Blog to email gateway?

In talking with my mom a few weeks ago, I realized that readers of my blog know more about what's going on than my family does. Writing individual emails to them isn't going to happen, so I'm looking for a blog to email gateway. It should:

  1. Monitor a specific category in the blog for new posts...
  2. Create a templated email message from each new blog post...
  3. Send that email to a list of recipients...

Anybody know of something that does this??
