Error When Customizing the Verification Email Redirect To Field for Non-Enterprise Auth0 Tenants

This article explains why an error occurs when attempting to update the Redirect To field within the Verification Email (Link) template. When attempting to save the template with the following value in an Auth0 Essentials tenant:

{{ application.callback_domain }}/sign-in

The following error is displayed:

Customizations for resultUrl are not allowed for non-enterprise tenants.

• Auth0 Essentials plan
• Verification Email (Link) template
• Tenants created after May 5, 2026

This is the intended behavior. All tenants created after May 5, 2026, at 00:00 Coordinated Universal Time (UTC) are restricted from setting the result URL in emails unless the tenant is on an Enterprise plan. 

Choose one of the following options to resolve this restriction:

• Utilize an older free tenant created before May 5, 2026.
• Upgrade the tenant to an Enterprise plan.
• Utilize a private tenant located outside the public cloud.
