Use a Custom Email Address

The most immediate advantage of owning a domain is to be able to customize your email address. Not all e-mail providers support this, but even if yours don’t you can also try relying on your Domain Registrar to provide an inbox and/or Email forwarding.

Having all your e-mail coming through an address that you own allows you to change providers without the hassle of notifying all your contacts and updating all your credentials. You just point your address to a different mailbox and start receiving new mail there.
