Email Domain Blocklist

The Email Domain Blocklist allows you to prevent users from accessing your experience if they sign up or play using an email address from a blocked domain.

This feature is especially useful for reducing fake registrations, preventing the use of disposable email providers, and ensuring higher-quality participation.

You can configure the blocklist to show users a custom title and description when their email domain is not allowed.

You can define:

A title displayed to the user when their email domain is blocked
A description displayed underneath the title to provide additional guidance
A list of email domains to block (one per line)

A link to a recommended list of disposable email domains is provided directly underneath the textarea to help you populate your blocklist quickly.

Please note that while this option blocks email addresses from the domains you specify, it won’t prevent users from registering with a different domain you have not blocked.

Where prizes or restricted access are involved, it may be helpful to explain acceptable email requirements in your terms and conditions.
