Proton Mail Arvostelua 

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

Des voleurs et des escros de la pire espèce.
Vous annulée votre abonnement, derrière sans votre avis ils vous mettent un essai gratuit de 1 mois et vous préleve derrière.

Je ne leur souhaite que le pire. Des crapules.
Je vous abonnez surtout pas. Service médiocre, équipe mediocre

would strongly advise against relying on this email service for important communication. My account was disabled without a clear explanation, which resulted in losing access to important emails and contacts.

For users who depend on email for work or business, this kind of unexpected restriction can be very disruptive. In my experience, the process for resolving such issues was not transparent or reliable.

Because of this, I personally would not consider it a dependable solution for critical communication needs.

I've been using Proton for a few years now, and it's been nice and stable. I'm primarily using Mail Plus for the custom domains it offers.

2 weeks ago I paid once again for my $4.99 subscription on Google Play. And? I didn't receive any subscription in app. My account then proceeded to get converted to a free account.

So I paid, but Proton's backend didn't pick up my purchase.

I contacted support but they took 2 days to reply

As a consequence:

I've lost a client that I was communicating with from my business email.

After support refunded me, I paid for Mail Plus on the web version from my laptop. Little did I know that I would need to re-setup ALL of the DNS records for my custom domain.

So even after I managed to pay, my emails with custom domain were returning 500s to email senders

This caused me to get debounced by my payment gateway provider and now I'm trying to convince them to unblock my email because there was an error. Which is now slowing down my business because I dont know if they will unblock my email or not and I cannot proceed without a payment gateway.

I did re-setup my DNS from scratch but it's safe to say this is my last month as a paid user. Going to be switching to EVIL google because they, at least, can properly handle payments.

I am a legacy Proton Business customer with a paid two-year subscription and a grandfathered lifetime discount. When Proton launched Workspace Standard, Business Suite customers were migrated automatically at no cost. Legacy Business customers like me were not — despite having functionally identical product access. The only difference between the two plans was price. The customers who paid less got treated worse.
I made eight formal, documented escalation requests over several weeks asking to be routed to someone with authority to address a business-level policy question. Every request was absorbed by the support tier and never executed. I explicitly requested escalation to the Proton Foundation and executive leadership no fewer than eight times. Every request was acknowledged and ignored.
I located Proton's enterprise email address and sent a detailed inquiry describing my professional background and a potential 50-seat Workspace deployment worth between $7,794 and $11,994 per year. I gave their enterprise team six full business days to respond.
They said nothing.
The financial difference that triggered this entire situation was approximately $6 per year — $11 over the remaining 22 months of my paid subscription. Proton chose to ignore a potential $11,994 annual contract rather than bridge an $11 gap for a loyal legacy customer.
Proton's own marketing states they "put people ahead of profits" and have "never raised prices on existing customers." Their treatment of legacy Business customers during the Workspace migration contradicts both claims.
The support agents — Jeff, Joanne, and team lead Marija — acted in good faith within their authority. The failure is structural. Proton has no functional path from a legacy customer to anyone with commercial authority. If you are considering Proton for business use, go in with your eyes open.

Update — May 14, 2026
Proton responded to this review with: "As we have escalated your request to the Enterprise team as per your request..."
For context: enterprise@protonmail[dot]com went silent for six full business days. What produced a response was not my request — it was a Reddit thread with 4,700 views. The escalation wasn't granted. It was forced.
That response came through the same Zendesk support tier, referencing a CC to Proton's Head of Inbound Sales — a position that is currently vacant. Proton is actively recruiting to fill it.
No one with commercial authority has made contact. The rating stands.

I signed up for an email address. I last logged in about a week ago. I tried to log in today and I got an error message that my account was locked for suspicious activity. Seeing that I haven’t sent an email from it yet, and I’m not doing anything on their list of things that could cause it, I’m really annoyed. I was going to use it as my new go-to email but not now. I put in a “help” ticket to “explain why I think the account was locked in error” and it’s beyond useless. If their AI bots locked my account for no reason I can’t see them unlocking it. Seriously go elsewhere for email. I’m glad I didn’t lose anything important.

Für sicherheitsbewusste Nutzer super, sehr zu empfehlen!!

I went to login to my email account as per usual to check my mail but was prevented from doing so on this occasion. My email accounts were ALL being hijacked by google despite Proton's media reputation for being THE number one PRIVACY provider. In order to access my emails my only option was to sign in to my google account via google mail!!! by downloading Proton's App! What's the flippin point of so called enhanced encryption if it's totally reliant on google's mandatory gmail sign in anti privacy monitoring apparatus that's incongruous with privacy?!!! My Proton email accounts should have NOTHING to do with google as a conduit! I was unable to access my emails for several days until I could figure out a way to bypass the compromise which I did NOT appreciate!!! Proton is out of order for doing this!!! What the hell! This is so disconcerting.

Proton has no online customer service and no phone customer service. If you run into an issue, you have to send them an email. In 3-4 days they will respond with an email. If that doesn't solve your problem, start all over again.
They have worst customer service and user experience. Avoid.

