AB Andrew B. Founder 6/4/2026 "Excellent privacy and encryption, but limited third-party integrations" 4/5 What do you like best about Proton Mail For Business? The biggest reason I use Proton Mail for Business is that it is privacy-first by design. I deal with sensitive and critical information, so having end-to-end encryption, strong phishing and scam detection, and a provider that is not scanning or reviewing my emails is extremely important. Review collected by and hosted on G2.com. What do you dislike about Proton Mail For Business? The main drawback is the limited support for OAuth and third-party integrations compared to platforms like Google Workspace or Microsoft 365. Proton Mail is excellent for privacy and secure communication, but if your business depends heavily on connecting email to other tools, CRMs, automations, or external apps, the workflow can feel more restricted. Review collected by and hosted on G2.com. What problems is Proton Mail For Business solving and how is that benefiting you? My business needs privacy to operate.

Founder 7/21/2026 "It’s a full eco system" 5/5 What do you like best about Proton Mail For Business? I like how secure it is without sacrificing features. The only bad thing I had to say about it has been fixed too (it was a little difficult to find some e-mails) but the search function is now amazing. So it’s everything you want from an e-mail provider just safer. Review collected by and hosted on G2.com. What do you dislike about Proton Mail For Business? I don’t think it’s lacking in anyway. And the team still find ways to make improvements constantly Review collected by and hosted on G2.com. What problems is Proton Mail For Business solving and how is that benefiting you?

Proton Mail For Business gives me peace of mind knowing my business communications are protected with strong encryption and a company philosophy that genuinely prioritizes user privacy. The interface is clean and easy to use, onboarding was simple, and features like custom domains, aliases, calendar integration, and Proton Drive make it feel like a complete ecosystem instead of just an email provider. I also appreciate that Proton is independent and not built around advertising or data collection. Review collected by and hosted on G2.com. What do you dislike about Proton Mail For Business? Some third-party integrations and workflow automations are not as seamless as more mainstream providers like Google Workspace or Microsoft 365. Occasionally there are small limitations when working with external calendar or productivity tools. The platform has improved a lot over time, but there are still a few advanced business collaboration features I would like to see expanded further. Review collected by and hosted on G2.com. What problems is Proton Mail For Business solving and how is that benefiting you? Proton Mail helps me separate my business communications from large ad-driven ecosystems while maintaining a professional and reliable email experience. It improves security for sensitive conversations, protects client and company information, and gives me more confidence in how my data is handled. Using Proton also simplifies managing multiple domains and accounts while keeping privacy as a core part of my business operations. Review collected by and hosted on G2.com.

I like that my emails are encrypted and that I don't feel like my information is being sold to the highest bidder. Review collected by and hosted on G2.com. What do you dislike about Proton Mail For Business? There are some nuances from switching to Proton Mail from Google such as email sign ins and verifications to internet apps because Gmail is integrated in everything that having to input my Proton login manually can be a bit tedious. Honestly though it is the least of my worries because it's the privacy part that I value more than the "convenience". I also wish that Proton Mail dark version can render emails campaigns with logos and photos better. For example, when i do a test email from Brevo with my bright blue logo, it simply doesn't show up against the black background but in Gmail, they somehow account for that and add a white background. Again, not a deal breaker. I also wish that I could use aliases where I can send an email using the alias without people knowing my real email. I like it for spam and signing up for deals at stores for discounts and specials. Review collected by and hosted on G2.com. What problems is Proton Mail For Business solving and how is that benefiting you? Proton Mail is great for encryption and I trust that my communication is private. That alone is a huge benefit because I want a sense of security when I am online. Review collected by and hosted on G2.com.

For me personally, safety and security is paramount. Like any other software product, I think there could be work with the UI and making things a little more streamlined, but overall, I think the experience has been excellent. It has all of the features that help make day-to-day e-mail processing efficient and streamlined. Review collected by and hosted on G2.com. What do you dislike about Proton Mail For Business? As I mentioned, the user interface could be a bit more modern and effective. A feature that would allow dictation verbally within the e-mail would be helpful for those that aren't able to type or prefer not to. There aren't very many things that need to be done, it's a pretty good product. Having said this, it would be nice to have the email product and the calendar product and perhaps even the drive product integrated so you could easily access and see all three within one interface. Review collected by and hosted on G2.com. What problems is Proton Mail For Business solving and how is that benefiting you? Safety and security is primary, and I think that proton's whole suite of products do exactly that I have no concerns about access and things like that given proton's security protocols.

As a managed services provider we are regularly working with sensitive information, whether it be PCI, HIPAA, contracts, or credentials. A primary first step in communications with our clients is encryption and data segragation; Proton Mail makes the approach simple and convenient. Review collected by and hosted on G2.com. What do you dislike about Proton Mail For Business? The main hurdle we face in our promotion of Proton Mail over other widely adopted, but insecure, services is the identity management (OAuth2/SSO) integrated in a large number of 3rd party applications. Clients will push back to keep insecure email systems (they don't always separate the service feature from the account) to maintain easy login features to otherwise unrelated applications. (e.g., Utilizing Google account identity for login to a medical EMR web application). While not a Proton Mail issue directly, I dislike the lack of integration. Review collected by and hosted on G2.com. What problems is Proton Mail For Business solving and how is that benefiting you? Proton Mail makes encrypted email simple for our clients; we don't have to walk them through the steps of creating and sharing certificates, integrating the certificates into mail clients, etc. The content of client communication typically contains some amount of sensitive information. The ease of adaptation by clients, saves hours in setting up alternative security measures. Review collected by and hosted on G2.com.

