Tag orders with free shipping in Shopify by using Arigato Automation
Track orders with free shipping to better understand customer preferences.
This simple automation fires when a new order is created in your store. It then checks to see if the order's shipping cost was equal to $0. After that, it adds a tag to the order called "Received Free Shipping."
This automation is great if you want to have an easier way to organize your orders by shipping cost.
