Presale Question (Using Placeholders)

Hello,

when i buy the Plugin “WooCommerce Email Template Customizer” am i able to use the short codes from Woocommerce Shipment Plugin?

Tracking Number: {{order-_wc_shipment_tracking_items:tracking_number}}
Tracking Provider: {{order-_wc_shipment_tracking_items:tracking_provider}}
Date Shipped: {{order-_wc_shipment_tracking_items:date_shipped}}
Custom Tracking Provider: {{order-_wc_shipment_tracking_items:custom_tracking_provider}}
Custom Tracking Link: {{order-_wc_shipment_tracking_items:custom_tracking_link}}

Right now it doesnt work in my emails. Is it right that it only works with Pro Version?
When it works with Pro i will buy pro version.

Thanks for your help!
