I have a new favorite Drupal module: Reroute Email I setup a site a while back that allowed for the client to bulk-email their users. I generally try to sway people from this lest they get on a spam list from unforgiving users, but I digress. The e-mails were sent in plain text, and incredibly boring. I did include an unsubscribe link as a condition of creating the bulk-email process, but other than that it was very... drab. So said client comes back a few weeks ago and asks if we can "jazz up the email a bit". Since this site has been live for close to two years with only critical updates being applied, I have long deleted the dev site.
