When you configure an email workflow within Freshdesk, you would want to be notified about any updates made to tickets you are working on and updates made to your active tickets queue. Freshdesk has default email notifications used to send alerts when a ticket is assigned to an agent, a group or when it is created in your portal as such. Actions such as when a client replies, a note is added, or when the ticket is resolved - are notified to the agents as well as requesters. 

Please navigate to the Admin --> Helpdesk productivity --> Email Notifications --> Turn ON/OFF each notification under your preferred tab.
