I want to create a custom email template to send to my customers when their order has been shipped.
I want this email to include the tracking ID for the package.
I was thinking i could access the tracking ID in Administration > Notifications from the order_info variable (still don't know if it exists there)
I wanted to print all of it's values since it's an array but
Can someone that's more experienced show me the values stored in order_info or let me know if there's another way to find the tracking ID for each order
