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. ### 2. 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.

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. ### 4.

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.

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.

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. ### 14.

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. ### 15.

Adding new users, specifying the amount of storage each user can get- all that is easy to do. Layered on top is great privacy protection and support.

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. While this has not been an issue for my business. 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. ### 17. Great overall **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Mental Health Care **Reviewed Date:** May 12, 2026 **What do you like best about Proton Mail For Business?** I love that the service is automatically HIPAA compliant and they don’t charge extra for that. 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. ### 18.

Easy to use **Rating:** 3.5/5.0 stars **Reviewed by:** Verified User in Online Media **Reviewed Date:** July 28, 2026 **What do you like best about Proton Mail For Business?** I like how the email is encrypted. I don't use the email for anything else really besides its encryption feature. **What do you dislike about Proton Mail For Business?** I don't necessarily like having to have a separate app on my computer to get email delivered to my computer's mail app, but the app is necessary for encryption and it's fine since it runs in the background and doesn't require attention. I still need to set up email delivery on my phone. **What problems is Proton Mail For Business solving and how is that benefiting you?** Secure email. ### 23. 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.

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.

They allow me to subscribe to different services while giving me full, one-click control to unsubscribe (disable alias) That single click not only unsubscribes me from that service, but also prevents any additional emails when my address is distributed (which inevitably happens).

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. ### 32. 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. ### 33. 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. ### 34. 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.
