Domains
What is a custom domain?
It's the address for your website.
A domain (name) is most simply thought of as a website address.
When you create an account with Mossy, we setup your store on what's called a sub-domain. Essentially, it's your workspace name folloed by our domain eg. bob.withmossy.store. There's absolutely nothing wrong with this address and you can use it for as long as you wish.
Some companies may prefer to have something a bit more branded, like shopwithbob.com. That's where custom domains dome in.
