Re: off site domain doesn't appear in the list of domain to use to create mail
Hi @mikali77. Welcome to GoDaddy Community! Usually, the domain would not appear in your cPanel account if it hasn't been added as an addon domain. You would need to do that first before you can set up email addresses for it. If you've already done that but the domain still isn't appearing, please get in touch with our support team so they can take a look at what's going on.
