If an e-blast has an unusually high failure rate, notify the webmaster and/or the sender.

The notification should include instructions on how to see the failures and the error messages, how to discover the reason for a failure, and how to resend to the failed addresses.

The failure rate and who to notify could be user-configurable but should not default to nobody.

And URLs in the displayed Failure Text should be clickable.

This suggestion comes from having discovered that 15% of our e-blast last night was rejected by AOL and Yahoo. The error messages suggested resending, which worked. But if I hadn't stumbled over the failure rate while snooping around, I would never have known that we hadn't reached 15% of our members.
