Yes. When a customer uses Paubox, they do NOT have to change their business email address.
The key to the answer is customers must have a business email address. Some small businesses, like a solo practitioner, often do not have a business email address and use a consumer email platform. The difference is in the domain name.
An even bigger difference is there is no Business Associate Agreement given with a consumer email address, which is critical for HIPAA compliance.
Paubox will seamlessly integrate with your business email platform, like Google Workspace and Microsoft 365, allowing you to keep your business email address the same!
