How do I turn on notification for checklist tasks assigned via HSDL load?

I am getting ready to assign a survey to some eligible associates via HSDL spreadsheet loader but noticed that the assigned email / bell notification is not triggered. Is there specific settings I need to do to make sure associates are notified of the checklist task they need to complete?
