Couldn’t be happier after leaving Google **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Professional Training & Coaching **Reviewed Date:** June 05, 2026 **What do you like best about Proton Mail For Business?** Proton’s privacy policies and focus is why I chose them for my mail provider. Having PGP encryption enabled is also important. **What do you dislike about Proton Mail For Business?** My only minor complaint (maybe too strong of a word) has to do with notifications using the iOS app. I have multiple domains in my account and several email addresses. Emails are filtered into folders based primarily on the recipient. The app shows the number of unread emails on its icon, but only for unfiltered messages that are not moved into a folder. It would be nice to have the option to show the number of unread messages in all folders. **What problems is Proton Mail For Business solving and how is that benefiting you?** The biggest thing is easy PGP encryption support. Works great. ### 2. Proton user for independent consulting **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Consulting **Reviewed Date:** June 03, 2026 **What do you like best about Proton Mail For Business?** Proton Mail's emphasis on privacy and security, its emerging productivity suite, and its customer support have all been strong points. **What do you dislike about Proton Mail For Business?** I find the search function in Proton Mail to be clunkier than some of the larger/established email platforms (e.g., Gmail, Outlook). Proton also currently lacks a web-based Powerpoint/Google Slides equivalent, which would be an asset for business applications. **What problems is Proton Mail For Business solving and how is that benefiting you?** I came to Proton from a free service where, as they say "your data is the product", and Proton has met my needs and expectations for privacy. Customer support, when I've had problems, has been very responsive and effective. I've also been happy with its productivity suite (i.e., tools like Drive, docs, sheets, VPN). ### 3. Privacy that just works **Rating:** 5.0/5.0 stars **Reviewed by:** Matt H. | Project Lead **Reviewed Date:** May 12, 2026 **What do you like best about Proton Mail For Business?** I was concerned moving away from the Google/Microsoft universe would be painful. It was easy to set-up, works with Thunderbird and Outlook well, and hasn't had any issues in the last ~3 months I've been using. For something as critical as email, for me it's about reliability above all else. Was also super easy to integrate with my existing domain name **What do you dislike about Proton Mail For Business?** I've had no issues that come to mind. It just works. **What problems is Proton Mail For Business solving and how is that benefiting you?** A reliable email solution that I'm confident isn't selling or using my data. ### 4. Serious privacy, seriously! **Rating:** 5.0/5.0 stars **Reviewed by:** Rod W. **Reviewed Date:** May 12, 2026 **What do you like best about Proton Mail For Business?** I rely on Proton Mail for safe, secure, and private communications that aren't read, or leveraged to sell my data to sime third party. I can always rest assured that every message I send through Proton Mail is private! **What do you dislike about Proton Mail For Business?** There are a few features that are found in some of the other email services that Proton does not yet have. But I have given up the bells and whistles in exchange for privacy and security. **What problems is Proton Mail For Business solving and how is that benefiting you?** I'm now much more confident that my communications are private. ### 5. Privacy respecting and secure. Maybe a little slow on feature deployment. **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Information Technology and Services **Reviewed Date:** May 15, 2026 **What do you like best about Proton Mail For Business?** I know it is secure. I know my data isn't, cannot be, and won't be used for training an internal AI. The service is solid and always available when I need it. I take great solace in the fact my data is encrypted in such a way to make it very, very difficult for a third party to get at. **What do you dislike about Proton Mail For Business?** The strength of this product is also its biggest weakness - because message content is encrypted, it is not easily searched. That really is my only gripe now that we've had "snooze" functionality. **What problems is Proton Mail For Business solving and how is that benefiting you?** Security, trust and privacy. The fact that I've never had to use support goes a long way to demonstrating how easy and joyful this service is to use. ### 6. Simple and Secure **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Non-Profit Organization Management | Mid-Market (51-1000 emp.) **Reviewed Date:** June 03, 2026 **What do you like best about Proton Mail For Business?** I bought a Proton business account when I set up a custom domain for my family. With aging parents, I needed a secure solution to play IT admin for my family. Configuring the domain and onboarding users was easy. The migration tools provided made this quick work. Encryption is important to me. Being able to say that there's feature parity - almost, anyway - to the other major email providers negates any concerns. **What do you dislike about Proton Mail For Business?** Calendar integration has improved dramatically, but it's quite there yet. I would really like the ability to manage my identity through Proton as you can for Gmail and others. **What problems is Proton Mail For Business solving and how is that benefiting you?** 1. Centralized user IDAM 2. Security 3. Bulk storage ### 7. Satisfaction from migration to use **Rating:** 5.0/5.0 stars **Reviewed by:** Liz B. | Executive Coach, Educational Leadership Consultant, Business Marketing Consultant **Reviewed Date:** June 05, 2026 **What do you like best about Proton Mail For Business?** The excellent ease of migration to Proton from Gmail with 16 years of business emails. Folder and tagging are excellent, logical and colour coding in both very helpful. The user interface is smooth, easy on the eye. **What do you dislike about Proton Mail For Business?** I'd like colour coding on the 'stars' to denote importance level. 3 colours would suffice **What problems is Proton Mail For Business solving and how is that benefiting you?** Value for money, a whole suite of services that I can choose from and pay for only what I use. ### 8. Safe Hands, Excellent Product **Rating:** 5.0/5.0 stars **Reviewed by:** Kieran B. **Reviewed Date:** April 23, 2026 **What do you like best about Proton Mail For Business?** I always feel like I'm dealing with people at the top of their game who understand their business completely. **What do you dislike about Proton Mail For Business?** I cannot think of anything negative to be honest **What problems is Proton Mail For Business solving and how is that benefiting you?** Everything runs seamlessly and simply means I don't have to think about being let down by this service. I know if any issues come up, I will be supported by experts. This is particularly valuable as we are a (very) small team with no dedicated I.T. so we need to know that we are supported to the highest standards out there. And we are. ### 9.

