Proton Mail Reviews 1,664

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.

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.

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.

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.

I requested an export of all of my information from Yahoo Mail to Proton. Proton used their easy switch export tool to do this. About half of the info made it over. The contact names were there, but barely any emails were, not one of my family members as well. The help was horrible. There was no chat and no phone assistance. After some time, I received multiple bot emails from "Monika" of a repetitive nature, even when I reworded my question, hoping she would understand what I was asking. I would receive the same response that didn't apply at all. Google would help at times, but its website is nothing but a headache. While this was going on, I noticed my plan had changed. I purchased their 3.99/month ProtonMail Plus plan at 47.88. At this point, it showed I was switched to their monthly plan at 4.99 a month. I never requested a change. I never received an email. I was okay with this as long as they would give me a refund. That didn't happen. Meanwhile, I continued to solve multiple issues on my own over 5 days. Something popped up called Duo, no pricetag next to it, but advising to try this for my problem. Ok, I'll try this, but I'm highly doubtful. It didn't help. The 4th or 5th day, my plan had been switched to Proton Duo at 19.99. Once again, I never authorized a change, never received an email confirmation. I informed them of this. Monika had zero compassion, only saying they will take it out of the 47.88 I paid and will continue to do so. No options for me. I transferred everything back to Yahoo myself. On Saturday, May 2, I requested that my account be closed and a full refund. The only response was that we need your credit card so we can take more money out of the money so we have a payment option to upgrade your account. I found a page after much digging where you are supposedly able to cancel an account, but there's no cancel option on that page. I only have an overly detailed list of their extremely expensive plans. This has caused me so much unnecessary stress and frustration.

5/4/26: Dear Proton,
I'm always amazed and wonder how people like you and Trump can sit and feel okay with your lies. Are you delusional? Everything you said was a lie. You never sent an email telling me I authorized a change in plans. Because you know I didn't! With the first change you made, had I switched from the yearly plan to the monthly plan why didn't you give me a refund? Why were you holding my money hostage if I had the right to pay monthly and leave? If you were an honest company, you would know that monthly subscribers who paid $44.87 and our company switched them to the monthly plan at 4.99 deserves an immediate refund and sincere apology. This isn't rocket science. I never authorized to upgrade to duo either. You scammed me. I was never informed until I asked your so-called real person, Monika, who is so robotic and must wear an AI costume at her desk. I bet she aced your training class on the importance of lack of compassion and the company is always right. It sure seems like she's been trained that way demonstrated by her mind boggling lack of understanding of my questions and concerns, lack of compassion and lack of taking action regarding this final request. Your company is full of jerks. Your reviews say it all. I've read all of them from every reliable source. Your company is corrupt and a scam. You are predators. Why can't you address what I ask for? I put it out straight to you guys. I took care of making sure everything was deleted or transferred by myself elsewhere. Nothing is on there. You're holding me hostage, will not cancel my account, and take accountability for how you handled this situation. I want my money back. $44.87. I should be asking for so much more for the week of hell you put me through.

5/4 1343: Monika blames me for making the changes. How dare this idiot put the blame on me! I am beyond cautious with my money and never click on things that sound fishy. That's why my credit score is 880. She refused, once again, to refund my money. I hope thousands and thousands do their homework and read these reviews before hastily signing up for this criminal site. They've already been reported to the FTC. I hope they are shaken and taken down for all of the harm they inflict on customers.
5/5: Thank God, now I am dealing with David. He kindly sent an email stating he will fully refund me for my account. Ok. We'll see.
5/7: After multiple requests for a confirmation of refund, I emailed David and told him he was stringing me along a bit too long and avoiding my questions. He responded, he refunded our CC, and it should take 5-10 days. No confirmation of this has been given. I'll let it slide....for now. But watch out, David.

So, having moved over to the Proton family of products, I am impressed. Started off with the free offering, but quickly moved over to an Ultimate subscription.
Based on my opinions opinion of cyber security tools I have used as a professional in 30+ years, this is the most complete set of security solutions I have ever used. And thus fully recommend to any user or organisation who is concerned about Cyber Security Exposure.

I use the tool cross platform between an iPhone 16, MacBook Air and a Desktop iOS platform, and found the family of products from Proton Mail, Calendar, VPN, Authenticator etc to be very easy to use with a low learning curve, and in my case I am now fully migrating over to the Proton Platforms to support my business and personal activities.

On the basis of the above, and other positive feedback, I am at a loss to understand why there are unusually soo ‘many’ negative reviews, and in some cases do question the credibility of the comments.

For Heaven's sake, Proton.
I renewed my subscription in February of 2026.
Now you send me a renewal subscription - monthly - in April.
What the heck are you people smoking?
I am leaving.
Unacceptable.

They terminated my account because I didn't use it for 12 months. I think they did it because of the content of my emails, it's not private, they sell your info. Nothing is free unless you're the product.

2 days and i still cant set my twitch account coz i dont have verified code, what is a point of that mail???

Proton Mail is a convenient app for phone use. Everything was easy to set up, and I had no problems using it. The only downside for me was needing to create another email address for recovery.

Switched to Proton Mail recently because I was getting tired of all the targeted ads on my old email provider. The interface is super clean and minimal, which I love. Knowing everything is end-to-end encrypted gives me a lot of peace of mind. It just works smoothly, and I haven't looked back since.

I've been using their email for about 2 years now. I've been happy with the ease of the service, customizability, and the company's reasonable commitment to privacy. It's nice to have a drive and email that I know isn't being datamined by google.

Absolute and total ignorance dealing with these imbeciles for my mother. I got her one of their free encrypted email address years ago to keep her social security and other personal business private. I should have taken the hint back when I emailed them about how to block unwanted emails and they acted like I was speaking a foreign language (technically I am I suppose since the communication is no doubt with a stupid overseas call center).

She tried Lumo AI and decided she didn't care for it, tried to delete her data/conversations, and they ended up deleting her entire proton acount.
It says "Account scheduled for deletion, please contact customer service". So she did, and they answered two days later and have asked her for everything but a vial of blood and a first born child to get it back. They answer once per day, and have kept her going for almost a week with the stupidest questions ever, some very personal, like banking information.

There is literaly no reason for this. It was a mistake - mainly on their part for their products being unnecesarily complicated. My mother has her name and password, plus the code they gave her initially in case she got locked out. That should be enough.
The "we're sorry but please be patient" schtick has run its course.

The fact that they have a 2 star rating and still try to reply to every unsatisfied customer with the same bulls##t excuses for their poor customer service speaks volumes. We will both use another product regardless of whether they fix the issue or not.

Zero Customer Service .
Shameful lack of consideration for clients and any of their issues or suggestions .
This business shall be gone before they rich success .
Don't bother they all gone fishing to lake ….

I have been using Proton Mail for a while now, and I am highly impressed with its commitment to privacy. The end-to-end encryption ensures that my emails remain private and secure, which is my top priority.
