I got sick and tired of having jobs fail without being notified, because the job was marked as "in process" and never completed its failure, so a failure notice wasn't sent. So I wrote the following script to find all of the jobs that are enabled and email me the last date associated with the job and its success/failure status. This way if a job is really hung up because of a SQL bug, I get notified and can see that its last success date was in the past so I'm clued in to go and take action.

from msdb.dbo.sysjobhistory where job_id in (select job_id from msdb.dbo.sysjobschedules) and step_id = 0 group by job_id) Outcome on Outcome.Job_id = sj.Job_id and sj.enabled = 1
