Our verdict

For people who want a hosted email service that uses end-to-end and zero-access encryption as Proton describes it, with a free starting point. Skip it if you need a lot of free storage or send high volumes without a paid plan.

What it does well

  • Free plan with 1 address, up to 1 GB storage and 3 folders/labels
  • Web client and Bridge repos are GPL-3.0 on GitHub
  • Mail Plus gives 15 GB, 10 addresses, 1 custom domain and unlimited daily messages

Where it falls short

  • Free plan caps sending at 150 messages per day
  • No custom domain on the free plan
  • 1-month prices are not displayed on the pricing page

Proton says Proton Mail uses end-to-end encryption and zero-access encryption, and that "zero-access encryption means we never see your inbox, on any plan." Proton also says all its services are open source and independently audited, and describes itself as legally based in Switzerland. These are Proton's statements; we have not verified them independently.

Proton Mail runs on the web, Windows, macOS, Linux, Android and iPhone. Bridge is listed as a desktop client add-on. Proton lists audit reports for Proton Mail web and desktop on its open-source page.