"True to original privacy/security mandate" 4.5/5 What do you like best about Proton Mail For Business? I most appreciate how consistent it is - consistent in terms or reliability, consistent in terms of their constantly-improving security, consistent with constantly improving usability. More specifically, I appreciate how extensive the security features are and that it's the only platform that truly keeps your information private, not only across email, but across all their services. Review collected by and hosted on G2.com. What do you dislike about Proton Mail For Business? What I dislike the most is that I find the feature where you can constantly sync certain files on your PC for backup as a little difficult to use. This may be an issue with any syncing of files, but I almost completely deleted files I needed when attempting to back them up. They need additional safeguards to prevent this. Review collected by and hosted on G2.com. What problems is Proton Mail For Business solving and how is that benefiting you? It's giving me a secure, private and professional platform to conduct my business from. I'm literally being attacked by hackers and overall online miscreates several times a week. I've had proton mail for almost 10 years, and I've never had my email or associated website hacked and I have a TON of emails associated with Proton. It's by far the best for security and privacy for a business because it has docs, password management, cloud storage, notes, and most importantly, the ONLY AI chat which is TRULY private. This plays into my review of Proton Mail, because I often use AI to craft my emails. This for me is HUGE, and in time, I'll ONLY use Proton Lumo AI for my AI purposes. People tend to share the most private things with AI that they wouldn't share with most any other platform, and one can do so on Proton Lumo (Proton's AI) because not even Proton can read your chats. Overall, for a business, the info you're transmitting includes very sensitive personal info and financial info of both your clients and your company and I'm confident Proton is the most secure system for a business. I've been with them from the very beginning, when it was only a email service and they've never sacrificed security for growth. Their original mandate has never changed. They never sacrificed security for growth or monetary gain. Every product has been as secure as the original Proton Mail and integrates perfectly with it. Review collected by and hosted on G2.com.

Overall the privacy, SPAM targeting, and experience using the product are excellent. I feel confident using Proton Mail, especially with colleagues and other Proton Mail users due to encryption and privacy. Internal corporate emails are locked-down. This is essential for any company doing R&D. Review collected by and hosted on G2.com. What do you dislike about Proton Mail For Business? There are several features of the actual mail program that could be improved: headers, better filtering, not having the "make proton mail your default email application" always nagging me (even when I've said "not right now 100x. Cannot use as reader for other (non-proton) email accounts -- so I can't make it my default b/c I still have other email accounts. Doesn't handle integration with other calendars, so I can't use it as default. Doesn't integrate with other contact lists, so it can't be default. etc. Review collected by and hosted on G2.com. What problems is Proton Mail For Business solving and how is that benefiting you? Proton Email solves the issue of confidentiality between other email account holders (especially when they also have Proton Emails). Generally I need private communication mechanisms between teams working on sensitive projects and correspondence: - legal issues - policy proposals - research and development - personal matters - cybersecurity matters Review collected by and hosted on G2.com.

I really like the piece of mind the encryption gives me. Since I deal with sensitive birth data and personal life details for my Vedic Astrology client consultations, knowing that the emails are actually private and secure are a huge plus for my business. It is super easy to manage my professional channel inquiries separately from my personal stuff since I have a YouTube channel with 100K+ Subscribers so I tend to get lots of emails. The interface is also very clean, and the 'Official' sender tags help me stay safe from phishing. Review collected by and hosted on G2.com. What do you dislike about Proton Mail For Business? Sometimes the search feature in the inbox can be a little slow compared to Gmail especially when I am looking for older client threads. Also, it is a bit more expensive than other providers, but honest, the security-trade off and simplicity of the user interface makes it totally worth it for me. Review collected by and hosted on G2.com. What problems is Proton Mail For Business solving and how is that benefiting you? It helps me look more professional. Instead of a generic email, using Proton for my business makes my Astrology Channel feel like a legitimate practice. Plus, I don't have to worry about my data being scanned for ads. The main thing is client trust. When I tell my clients their information is encrypted and secure, it builds a lot of rapport and good will even before we start the consultation.

I've been a long time business user of Proton Mail and I find it to be superior in almost every way to other services out there. When it first launched has a business email product, the administrative controls and overall uptime of the service weren't great. Great. For the past 2 years at least, however, the uptime has been spectacular and the admin panel has been much improved. It has all of the features I need as an administrator to be able to provision, maintain and de-provision user accounts inside my business. Review collected by and hosted on G2.com. What do you dislike about Proton Mail For Business? The biggest criticism I would have for proton mail for business is value for money. It's not cheap and there are competitor, equally as privacy focused alternatives which cost much less per user. It's still the market leader in my opinion for features, uptime and dedication to privacy, but it does feel like they could improve in terms of value and cost per account. Review collected by and hosted on G2.com. What problems is Proton Mail For Business solving and how is that benefiting you? Providing legal services, privacy is a Paramount concern.
