How do I get a domain email?

The past few days I have set up a blog on my domain using wordpress. I’ve been really happy with it and when I get a few more posts I am going to start promoting my blog. In order to make it look really professional I want to get a custom domain email. Something like [email protected] that I can pass out to people instead of my gmail account. I think it will help make a professional impression and ideally it will just forward to my gmail account so I don’t have to check two email accounts a day. If anyone knows a plugin or method to do this it will be much appreciated.

Likewise since I have just built my site any constructive criticism will also be welcomed.

Thanks guys.
