Auth0 Email Services

Auth0's built-in email provider is not supported for use in a production environment and should only be used for testing and has several restrictions:

You will not be able to use any of the email customization features. The content of the emails sent for testing will be restricted to the format of the existing templates.
All emails will be sent from a predefined from address (no-reply@auth0user.net).
You will be restricted to sending no more than ten emails per minute, regardless of email type.
Your ability to send email from your tenant may be reduced (or even temporarily blocked) if your emails result in high bounce rates.

To remove these restrictions in your testing or to set up your production level emails, you have to set up your own email provider:

After you have configured your own email service provider, use the Emails Dashboard to customize your emails beyond the existing templates.

If you have an Auth0 database connection, there are several emails that are part of its authentication flow including verification emails, welcome emails, change password emails, and breached password and blocked account emails.

The MFA enrollment email can be sent to users in any type of connection.

If you have an Auth0 Free Subscription plan, email workflows, and using the custom email provider features are available however, a paid subscription plan is required for email customization. See the subscription pricing page for more details.
