How to exclude a product or category from the coupon

Hi, using the automatic coupon feature in Acymailing, it is not possible to exclude a product or category from the coupon (I have already asked their support team). I would like the coupon to be activated on all products except for one product or category. Specifically, I am referring to a product that can only be purchased with recurring payments. Is there a way to exclude a product or product category from any type of coupon? Obviously I know that if I create a coupon in Hikashop I can define the categories to which it can be applied and can, consequently, exclude others. But with the email marketing automation system, via Acymailing follow up, this function does not exist. Can you help me find a solution? For example, is there a function on the product page to disable any coupons for that product? I don't think I've seen it, but I'm asking anyway.

By the way, if a coupon is created with Acymail with a 10% discount on all products, therefore including a product with a recurring payment with PayPal of 100 euros each month, what value will be applied to the renewal of the second payment, 90 euros or 100 euros?

Thank you.
Best regards
Francesco

Thank you,

In most cases, people who purchase on my site with recurring payment do so in an order with a single product. So I ask if I understood correctly: if the product has a price of 100 euros and is purchased with a 10% discount coupon for 90 euros, will the next recurring payment be 100 euros?

Thank you

Thanks a lot
