It's possible to have different email templates for every different product category. For instance, kitesurfing and SUP can have different emails. Normally, the default templates are used for every category.
Create email per category
If you want to make changes for a specific sport, select the product category you want to edit and select a template. Now 'enable' this template and adjust the text to your liking.
Disable emails
Go to the product category in emailtemplates, click on the email you want to disable & disable the email in the right top.
