A good example use case for this feature is when a merchant sends a supplier notification and wants a visual confirmation of that on the order in the Shopify admin. Let's say clothing brand that specialise in t-shirts has a supplier called Acme Caps who ship all their caps for them. In this scenario an email notification would be set up to trigger when a product type of
cap is found on the order. To ensure customer service staff know that notification has been sent to the supplier then adding the tag
Acme Notification Sent to the order will be a big help.
