dass mein Konto wegen Inaktivität gelöscht worden war.

Eine Benachrichtigung über die bevorstehende Löschung habe ich nicht erhalten. Ich hatte bewusst keine alternative E-Mail-Adresse hinterlegt. Gerade weil ich Proton aus Datenschutzgründen genutzt habe, wollte ich beispielsweise nicht, dass jemand mit Zugriff auf mein Gmail-Konto darüber herausfinden kann, dass ich zusätzlich eine Proton-Adresse besitze.

Dass ein kostenloses Konto nach längerer Inaktivität gelöscht werden kann, ist eine Sache. Besonders gravierend sind für mich jedoch die dauerhaften Folgen.

Meine Proton-Adresse war nämlich nicht irgendeine unwichtige Wegwerfadresse. Sie ist als E-Mail-Adresse bei einem meiner Bitcoin-Konten hinterlegt. Damit hat die Löschung Auswirkungen auf ein anderes, für mich wichtiges Konto.

Ich habe das Passwort meines ehemaligen Proton-Accounts weiterhin und habe wegen der Sache mehrfach per E-Mail mit Proton kommuniziert. Trotzdem kann der Account nicht reaktiviert werden. Auch die alte E-Mail-Adresse bekomme ich nicht zurück und sie wird nicht erneut vergeben.

Genau das kann ich nicht nachvollziehen. Ich möchte weder die Adresse eines anderen übernehmen noch einen fremden Account beanspruchen. Es geht um meinen eigenen ehemaligen Account, dessen Passwort ich noch besitze. Trotzdem ist die Adresse mit meinem gewählten Namen für mich dauerhaft verloren.

Hinzu kommt die für mich völlig unzureichende Kommunikation beim Login. Die Anwendung sagt lediglich, dass der Account nicht existiert. Dass er einmal existiert hat und wegen Inaktivität gelöscht wurde, musste ich selbst herausfinden.

Von einem Anbieter, dessen Image so stark auf Privatsphäre, Kontrolle über die eigenen Daten und Aussagen wie „Dein Posteingang gehört dir“ setzt, hätte ich etwas anderes erwartet.

Datenschutz bedeutet für mich nicht nur, dass Unbefugte meine E-Mails nicht lesen können. Dazu gehören für mich auch Kontrolle, Transparenz und die Gewissheit, dass ich rechtzeitig verstehe, wenn eine Entscheidung des Anbieters dauerhafte Konsequenzen für meine digitale Identität hat.

Mein Postfach ist weg. Meine persönliche Proton-Adresse ist dauerhaft weg. Und obwohl ich das Passwort noch habe und Proton mehrfach kontaktiert habe, gibt es keinen Weg zurück.

Für mich ist das ein äußerst bitterer Umgang mit einer Adresse, von der ich angenommen hatte, dass sie dauerhaft meine ist.

DO NOT USE PROTON MAIL!!! If you want your passwords hacked, your emails made inaccessible and to be randomly blocked from being able to send and receive emails then use Proton Mail. Proton Mail tell absolute lies about their security, I have never experienced such an unsecure email provider and that is as a paying customer to them. PROTON MAIL TELL LIES AND DO NOT PROTECT YOUR EMAILS AND DATA! DO NOT USE PROTON MAIL!!!

TOO MANY BREAKDOWNS - SERVICE INTERRUPTION - NO CUSTOMER SERVICE!!!

Avoid Proton. There are far too many service interruptions and NO customer service, NO human beings, and NO follow through.
They have constant service disruptions and NO help for the ongoing issues they seem to have.
AND IT GETS WORSE EVERY YEAR!!!!!
Proton used to be a good email provide, BUT they have lost all respect from this user.... ANYONE KNOW A GOOD REPLACEMENT? WE are READY TO CANCEL!

Ich nutze Proton Mail jetzt seit drei Monaten. Inzwischen ist es heute das dritte Mal, dass E-Mails erst mit einer Zeitverzögerung von über 20 Minuten ankommen. Das ist mehr als ärgerlich wenn man gerade auf einen Verifizierungscode wartet der in zehn Minuten bereits abläuft und so das Einloggen bei einem anderen Unternehmen unmöglich gemacht wird. Ich nutze hauptsächlich die App. Heute habe ich die Desktop-Version geöffnet, da die App nicht funktionierte und musste leider feststellen, dass lediglich E-Mails vom ersten Tag als ich Proton Mail nutzte, in der Desktop Version angezeigt wurden. Zudem wurde mir angezeigt, dass ich angeblich nur die Free Version hätte, obwohl ich vor drei Monaten ein Jahr im Voraus bezahlt hatte. Ich denke, die viele Werbung des Unternehmens hat viele Neukunden gebracht und das hat zu einer permanenten Überlastung des Systems serverseitig geführt. Schade um mein bereits bezahltes Geld aber ein E-Mail Provider der nicht erreichbar ist, bringt ja außer einem Haufen Ärger nichts. Ich werde meinen Account sofort wieder kündigen (sobald das technisch irgendwann wieder möglich sein wird).

How about a mail provider who blocks legitimate content from reaching you, and telling you that it is for your own protection, even after you whitelist the sender? Think the analogy of that in terms of governments? Do you want that? This is not a provider anyone should ever want to have.

