I'm not quite sure what you mean. If you want to use domain email addresses such as [email protected], there are several ways to do this:
1) Your web host can provide your domain email if it is included in their web hosting plans.
2) You may use our Dynadot DNS if you have a web server and an email server set up to serve your domain.
3) If you decide to use our Domain Forwarding or Stealth Forwarding options, you can have all your domain email forwarded to a single email address. Please note that some email services such as Hotmail, may mark those emails as spam, and they may filter it out automatically unless you put the us on your safe list.
Again, it depends on how you are setting up your domain and the web hosting for your domain.
