Enable Post Acceptance Section Submit Notification
Administration > Manage Site Settings > General Settings
If you have designated an Application Contact in the Application > General Information setup for your application form, then you have the option to send a notification email to that contact every time an applicant completes and submits a Post Acceptance Section. That section must have been created using the Post Acceptance section type. The email that is sent is in the Notification Center > System Email Template > Application: Applicant Submit Post Acceptance Section.
General Settings option:
Select Yes to send the emails once the applicant clicks Submit for that Post Acceptance Section. Otherwise, select No if you do not want the Application Contact to receive an email.
