Auth0

Configure a custom SMTP email provider in Auth0 so your tenant's emails deliver from your verified domain through Unitpost.

What are the SMTP settings?

Hostsmtp.unitpost.com
Usernameunitpost(always this literal value)
PasswordYour Unitpost API key(must carry emails:send)
Port (STARTTLS)587(or 2587 if blocked)
Port (implicit TLS)465(or 2465 if blocked)
From addressAny address on a verified domain

How do I set it up?

  1. Open the email provider settings

    In the Auth0 dashboard go to Branding → Email Provider (or Emails → Provider on older tenants) and choose SMTP.

  2. Enter your Unitpost credentials

    Fromyou@yourdomain.com (verified)
    Hostsmtp.unitpost.com
    Port587
    Usernameunitpost
    PasswordYour Unitpost API key
  3. Save and send a test

    Save the provider, then use Auth0's Send Test Email button to verify the connection.

  4. Enable the emails you want

    Under Branding → Email Templates, toggle on verification, welcome, password-reset, and other templates. Auth0 renders them; Unitpost delivers.
