Active contacts

Contact cannot enter a campaign unless they satisfy a goal. Making a purchase or raising a tag are a couple of the common goals used. Having fulfilled the requirement of the goal to begin the campaign, they are then run through, step by step, the campaign sequences as it is designed.
