Stop email notification when ticket is manually created by agent

Hi there,

We use the automated email notification to inform a customer that a ticket is created when they email us. However, we often have situations where we contact the customer without them reaching out to us first. In these situations we manuelly create a ticket to start the contact.

Is there a way to prevent the email notification that a ticket was raised when the ticket was manually created by an agent and not raised by the customer themselves?

Thanks in advance!

Sam
