The condition node checks the full MDP unified profile — loyalty data, web behavior, purchase history. Sendwave can only check its own profile data.
Scheduled campaigns → Read Audience. Win-back flows triggered by time-since-purchase → Audience Qualification (fires the moment someone enters the lapsed segment).
Wrong entry type = journey fires too often, not often enough, or at the wrong time. Document this mapping for every Sendwave flow before you start rebuilding.
