Set Up a Test SMTP Provider

Set Up a Test SMTP Provider

While working in your development or testing environment, we recommend that you use a test SMTP server so that you can:

  • Check that deliveries are successful
  • View how emails you sent appear to recipients prior to go live

You can either:

  • Set up your own SMTP server
  • Use a third-party service (see the Resources to Consider section for options you might use)

Once you have either your own SMTP server set up or a test service available, you can provide its credentials the way you typically would for a custom email provider.

Auth0 blacklists certain "false" domains commonly used during testing. Use real email addresses to avoid disruption or domain is blacklisted errors.
