SQL Server 2008 :: Failed Task In Maintenance Plan Not Being Reported By Database Mail

I have inherited a server on which is a maintenance plan with two subplans on different schedules. In each subplan there are Execute T-SQL tasks with scripts for index rebuilds. Each task is set up with a Completion arrow to the next task and a Failure arrow to a Notify Operator Task. I was asked to add a task for index rebuilds to a specific subplan for a specific database, which is what the other tasks also do. I discovered that my task was failing but the others were fine. No notification was sent about my task failing even though the job is marked in MSDB as a failed job. I have sent a test email using the "Send Test Email..." option when right clicking Database Mail in SSMSand I receive an email so I know Database Mail works.

I set up a test job to model the index job that I can't get notifications from. I have two T-SQL tasks that just select the top row from a small table. The first task has a syntax error that I did so it would fail. I have a failure arrow to a Notify Operator Task and a Completion arrow to another T-SQL task with no syntax error which has a Success arrow to a Notify Operator task. As expected, when I execute this job I receive one failure email and one success email.

The only other troubleshooting step I know to try is to add a Notify Operator task before my failing task. That Notify Operator task will hopefully fire to tell me that the previous step was successful. I am not having problems with the other steps so I was just thinking I would try to get the subplan to send me a success email about one of the steps that has been working fine.
