When using Notify in Zoho Desk under Agent Notifications there should be an option to notify the agent ONLY when another agent triggers the notification rule. 

Example: If the notification for the agent on a new comment is on, it will notify ME when I am the one writing the comment! 

This is causing a LOT of emails to trigger. A notification is only supposed to trigger to direct the agent to go to Zoho desk as there is something waiting for them
