If you like Gmail, and there is a lot to like, you will love Google Apps Mail which is basically Gmail for your domain. Sure you can add in your domain to Gmail, but it is not the same as having email coming from your domain. The best way I have found to manage my domain emails are through Google Apps.
Last week when I was on the weekly RETechRadio show I mentioned Google Apps Mail as a tool agents should be using. I was asked about the difficulty of setting up an account. In this short video I show how easy it is to actually set up the account.
In this video I use Godaddy as my domain registrar. If you use someone else or have your site hosted somewhere else you can find directions here.
