BEN: Set Up Communication Type Trigger in Benefits to Send Email

We are trying to set-up a Communication Type Trigger in the Benefits Manager responsibility to send an email to an employee when they complete their Open Enrollment.  We followed the steps provided in the "Oracle® Human Resources Management Systems Compensation and Benefits Management Guide" to set up a Communication Type Trigger but the email is not being sent.  Are there additional steps that need to be taken in addition to defining the Communication Type in the Benefits Manager responsibility?  Has anyone done this?
Thank you in advance!
