We have a customer only portal of our site that is hosted outside of HubSpot. We’ve found that through the API you can identify if someone has Unsubscribed All. In that case we want to show a message that says that they are unsubscribed and if they want to manager their preferences to click a button. This button would, ideally, send that specific customer the re subscription email that has the Hubspot generated link for them to update preferences.
Does anyone know how to do this or another work-around to getting this done?
