Different e-mail per product category

Hello,

I am trying to send separate emails for each product category. For this, I am using the “rule section” on the right side of the screen. However, it is not working. If I don’t set a rule for the product category, the regular emails are sent. But if I set a rule, for example, this template is for product category “A”, WooCommerce’s default email is sent instead (not from this extension), so not the email I made.
