The Lists tab gives you a bird's-eye view of all 96 funnels and their autoresponder connection status. Each funnel shows a color-coded status indicator:
Green (Connected), The funnel has both a provider and a list assigned. Opt-in forms will work correctly.
Yellow (Missing List), A provider is assigned but no list/form ID is set. Subscribers may not be added to the correct list.
Red (No Provider), No autoresponder is configured for this funnel. The opt-in form will not work.
