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?
| Host | smtp.unitpost.com |
|---|---|
| Username | unitpost(always this literal value) |
| Password | Your Unitpost API key(must carry emails:send) |
| Port (STARTTLS) | 587(or 2587 if blocked) |
| Port (implicit TLS) | 465(or 2465 if blocked) |
| From address | Any address on a verified domain |
How do I set it up?
Open the email provider settings
In the Auth0 dashboard go to Branding → Email Provider (or Emails → Provider on older tenants) and choose SMTP.
Enter your Unitpost credentials
From you@yourdomain.com (verified) Host smtp.unitpost.com Port 587 Username unitpost Password Your Unitpost API key Save and send a test
Save the provider, then use Auth0's Send Test Email button to verify the connection.
Enable the emails you want
Under Branding → Email Templates, toggle on verification, welcome, password-reset, and other templates. Auth0 renders them; Unitpost delivers.