Als je privacy je lief is dan ben je bij Proton echt beter af dan bij de gratis andere mailalternatieven. Het werkt ook heel goed, ik heb wel een betaald account genomen na een paar jaar, omdat mijn vertrouwen in hun gegroeid is. Geen spijt van..omdat je in deze tijd niet genoeg aandacht kunt besteden aan het veilig online zijn.

Nichts ist sicher bei Proton.gelöschte E mails waren doch noch abrufbar. Hatte VPN und Email was teuer war. Support nur auf englisch?Hallo, Schweizer Firma! Alles in allem: Mehr Schein als Sein.
Finger weg.

Update, May 7, 2026

No, I will not share my ticket number publicly. You can find it in your system by the number of my email accounts you blocked: three.

I contacted your support, but I got no answers. You haven’t explained why, after receiving a complaint against one of my email accounts, you also blocked all the others. There was NO VIOLATION of your policy. You simply blocked my email accounts without any reason or proof.

I have screenshots, and I have the ticket number if I need to escalate this. But yes, you blocked my three email accounts without reason. That’s why I will suggest everywhere that people NOT use your services, ever.

Be extremely careful before trusting Proton Mail with anything important.

I know it may not be 100% accurate to call Proton Mail a scam, but after what happened to me, it feels painfully close.

One day, they simply blocked several of my accounts. No clear explanation. No warning. Nothing. Just gone.

I lost all my correspondence across multiple Proton accounts in a single day.

When I contacted them, they mentioned some complaint against one of my email addresses. But that raises even more questions. Can someone just complain about a Proton email and have it blocked? And even if that were true, why were my other accounts blocked too?

I asked, but I received no real answer.

So here is my warning: Proton Mail may be fine as a throwaway email service, but I would never trust it with anything serious: personal history, business, or anything else you cannot afford to lose. If you don’t want to lose your emails — don’t use Proton Mail. Never. Ever.

If you still want to use it — don’t. They will block you randomly at some point.

Because I lost years of messages in one day.

No explanation. No accountability.

Just gone.

Yeah, and I have a strong suspicion that they have access to your email content.

Locked out of the account without any valid explanation ; unable to recover the account for several days ; poor customer support ; never using it again ; ticket number 4717059

For some reason I can’t receive or send emails to my new employer. I’ve tried multiple times to contact support. They just send you a ticket number and say they’ll get back to you but don’t.
So I tried hard to fix the problem myself but hit dead ends because you need Protons admin to change settings.
Basically if you run into trouble you’re on your own, there is no customer support.
I’ve consequently cancelled my mail plus subscription. It’s a shame because I do like the platform.

Don't believe all this stuff about being based in Switzerland lessens the chance of you being taken advantage of. I am a senior but apparently I subscribed to Mail Plus ($59.88 CAD) something I would never do when my pension don't even pay the rent. Another word of advice don't put documents on these websites just because they offer you space. You wouldn't give your documents to a stranger on the street so why would you do it on one of these sites.

ProtonMail is absolutely fantastic for keeping my inbox safe from any scam. The encryption is top-notch, filtering out fake emails and phishing fraud easily. I switched to this service after an old account got hacked and my data was stolen. I feel completely secure here.

Het valt me op dat veel negatieve reviews hier op Trustpilot de plank volledig misslaan. Veel mensen begrijpen blijkbaar niet hoe online privacy werkt: als een dienst geen reclame toont en je data niet verkoopt, dan kost die beveiliging simpelweg geld.

Ik ben onlangs overgestapt van NordVPN en NordPass naar het maximale premium-pakket van Proton, en het is elke euro dubbel en dwars waard.

Waarom ik overstapte:
Layout & Overzicht: Voor mij is de interface van Proton Pass een verademing. Het is veel groter, duidelijker en overzichtelijker dan de layout van Nord, waar ik altijd moeite mee had. Mijn kluis met ruim 1100 items is nu eindelijk prettig leesbaar en makkelijk te beheren.

Nooit meer spam: In tegenstelling tot Google Mail, waar je mailbox op den duur 'beschadigd' raakt door een eindeloze stroom spam die je niet meer wegkrijgt, heb ik bij Proton de volledige controle.

Instant Aliassen: Het aanmaken van tijdelijke e-mailadressen werkt letterlijk binnen één seconde.
Als ik me ergens eenmalig moet aanmelden of een website niet vertrouw, maak ik direct een alias aan. Komt er daarna ongewenste troep op binnen? Dan verwijder of blokkeer ik dat adres instant en is mijn hoofdmailbox weer schoon.

Eigen Domeinnaam: In combinatie met mijn eigen domeinnaam is dit helemaal geweldig.
Ik kan professionele adressen gebruiken en toch mijn identiteit afschermen waar ik dat wil.

E-mail afschermen in de kluis: zoals ik zelf heb uitgezocht: de integratie in de wachtwoordkluis om je e-mail direct af te schermen is uniek en geeft een enorm veilig gevoel.

Veiligheid kost geld, maar je krijgt er Zwitserse precisie en een spam-vrij leven voor terug.
Een absolute aanrader voor de ervaren gebruiker die privacy en overzicht serieus neemt!
