Configure Custom External SMTP Email Provider

Before you start

You can configure your own SMTP email provider to manage, monitor, and troubleshoot your email communications, and customize email templates.

Configure custom SMTP server

  1. Go to Auth0 Dashboard > Branding > Email Provider.

  2. Enable the Use my own email provider toggle.

  3. Select SMTP.

  4. Enter a From email address, and then enter your SMTP server's Host, Port, Username, and Password. Common ports include 25 and 587. Avoid using port 25 if possible, as many providers have limitations on this port.

  5. Click Save.

Test email delivery

You can now send a test email using the Send Test Email button. If you have configured everything correctly, you will receive a confirmation email. If you do not receive an email after a few minutes, please check your Auth0 logs for any failures.

SMTP makes it easy to set up test services that allow you to test that your setup is working without spamming your users. To learn more, see Set Up Test SMTP Servers.
