Here are some recent reviews from happy customers:

Aubry D.

The ease of use and the support from the team are outstanding. I’ve never seen anything like it from a business. They understand the barriers to security and have removed them, so you can have secure emails without 17 extra steps. When I hadn’t set it up quite correctly, I received an email and was able to schedule a free meeting with an incredibly helpful member of the Paubox team. It took only a couple of minutes, and it was super easy—honestly, even pleasant. Everything else out there feels too complex and too complicated to be truly effective with clients, but not Paubox. You will not regret it!

"I like that it offers ways to make my email and my intake form HIPAA compliant. The setup instructions were very detailed and easy to follow, which made the process straightforward. Customer service has also been very helpful and responds quickly whenever I have questions."

Justin B.

"Having seamless outbound email encryption that does not require the recipient to login or view emails in a special portal is great when dealing with a multitude of organizations. Customer support was equally great in helping us integrate with both Google Workspace and Microsoft 365."
