Zaidesk provides you the default URL (subdomain.ziadesk.com) by using your entered zaidesk subdomain name. You can create your custom URL.

1. Go to Admin > Custom Domain > Custom Domain.
2. And after clicking the second option i.e. use a custom URL, enter your custom URL.
3. The message will be appeared in red color after clicking the [Check DNS] button.
4. You need to create a CNAME record on your domain registrar' CPANEL website to create the alias as below.

Now again click the [Check DNS] button and After clicking submit button, the custom domain is successfully activated. Now both custom and default URL are alias of each other. But when the custom domain is enabled then all your zaidesk account emails (customer and agent signup, tickets, notifications etc) use a custom domain.
