I have a form with a check box asking if the user would like to receive our newsletter. I have created a MC feed for it. I have left the Opt-In Condition box unchecked. I have checked the relevant checkbox for the item on MC, and changed the "Assign to group" dropdown to "If" along with the relevant logic.
What we're seeing is that if that user already subscribes, and have not ticked the box, they are being unsubscribed on MC. Is that the right behaviour for the MC Feed?
Thanks very much!
