It's important to keep in contact with your future visitors/customers, and the easiest way to do it is via emails. So, managing your email accounts becomes a priority, and cPanel's email manager is the right tool to use in order to create/edit new email accounts, forward emails, create and manage mailing lists and auto-responders, etc. You can find video tutorials in your cPanel about this.
Also you can order various corporative email packages from us to use with your domain.
