Email Segmentation is the process of dividing your email subscribers into various criteria. These are demographic, behavioral, psychographic and engagement-based segmentation. In the case of demographic segmentation, a customer’s age, location, and occupation is considered. You consider a customer’s purchase and browse history during behavioral segmentation. Psychological segmentation considers customers’ interests and hobbies. The active, inactive, recent and long-time customers are seen in engagement-based segmentation.
