These are the basic steps to follow:
- Install WooChimp, enter your MailChimp API key and check “Enable Ecommerce 360”
- Enable subscription on checkout so customers are added to one of your mailing lists
- Wait for at least one sale of the product in question (for it to appear on the MailChimp side)
- When creating an autoresponder, on the first step select your list, then select “Send to a new segment” and create a condition “Product Purchased” | “is” | “Your Product Name”
