We have a couple of jobs that run on a nightly basis or are only started through the API. For these kinds of builds it would be great if I could get a notification email when they fail. Because they are not required it can (and did) happen that these jobs failed silently without anyone noticing until after the next release.
With the current notification settings I would get emails for all the failed builds of my branches (thanks, GitHub is showing me that already) or simply everything that ever happens (good look spotting this error in there). What I want are notifications for the jobs that don't get this kind of visibility.
