Google Apps for Domains is an incredibly powerful and free set of tools that lets you set up Gmail, Calendar, Docs and Spreadsheets, and many other Google Apps for your own website. Sure, you could open a separate email account for your website mail, but why not harness the power of Gmail for all your email needs? Not a plug. Well maybe. For example, I have robert@robertdyson.com set up so I can use the Gmail interface to do all my emailing. Look out for a post reviewing Gmail and Google Calendar soon. In the meantime, they rule.
