I'm a solopreneur with two businesses, and Proton Mail seamlessly integrates my personal and work emails (from different domains) into one place so I never miss anything important. And I never have to worry about the safety of my communications because of Proton's encryption. Plus, every year my email storage space grows with my businesses.

I haven't really experienced any downsides yet. Upgrading to enable two domains was simple and easy, and domain verification was also straightforward without any issues. Review collected by and hosted on G2.com.

To me, the use of Proton Mail is all about privacy and security. I've used it for 5 years now, and have experienced very few technical issues. It doesn't take much research to learn that Proton (as a company) is top notch... they don't put out ANY product or service without building a high level of security into it. They don't add a lot of unnecessary fluff. So, it meets all my requirements - fast, reliable, secure, and private. Also, the pricing model is fair and does not have weird unexpected fees added.

I really have no complaints. I could imagine that there are those who want Proton to put out new or additional features more quickly, but I'm not one of them. I like their thoughtful cadence, and appreciate that they don't put out junk before it is ready. Review collected by and hosted on G2.com.

Proton is, at its core, security and privacy focused with tools to ensure this remains the focus. Yet, more products continue to release turning the core of what they do into a true business suite of applications which is also a great alternative when most companies you would traditionally used are based in the USA. Each product is well polished supporting multiple OS systems and most importantly updates and improvements are not slowing down reacting to the requests of the community around it.

I would like more integration with Linux when/if possible particularly around the Proton Drive product to allow more fluid syncronisation among products. Review collected by and hosted on G2.com.

It's extremely easy to use and I enjoy the automatic encryption when emailing with my coworkers. I've started using the calendar integration much more which is also a nice feature inside of the Proton Mail app. For me it's the added security which makes me feel more protected then sharing every single thing I do with Google or Microsoft. I assume none of my data is being used for advertising or training AI, which is vital as we work on highly confidential communications. Review collected by and hosted on G2.com.

I'd like more integrations like the Google Suite or Office Suite, but I am confident this is on their roadmap! Real-time mail alerts seems to have a bit of a lag, as I get notifications on my phone before I do on desktop (possibly user error not setting it up to poll more frequently).

I appreciate that security is the #1 priority by design, and that Proton has continued to stand behind that commitment even when facing legal challenges aimed at undermining user trust. The app feels stable and well built, with a pleasant UI; something that really shouldn’t be as rare as it is these days compared to other products. Review collected by and hosted on G2.com.

Sometimes I wish the web UI offered more options for searching and sorting emails, but that’s where Protonmail Gateway comes in, since it lets me use my preferred email client instead. Review collected by and hosted on G2.com.

Initially, the main driver of switching to Proton Mail was the privacy and security provided by Proton Mail. However, since that time, Proton has added services (such as VPN, Drive, Calendar etc.) that have been nice additions to the platform. Proton's customer service is also great - responsive, knowledgeable, and you are not passed around to a bunch of different agents to resolve your issues. I highly recommend Proton for any business that is concerned with the security of their communications and wants the added benefits of a suite of productivity apps that can help them with their business.

The biggest downside was initially marrying up our email clients with our Proton accounts. However, the most recent versions of the mail bridge have simplified this process. Review collected by and hosted on G2.com.

It is secure. I have incredible mail filtering, I'm able to manage my calendar from the app. It syncs seamlessly with other calendar systems (aka when I send or accept an invite it doesn't look funky on either end). I can use newsletter views, customize my folders, color code everything, and an archive with real storage levels. I love how many email addresses I can create, even with other domains.

I wish I had something bad to say, I really do. But I don't. I guess maybe I wish their AI email writer was better, but I never use it in the first place. Maybe for others they'd care about that. Review collected by and hosted on G2.com.

Efficiency. Elegance. Simplicity. Effectiveness. Security. Encryption. In particular, I work with writers scattered all across the world. Many of them have incurred the wrath of their governments. Proton Mail enables me to communicate with them in a manner that protects them from surveillance and reprisal. Review collected by and hosted on G2.com.

I have not found any disadvantages. Sorry to disappoint you. I have used Proton's products for ten years and have not found any of them to be flawed. Nor have I been disappointed. I am in fact pleased by their ongoing effort to improve the products they have created already and to create new ones. Review collected by and hosted on G2.com.

I thought the transition from Gsuite would be hard but it's been easeful and smooth. I have a product-based start-up and as a small business owner Proton Mail for Business has felt so aligned. I appreciate the affordable monthly cost that comes with a generous amount of aliases, websites that can be used for email, password software, authenticator software, VPN, and the whole workspace that I haven't fully explored yet as it was just launched recently. I love that each year you renew your account you're rewarded with an increase in storage space. It truly feels like a company that genuinely cares about doing right. I'm truly in love with having been with Proton for over 3 years now for my business. Review collected by and hosted on G2.com.

The only downside I see is that the calendar doesn't integrate as smoothly as Gmail's calendar does with my apple calendar. I haven't been able to sync it properly to setup an appointment calendar that can know blocked off dates between Proton business calendar and my personal calendar -- not sure if this is on me not knowing how to set it up or that the functionality doesn't exist yet.

I love that with Proton Mail I am able to do business remotely and seamlessly switch between web, desktop and mobile access. This program is both secure and functional. We have never had any downtime. Review collected by and hosted on G2.com.

I use the web and mobile versions most. In my opinion, the calendar is not seamlessly integrated and I feel like I never know what is coming up so I tend to use the calendar app on my phone. Review collected by and hosted on G2.com.
