A subdomain is an extension of your domain name. For example, one.store.com and two.store.com are subdomains of the store.com domain. If you own your own domain, you can verify subdomains in Shrink It to use as part of your landing page URLs.
To verify a subdomain and use it on a landing page, you’ll need to complete a few tasks in your domain provider accounts. Here's a brief overview of this process.
Create a CNAME record in your domain provider's domain manager.
