Quizplus · Accepted Answer

Cost per order (CPO) is the most commonly used effectiveness measure in direct marketing because it directly relates to the revenue generated by each order. CPM (cost per thousand) is a measure of reach, not effectiveness, while CPMH (cost per man-hour) is not commonly used in direct marketing. SDN (sales per database name) is not a common effectiveness measure in the industry.
