Closing old reqs, will that auto send emails?

Summary

closing old reqs

Content

I inherited a system where reqs were never filled or closed.  I need to go in and close all the old reqs. Will this auto email candidates that applied for those reqs in the past? Or does anyone know where in Customize Recruit I would go to look to see if there is an on/off switch for that? I want to make sure no one gets emails on reqs that have been open for years!

 

Thank you all~
