I do a lot of email marketing through Communications Wizard. Occasionally, for whatever reason, the email gets timed out and all of the emails do not go through. In the messages hub, it would be nice to have a category "Unsent" so I can figure out which messages didn't go through and resend them. Right now I have to go to Messages hub, filter to find out which ones were sent, export a list, print it out. Then I have to go through Communications Wizard, recreate the email to send, unselect all and select the names that didn't go through. They aren't always sent in alphabetical order. If I could just filter in Messages to messages that were unsent, life would be so much easier.
