I frequently receive alerts about maintenance jobs being scheduled. While I do want to receive those notifications, the title says “Alert - X - [date]” like all the other real and serious alarms I have. So filtering those maintenance warnings and real alerts that require immediate action is hard.
It would make much more sense to include the type of the alert in the email subject (e.g. “Alert - X - maintenance scheduled” to make things easier or at least rename the maintenance alerts to warnings.
