I am new to Zen Cart. I have not installed it on my site yet.

During my investigation of shopping cart systems I noticed some customers on a forum being impressed with a vendor feature. When they order a product they automatically receive an email confirming the product order and a Fed Ex tracking number. Is this apart of Zen Cart, a module or a seperate software? I would love to implement this feature with my Zen Cart install. However, I do not know what it is exactly.

Has anyone heard of this feature? Thank you for helping.