I like that the data in emails and calendars and drives cannot be mined and resold. **What do you dislike about Proton Mail For Business?** The only thing I have run into that is an issue is that using the VPN, a lot of companies won't let you into their site. You have to not use a VPN to get where you need to go. That to me is a big downside to the VPN. **What problems is Proton Mail For Business solving and how is that benefiting you?** Security for my customer's information and for my proprietary business information. ### 11. Peace of mind **Rating:** 5.0/5.0 stars **Reviewed by:** Bert v. | Senior Vice President Hotel Operations **Reviewed Date:** June 05, 2026 **What do you like best about Proton Mail For Business?** I moved from Google to Proton. The motivation was the end to end data encryption and data not stored in the USA. It is easy to setup and to use and costs are reasonable. I like the new business tools and will probably switch 100 % from MS 365 by the end of this year. **What do you dislike about Proton Mail For Business?** I have not found any downsides using Proton Mail for Business. **What problems is Proton Mail For Business solving and how is that benefiting you?** No usage data collection. ### 12. The most secure email for businesses **Rating:** 5.0/5.0 stars **Reviewed by:** Timothy M. **Reviewed Date:** May 12, 2026 **What do you like best about Proton Mail For Business?** The ability to host all 15 of our companies emails Under 1 account for a price that’s unbeatable. Privacy and security are a key factor for us. We left Google business to set up at Proton Mail. I do wish we had the ability to attach notes to emails. **What do you dislike about Proton Mail For Business?** With some social media accounts, our emails don’t come thru instantly. Like instagram and facebook **What problems is Proton Mail For Business solving and how is that benefiting you?** We chose Proton Mail for its privacy.

I joined to help prevent any future problems from arising regarding keeping data safe which in a way is solving a problem. ### 14.

It's like a safe home for my digital life that I don't have to worry about maintaining myself. **What do you dislike about Proton Mail For Business?** It isn't as seemless as Google suite, so there are somethings I feel I am forced to use Google suite for, like reliable sheet. Proton implement Sheets, but it feels like typing in a plain text notepad rather than an empowered text editor. I have a hard time recommending Proton for my friends and family because they're so used to the ease of Google mail/drive/docs/sheets/slides/etc... Proton just isn't there yet. **What problems is Proton Mail For Business solving and how is that benefiting you?** Gives me peace of mind about my data. ### 18.

Even better, the file transfer process Proton provides through ProtonDrive is not only 10x more reliable than Dropbox, it’s also faster. I’ve never had an upload fail on either mobile or desktop. **What do you dislike about Proton Mail For Business?** Right now it's just limited capabilities with ProtonDrive - sheets is still green, and I would like a standard word processing system. I love where it's heading and hope those features are improved. **What problems is Proton Mail For Business solving and how is that benefiting you?** I don't need to pay an insane amount of money to go through my web hosting service that has limitations on mail space. Proton gives me flexibility in the amount of space I'm given. ### 19.

It also provides all the features that are needed for modern email communications for our business. **What do you dislike about Proton Mail For Business?** Unfortunately there are no “shared inbox” features without the emails going to separate inboxes.

It has been an issue for businesses I have associated with and communicated it as an option for. **What problems is Proton Mail For Business solving and how is that benefiting you?** It solves the security and privacy side of email usage. It ensures that we don’t have to use a Big Tech provider nor do we have to host our own server handling our own mail encryption, which takes time and consistent monitoring. ### 21.

