I love the security and customization options they provide as a part of the service. I pay per user, but have a high number of custom domains, email addresses, calendars, VPN connections and access to Proton Pass all for the one reasonable price. I also appreciate that they are consistently improving their product and adding new features. Review collected by and hosted on G2.com.

There haven't been any major issues. I've been happy to pay the subscription year on year. Review collected by and hosted on G2.com.

Proton Mail is a solid service.

Yes, privacy and security are paramount.

But the key with Proton Mail is it is well organised.

Not bloated.

For me, in migrating to Proton years back, these were key reasons for doing it.

Sure, most people cite privacy.

But no firm can run just on that.

They have to offer productivity and ease-of-use.

Proton does.

Unlike big tech offerings, Proton does inject features left right and centre —

most of which you don't need or simply get in the way of use.

The phone app is fast, and again, just works.

No bloat.

Privacy matters.

Proton has long been known for that.

But the key is Proton Mail is just superior tech. Review collected by and hosted on G2.com.

Simply that the phone app needs to incorporate live links.

Past in a link and it's active.

This is one area where I'd say:

"Come on, get it sorted now!" Review collected by and hosted on G2.com.

Generally I like the mentality that Proton has around data. I'm happy to pay money because their service costs money to run. Previously I paid google cloud money and while I know it also costs google money to operate they are making money both on me as a customer and from advertisers. As a result their intensives are split between me and the corparations that are paying them for my data. Proton as far as I know primarily makes money from it's users so it's incentivized to serve users first and foremost. It shows in the years I've been a paying customer they are consistently emailing me about new features and I'm always like cool I was happy with just email but yet they continue to add more features. The latest one is meetings I haven't used it yet but next time I need to do a video call I plan to try it out. If it works well then I'll never need to use zoom or google meet again.

Niche problem but their contacts tab could use a little work. I use it as a backup for my phone contacts and as a result my phone contacts have been filled with every single email address I've ever emailed even the one time Craigslist ones. I wish there was an option to export only contacts with phone numbers. Also mobile email search (content, not just subject line) would be nice but since I switched to a dumb phone this hasn't been a problem an annoyance. Review collected by and hosted on G2.com.

I have been using Proton as a small business owner now for over two years. I believe it is the best option out there for things such as email and password management. I have my domain setup for email and use their VPN services. Everything works with such ease and my data feels more safer than handing it over to some of the other tech giants. They have continued to improve year over year (often taking suggestions from users) and their "workspace" has allowed for such easy integration of services. Additionally you get all their services for one simple price. Review collected by and hosted on G2.com.

If I had to choose something, I would state their email app could use a IO improvement, but its not bad - I'm partially being picky here. Review collected by and hosted on G2.com.

Good pricing and a company that actually respects its users. Features are being added and improved and it has come a long way from the early days. It’s easy and straight forward to manage domains, aliases, addresses, users, and everything else that is unnecessarily complicated on other mainstream solutions. Proton has covered all basic business needs with its full suite of tools, so it doesn’t feel like you’re missing anything huge. Review collected by and hosted on G2.com.

Drive stands to be improved the most with lack of fine API access and a better way to sort files. Docs would be nicer if it supported more formats, custom export, etc. Review collected by and hosted on G2.com.

I value their commitment to privacy. I recently made a personal account after my business started using it. And it’s been a good switch. I value my privacy and I value the systems it puts in place to prevent trackers. Review collected by and hosted on G2.com.

Not much to exactly dislike, I suppose only that it doesn’t have the same connection to larger office systems like the alternatives do. But not much to hate on an email service. Review collected by and hosted on G2.com.

Proton Mail makes it easy to setup custom domains (one or many) - safely! They handle the complexities in getting things like SPF and DKIM configured properly in a straightforward step by step process. I also really appreciate the administration dashboard: it's well laid out, easy to understand and easy to manage individual users and - importantly - has stayed consistent over time, without the frequent, arbitrary changes often seen from other tech companies.

Setting up things like forwarding addresses or shared inboxes has been difficult/impossible. I recognize that this is difficult to do while maintaining the high degree of privacy & security that Proton builds its brand around but businesses often need an address that multiple users can access (eg, a "support@company.com" address) and simply creating an account with shared login credentials is less than ideal for a number of reasons (no access control, poor security, adds unnecessary cost to name just a few). Proton does recognize this and has been taking steps to get this feature available, but I don't feel like it's there yet & after implementing some of their earlier methods of handling forwarding addresses I now find myself stuck with a forwarding address tied to a specific user account & unable to migrate without losing data.

I am a self-employed freelancer and need an email system to manage business emails coming to and being sent from my domain. Because it is free, I used to use Gmail for this purpose but I did not enjoy using a Google product (because of their business practices) and I struggled to reconcile their policies with the data protection requirements I needed for my self and my clients. Switching to Proton was very straightforward and Proton Mail has almost all of the functionality I had got used to with Gmail. The monthly price is affordable and I am able to meet (and demonstrate) my data protection requirements much more easily, which makes the price worth paying. Review collected by and hosted on G2.com.

Some of the functionality that you get used to when working with a well-established setup, such as Gmail, isn't available within Proton Mail. The vast majority of functionality I need is there, but a few things (mostly around folder structure and cataloguing/categorising of emails) isn't yet available.

Proton Mail for Business gives me a much stronger sense of privacy and control than most typical business email platforms. The encryption, clean interface, custom domain support, and overall reliability make it easy to use day to day, without feeling like I’m sacrificing usability for security. It’s been a solid fit for professional communication, especially in situations where privacy and data ownership really matter. Review collected by and hosted on G2.com.

The biggest downside for me is that some integrations and advanced workflow features don’t feel as seamless as they do in larger business email ecosystems like Microsoft 365 or Google Workspace. There can also be a bit of friction when collaborating with people or using tools that assume everyone is on Gmail or Outlook. Still, I find the privacy and security benefits well worth that tradeoff. Review collected by and hosted on G2.com.

I migrated to Proton Mail for Business from Google Workspace and from an attempt to host my own mail server in the cloud. Proton Mail for Business gives me the control I need for a reasonable price and with a reputation for security. Since I've migrated to the platform, I have had far less spam and overall email issues. I highly recommend this product to anyone that is looking for a secure, simple, and safe email provider. To add, the combination of servicea available in the Business level subscription definitely makes the price worth it. Review collected by and hosted on G2.com.

The only negative take that I gave for Proton Mail for Business is the application. There are functions within the application itself that are easier with Google than Proton Mail. For example, archiving email is a two or three step process in the Proton Mail Android app whereas in Google that is a normal main page function. Review collected by and hosted on G2.com.
