# Improved "Add new domain" dialog

![New add domain dialog](2025-11-09-improved-add-domain-dialog.png)

We've improved the "Add new domain" dialog, which now shows examples of what is as valid domain name and what is not, for example making it clearer that the `www.` prefix should not be present.

There is now also a link to the [Subdomains](/docs/domains/subdomains) documentation page, which explains how DMARCwise and the various protocols work with subdomains, and when you should add them separately in the dashboard.
