WooCommerce Email Template Customizer – Supported plugin?

Hi,
The website I am working on has this plugin installed/in use: Australia Post WooCommerce Extension PRO.
wpruby.com/plugin/australia-post-woocommerce-extension-pro/

I am entirely not sure, but would your plugin ‘WooCommerce Email Template Customizer’ work with the above noted plugin? It may not make a difference, or could cause an issue so I needed to check. I wanted to purchase your Email Customizer, so if you can help me understand it would be appreciated!
