Getting started with SMTP API

SMTP API allows you to send HIPAA compliant transactional email messages from apps or software that support SMTP. This is a no-code option for organizations that don't have dev resources.

Setting up SMTP API

  1. Generate an API key in the Paubox Dashboard
  2. Configure your app's SMTP settings using the following credentials:
    1. SMTP server host: smtp.paubox.com
    2. Port number: 25, 465, or 587 supported (unencrypted connections not accepted)
    3. Username: apikey
    4. Password: <your API key>

For more detailed instructions, reference the dev docs.

 

FAQ

What's the difference between Paubox SMTP API and Paubox Email API (REST API)?

  • Paubox SMTP API is easier to setup, as it works with any SMTP-compatible server or application. There's no development or coding needed.
  • Paubox Email API (REST API) affords more customizable control and is best suited for software developers building custom applications or workflows. 

How does Paubox SMTP API work?

  • Automatic encryption. Paubox SMTP API automatically encrypts all email sent through it. 
  • Patented fallback solution. If the recipient isn't capable of accepting encrypted email, a secure link is generated to view the message via the Paubox Secure Message Center.

Are HIPAA compliant attachments supported?

  • Yes

Are dynamic templates supported?

  • No. To take advantage of dynamic templates, use Paubox Email REST API instead.

If I'm using Paubox's SMTP Server Solution (legacy) product, can I migrate to SMTP API?
