Given the nature of our work, we already handle sensitive personal data, so it’s essential to think carefully in advance about security and the safety of our staff.

We’re also looking forward to further developments. **What do you dislike about Proton Mail For Business?** As a 100% volunteer-run organisation, we do find it a shame that the cost per user is sometimes higher than, for example, the basic Microsoft 365 plan, which sometimes prevents us from giving a volunteer their own account.

Of note, they can access a free tier, so both ends of the comms chain can benefit fro hyper-secure, reliable email communications without having to be a cyber security expert. It's very simple to set up on both sides, so non-native language speakers and technical experts can get set up just as easily. It has never failed to work for me, we've never lost an email and we feel exceptionally protected. **What do you dislike about Proton Mail For Business?** There are only two problems with the desktop app. If you archive an email in the junk folder it marks the sender as safe instead of just hiding the email. The buttons are side-by-side so its a common error. The second is that the undo buttons stack up when deleting multiple emails, and they can get in the way of the button to archive or delete more. Small friction on a great product. **What problems is Proton Mail For Business solving and how is that benefiting you?** I want a reliable, trustworthy email platform for my organisation that can meet the needs of our clients without introducing financial or technical burdens. ### 25.

Love the privacy! **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Mental Health Care **Reviewed Date:** May 12, 2026 **What do you like best about Proton Mail For Business?** Using Proton Mail has been seamless. I like the privacy aspect and knowing that they don't read the emails in order to send ads based on what's coming in and out. Working in mental health care this is incredibly important as I have clients that email me and I want to remain HIPPA compliant. **What do you dislike about Proton Mail For Business?** I don't know if I have any. It's worked well for me. If I was forced to give an answer, the app can sometimes feel clunky, but I mostly use it from my web browser. **What problems is Proton Mail For Business solving and how is that benefiting you?** I mentioned it in what I like about it, but it's solving the privacy issues I have with Google. I can get more services that I would use from Google, but I like the peace of mind regarding privacy that I have with Proton. ### 27.

After about two years of using it, I felt Proton Mail had reached a level I was comfortable relying on for business email as well. At that point, I migrated my business email from Microsoft 365 Exchange to Proton Mail. **What do you dislike about Proton Mail For Business?** Syncing and managing contacts feels disjointed and unmanageable from a business perspective. There should be a separate place to manage contacts outside of Proton Mail, rather than having everything tied to the mail interface. Both for individual users and a business level. **What problems is Proton Mail For Business solving and how is that benefiting you?** Secure Business communications ### 29. Excellent Privacy focused email and calendar **Rating:** 5.0/5.0 stars **Reviewed by:** Neil S. **Reviewed Date:** June 05, 2026 **What do you like best about Proton Mail For Business?** User friendly interface.

Robust Security with Great Multi-Address Flexibility, but Comes at a Premium **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Computer Software **Reviewed Date:** June 03, 2026 **What do you like best about Proton Mail For Business?** The security features give me real peace of mind when handling business communications. I also really appreciate the strong support for multiple aliases and email addresses—especially the catch-all address functionality—which helps ensure we don’t miss any important client emails. **What do you dislike about Proton Mail For Business?** The pricing feels a bit expensive compared to standard business email providers. On top of that, setting up and configuring the SMTP integration for our third-party apps was frustrating and unnecessarily annoying, and it took more effort than it should have. **What problems is Proton Mail For Business solving and how is that benefiting you?** Standard email leaves sensitive corporate data open to leaks and external scanning.

I wanted truly strong end-to-end encryption that would keep my messages safe from ad-serving nexuses. **What do you dislike about Proton Mail For Business?** I’d like a to-do task list that integrates with my calendar, and I also want the ability to upload and index .nsf files so I can store and access my old Lotus Notes content. It would also be helpful if I could add emails to my calendar or to-do notes with a single click. **What problems is Proton Mail For Business solving and how is that benefiting you?** It provides the same core functionality as Gmail, Yahoo, and Outlook, but with added privacy protections. That gives me confidence that ProtonMail’s infrastructure stays neutral toward my content and offers a hosted space without any attitude or judgment.

