Unfortunately, you can't. If you use Email Forwarding, emails sent to address@yourdomain.com will be forwarded to another email address of your choice, where you will be read them. You won’t be able to send emails from address@yourdomain.com since it is not really an email account, but a virtual email account.

In order to both send and receive emails using address@yourdomain.com, you will need to set up a full-fledged email account. You may review our available hosting plans to choose which one fits your needs; if you already host the domain on our web hosting plan, email is included with your plan.  If you host the domain with another host, check with them to see if email is provided in that email package.
