Users who pay for the domain/mapping “Upgrade” at WordPress.com, can also apply for a matching email from Google Aps. I found the process a bit daunting; I had to make note of several longish codes during the setup process, switch between screens, and had to wait a few days for the account setup, but I finally have an email that matches my new domain here. I’d prefer a drop-in mailer to further deter spam, but Gmail (part of Google Aps) has excellent filters. I’ve put the contact information on my about page, but I think I’ll explore some form options before I create a link.