All you have to do is email them to get a signed business associated agreement. The pricing is accessible for a small business as long as you don’t buy things you don’t need. **What do you dislike about Proton Mail For Business?** The spam filters could be improved. I get a fair amount of spam in my inbox and I do have to check the spam folder every week or two to make sure I don’t miss anything important. **What problems is Proton Mail For Business solving and how is that benefiting you?** Working in mental health care, we need to be able to privately email our clients and discuss private health information amongst providers. Protonmail is very financially accessible and user-friendly. ### 22.

Easy to Use, Seamless Suite Integration, and Strong ROI **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Consulting | Small-Business (50 or fewer emp.) **Reviewed Date:** May 13, 2026 **What do you like best about Proton Mail For Business?** I really like how easy it is to use and that it is quite similar to other webmail products.

Whenever possible, we use methods other than email to communicate protected health information. Every once in a while something will end up in an email and we feel reassured knowing that Proton is doing everything they can to keep the message and attachments secure and private for these situations. ### 25. It's Great to Know My Data Is Protected **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Mental Health Care | Small-Business (50 or fewer emp.) **Reviewed Date:** June 08, 2026 **What do you like best about Proton Mail For Business?** I appreciate that my emails are encrypted to everyone I email and that I can create passwords for any emails needed. The schedule send option is also great. **What do you dislike about Proton Mail For Business?** The way that the emails are organized is not the most intuitive.

My team has the same problem. **What problems is Proton Mail For Business solving and how is that benefiting you?** I have to have a secure way to email clients, and Proton Mail allows that for me and my team. ### 26.

Improves work productivity tremendously **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Consulting **Reviewed Date:** June 05, 2026 **What do you like best about Proton Mail For Business?** The webpage and app make are nearly identical so using the application is smooth. The website/app allows you to organize emails in folders and modify they look of the platform to your liking. **What do you dislike about Proton Mail For Business?** I would like Proton Mail to offer a section similar to Google to unsubscribe from emails, and allow more than 100 items to be deleted at once. This would be helpful for cleaning up email box for a business that receives a ton of emails that are spam. **What problems is Proton Mail For Business solving and how is that benefiting you?** Proton mail offers a professional presentation for our team and matches the aesthetic of the company. ### 30. I don't want to be the product anymore **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Consulting **Reviewed Date:** June 05, 2026 **What do you like best about Proton Mail For Business?** The priority on privacy, security and end-to-end encryption is what drew me to Proton Mail, initially migrating away from Google's services. The ease of adding custom domains and additional email accounts was a big driver for me. **What do you dislike about Proton Mail For Business?** I haven't discovered a downside for Proton Mail. I have found a few quirks with my booking calendar not displaying on the mobile Proton Calendar app, but that's about it. **What problems is Proton Mail For Business solving and how is that benefiting you?** Helping me manage my various email addresses and accounts in a more private and secure way. I don't want to be the product using a service such as Google anymore. ### 31. Privacy-First Model **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Management Consulting | Small-Business (50 or fewer emp.) **Reviewed Date:** May 12, 2026 **What do you like best about Proton Mail For Business?** What I appreciate most is that Proton doesn't treat privacy as a mere marketing buzzword. The strict zero-data retention (ZDR) model and end-to-end encryption mean that the provider literally cannot access our internal communications, scan our metadata, or hand anything over to third parties. From an administrative standpoint, the centralized console lets you manage aliases, toggle VPN access, and adjust storage quotas without ever breaking the zero-access encryption of individual mailboxes. **What do you dislike about Proton Mail For Business?** Compared to the massive cloud storage you get out of the box with Microsoft or Google, Proton's entry-level business tiers are relatively restrictive. **What problems is Proton Mail For Business solving and how is that benefiting you?** Unlike other services, Proton's ZDR model aligns perfectly with our strict privacy-first operational philosophy. ### 32. Private & Trustworthy **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Computer & Network Security **Reviewed Date:** June 09, 2026 **What do you like best about Proton Mail For Business?** I like that Proton is privacy and security first, while still offering nearly all the features I need for my business. Spam filtering works better than I expect, users are easy to manage, email trackers are blocked, and the setup workflow was quite simple. **What do you dislike about Proton Mail For Business?** Since emails are encrypted at ingress, mail flow rules become problematic without using an always-on host with Proton Bridge. That is a very important consideration for businesses where mail flow control is essential. **What problems is Proton Mail For Business solving and how is that benefiting you?** Proton provides mailboxes for my staff that prioritize privacy and security. So far, no complaints on usability. ### 33. Proton's software is peace of mind that I recommend to everyone **Rating:** 5.0/5.0 stars **Reviewed by:** Matt D. | Owner, Small-Business (50 or fewer emp.) **Reviewed Date:** May 14, 2026 **What do you like best about Proton Mail For Business?** Proton’s encryption features are straightforward and easy to use.
