I have a custom Shopify product builder. The fields in it have name="properties" so after the order the seller sees in Orders all the fields that the buyer filled in. But the buyer receives a product by email without these fields, only its picture. Is it possible to send a purchase notification via email along with custom fields and not just with a product picture and price?
Are these properties being saved to the order as line items? If so, you should be able to display them in email notifications, see the help docs for more info.
