Does Web Hosting Economy service support a domain from another registrar?
I am planning to buy Web Hosying Economy service for building an email server. I have a domain registered from another company. So I don't want to using free domain of this service. Could I use domain from another registrar with this service?
You can use GoDaddy hosting with domain names not registered with GoDaddy.
I do want to point that that Web Hosting is specifically for hosted websites, and would not work as an email server. If you are planning to only use GoDaddy for email, I suggest purchasing an email plan instead.