Outstanding Product, Useful Features **Rating:** 5.0/5.0 stars **Reviewed by:** Karen F. | Creative & Marketing Strategist, Small-Business (50 or fewer emp.) **Reviewed Date:** May 15, 2026 **What do you like best about Proton Mail For Business?** First and foremost, I appreciate the security features and the ability to create aliases to reduce spam. I am a daily user and like the simple and uncluttered interface. **What do you dislike about Proton Mail For Business?** My only real complaint is the inability to thread and organize emails. There are limited options for color coding and optional views. This is strictly an interface and not performance-related. **What problems is Proton Mail For Business solving and how is that benefiting you?** Proton Mail is a one-stop solution for managing multiple accounts.

I've found it to be reliable and secure. Having the peace of mind of knowing that my email communication is end-to-end encryped has been great! The recent additions of the Proton Drive, updates to the Calendar have made it much more functional. I appreciate the new Docs and Sheets as well as the secure storage on the Drive. Overall, the security of the email has been super, and the new Drive features have greatly improved the user experience. **What do you dislike about Proton Mail For Business?** Sheets is still a bit cluncky, and the "Share" feature on Docs as well as Sheets is still a bit cumbersome.

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. ### 46.

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). ### 48.

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. ### 49.

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. ### 50. 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. ## Proton Mail For Business Discussions - [When is the launching date of proton drive?](https://www.g2.com/discussions/when-is-the-launching-date-of-proton-drive) - 1 comment, 2 upvotes - [What is Protonmail used for?](https://www.g2.com/discussions/protonmail-what-is-protonmail-used-for) - 1 comment - [Can police track ProtonMail?](https://www.g2.com/discussions/can-police-track-protonmail) - 1 comment - [Is ProtonMail legitimate?](https://www.g2.com/discussions/is-protonmail-legitimate) - 2 comments - [View Proton Mail For Business pricing details and edition comparison](https://www.g2.com/products/proton-mail-for-business/reviews?page=3§ion=pricing&secure%5Bexpires_at%5D=2026-08-03+12%3A24%3A42+-0500&secure%5Bsession_id%5D=4ee84674-3ba6-4d2e-bb56-2a67b8056948&secure%5Btoken%5D=ba6595cc24439df6d3abb3a2f26713e977aba0f7197f013d707d749243c6a0f2&format=llm_user) ## Proton Mail For Business Integrations - [Apple Mail](https://www.g2.com/products/apple-mail/reviews) - [Custom Web Application Development](https://www.g2.com/products/mind-it-systems-custom-web-application-development/reviews) - [Microsoft Outlook](https://www.g2.com/products/microsoft-outlook/reviews) - [Thunderbird](https://www.g2.com/products/thunderbird/reviews) - [Zoho Desk](https://www.g2.com/products/zoho-desk/reviews) - [Zoom Rooms](https://www.g2.com/products/zoom-rooms/reviews) ## Proton Mail For Business Features **Generative AI** - AI Text Generation - AI Text Summarization **Encryption Techniques - Email Encryption** - Encryption Algorithms - Transport Encryption - End-to-End Encryption **Authentication, Verification, and Access Controls - Email Encryption** - Revocation Mechanisms - Access Controls - Digital Signatures - Certificate Authorities **Security Enhancements and Auditing - Email Encryption** - Malware Scanning - Reporting **Integration, Compatibility, and Usability - Email Encryption** - User-Friendly Interfaces - Email Client Integration - Automation ## Top Proton Mail For Business Alternatives - [Spike](https://www.g2.com/products/spike/reviews) - 4.6/5.0 (250 reviews) - [Google Workspace](https://www.g2.com/products/google-workspace/reviews) - 4.6/5.0 (45,644 reviews) - [Microsoft Outlook](https://www.g2.com/products/microsoft-outlook/reviews) - 4.5/5.0 (3,430 reviews)
