Find the smart campaign you want to add the SMS flow to. Click the Flow tab.
Drag over the flow, for example, Send SMS Message. Select the SMS Message and the Vibes list from the drop-downs.
The Vibes List selector acts as a further filter to the audience already identified in the smart list to target only those leads who belong to that Vibes list.
