We find WooCommerce to be a very common eCommerce platform for our clients and they get very excited about the fact that Klaviyo empowers them to send notification (especially over text) - as being able to offer shipping updates via text creates a significant appeal for customers to give SMS permission.
Imagine our surprise and disappointment to find that Klaviyo does not provide any triggers on shipping status from a WooCommerce integration. Rather a 3rd party integration is necessary.
This would be an awesome feature to include.
