How to prevent Automation Replies to be send to customer when tickets are created on our end?

Hi there! We are trying to set up an automated reply when a customer writes in. The automation reply should only be triggered when the customers send an email to us.

However, it seems that when we "Add Ticket" and "Submit and Send as an email" the automation reply will be triggered as well. How can we prevent this?

The current setting of our Automation Reply is: 

Execute on "Create" -> Criteria "Subject contains 'Job'" -> Action "Send Email Reply". 

I do not see any option on the execute where I can select only when a new email is sent in by customers then an automation reply will be triggered.
