Sep 10, 2025
Overview
This article provides steps to resolve an issue where customized email template changes are not reflected when testing email delivery using the Try button after configuring a Custom Email Provider.
Applies To
- Custom Email Provider
Cause
One possible cause of this issue is that the From email address is not correctly configured in the custom email template settings.
Solution
If custom email template changes are not reflected in delivered emails when using a Custom provider and the template is enabled:
- Verify that the From email address is correctly configured in the custom email template settings.
- A custom From address in the email template configuration is required to render custom templates.
NOTE: Any "From" email address that contains either of the domains below will not send custom templates for security reasons:
@auth0.com@auth0user.net
