Sending alerts for other events is definitely something I've thought about as well and plan to add in some way. I haven't quite figured out the best way to enable optional features like this -- perhaps a separate email address or something in the body? As you hinted, I'd like to keep things as simple as possible and avoid signups if I can (criminal, I know), at the very least for the basic feature of being notified on delivery.
