Verifying your domain lets us confirm that you own that domain and can help you manage access to your account.
Once you've verified your domain, users that are not a part of your team will be prevented from signing up with email addresses belonging to that domain. Verifying a domain is also required to enable other Enterprise features such as Single Sign-On.
Note: This feature is only available for Nitro Productivity Suite Enterprise customers.
Your first domain will already be added for you and should appear in your list of domains.
