You must be the legitimate owner of the domain name you want to use and share access to your domain management account with us.
We will log in to your DNS control panel and create a new record for [your domain] CNAME zetaprints.com as described in this help post.
Once the DNS record goes live we will go to this new domain name and log in to your web-to-print portal to assign the domain name.
Would you like to give it a try before purchasing this service? We are happy to help you if you don't want to do it yourself.
