Formatting posts for email subscribers

Our blog authors are complaining that posts received by email subscribers look awful, compared to the web version of the post. In particular, text doesn't wrap. Here's a sample post: http://blogs.elca.org/worldhunger/messiah-dives-deeper/ You can imagine the results, particularly in the Outlook client.

I realize formatting for a ranger of email clients is as difficult as being compatible with manner browsers. Any best practices or plug solutions that could help improve the formatting of post with graphics that email subscribers see?

Thanks, Paul
