I am trying to register a domain with Shopify but it seems like it has been attached to a previous account of mine who's trial period has expired. Now I have created my domain specific email address. My domain is www.popnosh.com and my email address is email@example.com. I want this email to be attached to my domain now.
Chris from Shopify here. If you're not able to log into the old account to remove that domain name, you should contact one of our Gurus at firstname.lastname@example.org for help, or by using the live chat feature found here: https://help.shopify.com/questions
We look forward to hearing from you, have a nice day.
