Build compliant email into your apps and workflows

Send compliant, encrypted email straight from the systems you build and the processes you automate.

Add secure email to your own application or automated workflow over SMTP or our API — with recipient verification and Proof of Delivery built in. There's no encryption for your team to build, and nothing new for your recipients to install.

Automate your workflows

Triggered and scheduled sends, with no one clicking "send":

  • Appointment reminders and patient notices
  • Statements, invoices, and receipts
  • Lab and test results
  • Report and document delivery

Build it into your own app

Drop secure email into the software your team develops:

  • Recipient verification — question & answer, phone code, or password
  • Message expiration and read receipts
  • Custom message policies and branding
  • Link back to a sent message from inside your app

A secure, verified message sent from an application over SMTP — including recipient identity verification.

For your developers

Everything your team needs is in the Developer Guide — SMTP settings (smtp.protectedtrust.com, port 587, STARTTLS), .NET sample code, and the <protectedtrust> options for verification, expiration, receipts, and message policies. See also API & SMTP for creating your access credentials.
