Reasoning
Across the sources, the predominant characterization of HubSpot's workflow automation is high/advanced complexity. Several reviews explicitly describe it as high or advanced, with mentions of multi-path workflows, if/then conditions, drag-and-drop interfaces, and the need for paid plans for advanced capabilities. While a minority cite low or easy, these signals are less frequent and generally lower in confidence. Weighted by source emphasis and consistency, the consensus aligns with high complexity.
