- Description: Configure custom spam filter settings, to prevent specific email domains from signing up to your publication.

As part of Ghost(Pro)'s managed hosting service, we proactively monitor and block spam signups automatically for you, whenever we spot patterns of abuse across our network. 

You can also configure your own spam filtering settings from within Ghost Admin, in the **Settings → Membership → Spam filters** area, to prevent specific email domains from being able to sign up on your site.

To prevent an email domain from signup, enter in the domain you want to block, and click **Save**.

💡

Add one domain per line, e.g. `spam.xyz` to block signups from email addresses like `hello@spam.xyz`.
