What is the notification to actually receive an email notification when there is a new ticket/email in a department?

Can't believe I am having to ask this but I am not receiving an email notification when there is new tickets in a specific department even though I have every notification enabled under 'Agent Notifications' for this department.

It's really frustrating that everything seems to be really complicated to figure out.
