Hi @GabeF :
To stop these "Change Request Commented" notifications from reaching the CIO, the cleanest approach would be to handle it at the user level. Since these emails are usually triggered because the CIO is listed on the record's Watch List or tagged as an stakeholder, the CIO (or an admin impersonating them) can simply navigate to Preferences > Notifications from their profile menu in ServiceNow, find the Change Request category, and toggle off the "Change Request Commented" email notification. This stops the noise for the executive without altering core system workflows for the rest of the team.
If you prefer a platform-wide administrative fix—for instance, if the CIO is automatically added to Watch Lists by default but shouldn't receive comment updates—you can adjust the notification definition directly. Navigate to System Notification > Email > Notifications, open the "Change Request Commented" record, and check the Who will receive tab. From there, you can either remove the CIO or their group from the explicit recipients list, or add an advanced condition/script filter (sys_id is not <CIO_sys_id>) so the system skips sending this specific notification to their address.
