Hi @tltroy - I’m not sure if SailPoint lists all of the OOTB notifications that are sent in one centralized location. Your best bet may be to review the Lifecycle Manager workflow docs here and here as several notifications are sent during LCM processes.
As an alternative, have you tried using a custom EmailNotifier class? This would allow you more granular control of what emails are sent by IdentityIQ. This doc is a good reference to configuring this, you would just then need to tailor it to your use case by determining what emails to filter out.
