Email and custom url's

If you wish to use a custom URL for your email address, and either do not want to use the email hosting provided by your domain registrar or email hosting is not provided, you have a couple of options.

Regardless of the option that you choose, you will need to create an MX record in your DNS settings similar to how you created a CNAME record for the custom domain. You'll need to follow the instructions provided by the email host to create the appropriate MX record in your DNS settings.
