Activating 'Send Job Application Notification' ESS job in PROD, prevent back-dated emails?

Summary:

We are facing an issue with email notifications in our Oracle Fusion HCM Recruiting module. We have a ticket from a customer about emails not being generated for candidates in ORC.

Upon investigation, we found that the scheduled ESS job, 'Send Job Application Notification', was not active or scheduled in our Production environment. We have since activated and scheduled this job in our Test environment. The emails are now being sent correctly to our test IDs, and we have confirmed the functionality.

Our main concern is how to safely activate this job in our Production environment. We do not want to trigger and send a backlog of old or "back-dated" email notifications to a large number of candidates when the job is first run.