Mein Account wurde ohne Warnung gelöscht und kann nicht reaktiviert werden. Klar, Identitätsdiebstahl ist ein Problem, aber wenn der Account reaktiviert würde, könnte ich mit meinem Passwort wieder einloggen. Also, wo ist das Problem. Mein Rat: Finger weg! Sucht einen anderen Dienst!

Proton gibt dazu immer dieselbe Erklärung ab. Völlig nutzlos. Ich bleibe dabei: Finger weg von Proton!

J'utilise ProtonMail depuis une bonne dizaine d'années, d'ailleurs ma première adresse était .ch, en version gratuite d'abord et maintenant en version payante. J'utilise toute la suite Proton, mail, drive, pass, SimpleLogin, Standard Notes, authenticator. J'apprécie la confidentialité, le respect de la vie privée : à l'ouverture d'un mail, les pixels sont bloqués, ce qui fait que l'expéditeur n'aura pas l'info que le mail a été lu, et tant d'autres avantages. Il y a ici beaucoup d'avis négatifs. Personnellement, je ne rencontre pas les problèmes énoncés, un e-mail en anglais ? Il suffit de clic droit et traduire; mais bon. Je recommande Proton à ceux qui recherche la sécurité.

While the support representatives were polite, the supercilious attitude was obvious in their communications (i.e., proton is always right). Support did nothing to resolve the issues with their email system, and denied any responsibility for what had occurred. Support missed the main point of my communications numerous times, and I had to clarify it for them. Even then, they denied that what I claimed happened had indeed happened. At they very least they should have thanked me for the information I provided, which demonstrated that their are some problems with their email system. I'm sure this review will receive a response from proton, asking me to contact them. I won't be doing that, as I've already wasted way too much time on this, and proton couldn't / wouldn't previously resolve the situation. In short: great product, if you don't need support.

I chose Proton Unlimited mainly because Proton is one of the very few providers whose technical architecture genuinely implement the level of security and privacy it publicly claims to provide. From that point of view, I still consider Proton one of the strongest services available.

Unfortunately, my experience with Proton Mail and Proton Drive has not been equally positive in terms of reliability and synchronization.

With Proton Mail, I found the folder hierarchy too limited for my needs. I also experienced inconsistencies between the mailbox structure shown on mobile, on the web interface, and in Thunderbird through Proton Mail Bridge. During migration from an old Gmail account, several messages ended up in a recovery folder and generated errors.

After resetting Proton Mail Bridge, some messages disappeared from the local folder structure, leaving me uncertain whether they were lost, still present on Proton’s servers, inaccessible from the client, or only available in the original Gmail account.

Bridge synchronization was also quite slow.

Proton Drive was more concerning for me. Normal synchronization was reasonably fast, but making files available offline could become extremely slow, sometimes around one file every 30 seconds for ordinary photos and documents. I also observed situations where the application reported that synchronization was complete while files still appeared to be waiting for upload or download, and in some cases newly created files did not appear online as expected.

I understand that end-to-end encryption requires additional processing, and I appreciate the security model. However, my archive contains thousands of files and my mailbox contains thousands of emails accumulated over many years. For this kind of use, I need to be able to trust the synchronization state without continuously checking whether every file and message has actually been transferred correctly.

I eventually decided to cancel Proton Unlimited and migrate my files and emails back to Dropbox and Gmail. I am now restoring recent backups and comparing folders and messages to make sure nothing has been lost, which is a substantial amount of additional work.

This is a real pity because Proton’s privacy and security model is one of the best reasons to choose the service. In my experience, however, the desktop applications, Proton Mail Bridge, and synchronization reliability are not yet at the same level as the underlying security architecture.

I hope Proton continues improving these areas, because if reliability and synchronization become as strong as the privacy model, the suite could be outstanding.

No refund for the "unlimited plan" after the legal period expiration.

20260907 : ticket 5127571

It's impossible to get any meaningful help or customer support for Proton mail. I just subscribed to their Proton Plus yearly plan, and, due to a trivial billing issue, my active account, with important, time-sensitive communications, has been locked out. There is NO WAY to actually interact with a living human being. Everything is run by Zendesk on the other end and a useless AI tool in the user interface, which I was only able to access because I have another free Proton account. There is a fillable form -which I've used multiple times- that only opens up yet another new ticket for the same problem- with no resolution. This is a circular nightmare from hell without resolution!

There is no such thing as 24/7 support as they claim! It's been 3 days, multiple email attempts, and escalations to get help at resolving a trivial billing issue, and we're still at square one. If they had even one live agent for basic customer support, it would solve everything. The "live agent" feature advertised as available with their Customer Support AI tool doesn't actually exist. When selecting that option, they default to an email contact - live agents for Proton mail customer support don't exist at all, in any form, contrary to their advertised hype.

Update (9/3/2026): Proton finally restored access and I am grateful for that. Considering that all other, major mail service platforms are now requiring 2FA, a veritable nightmare if you don't have another device with you, I am going to primarily use Proton and my Mailfence accounts because THEY DON'T USE IT!

Public service announcement: don't use any mail service platform that requires 2FA when traveling. If all you have with you is your laptop and no other device, you may be locked out and cannot access your mail. This is why, when access really matters, I will always use Proton or Mailfence from this day forward.
