I am looking to notify specific Requesters that a new hire is coming on board. These requesters will be in responsible for creating accounts for said new hires. 

I have a template setup for our HR team that will come to the IT team when someone is initially hired. I need to be able to perform a task that will notify users that are not technicians so that they can begin creating the accounts for the systems that they are responsible for.

What is the most efficient way to do this? Thank you for the help.
