I have a case where we have optional mailing lists for our members, but also a mandatory list that members must not be able to unsubscribe from (a smart group that looks for active members -- our master list of members -- which we use to contact them about urgent issues). A condition of membership is that they need to remain on this list.
But, when I send a mailing with the {unsubscribe} placeholder, members see all the lists they are on, including the master list, which they can then unsubscribe from.
Is there a way to prevent a mailing list from being displayed on the Unsubscribe page?
