The online Help section within the Configurable Unsubscribe page mentions: If any product(s) is restricted to the account, then those are not displayed in this list. How is this configured?
If users want to restrict products from appearing on the unsubscribe page, populate the field Restricted_Products_vod of the corresponding Account with the restricted product name. The product is not displayed in the product list on the unsubscribe page.
