Paubox solves the usability problem that plagues secure email: its encryption works invisibly, delivering HIPAA-compliant messages straight to recipients' regular inboxes with no portal logins, passwords, or extra clicks — which means clients actually read and reply to your emails. It layers on top of Google Workspace or Microsoft 365, adds inbound threat protection, and provides a BAA; higher tiers include marketing email tools for compliant newsletters and an API for transactional messages from applications. For therapy practices, the portal-free experience is more than convenience: anxious or ambivalent clients drop off when a 'secure message' requires account creation, so frictionless delivery has clinical-engagement value. Pricing is per-user and somewhat above Hushmail, without Hushmail's built-in forms. Practices already living in Gmail or Outlook who want compliance without changing anyone's habits are the perfect customer.
