This study reviews three primary purposes of causal machine learning (CML) in marketing, merging impact
evaluation of marketing interventions with machine learning algorithms for learning statistical patterns from data.
Firstly, CML enables more credible impact evaluation by considering important control variables that simultaneously
influence the intervention and business outcomes (such as sales) in a data-driven manner. Secondly, it facilitates the
data-driven detection of customer segments for which a marketing intervention is particularly effective or
ineffective, a process known as effect moderation or heterogeneity analysis. Thirdly, closely related to the second
point, it allows for optimal customer segmentation into groups that should and should not be targeted by the
intervention to maximize overall effectiveness. The discussion is grounded in recent empirical applications, all of which
aim to enhance decision support in marketing by leveraging data-driven evaluation and optimization of interventions
across different customer groups.
