Email segmentation in email marketing is the process of dividing an email subscriber list into smaller groups or segments based on specific criteria such as demographics, behavior, interests, location, or lifecycle stage. This allows marketers to send more personalized and relevant content to each segment rather than generic emails to the entire list
. By grouping subscribers who share common characteristics, email segmentation helps deliver targeted messages that resonate better with recipients, increasing engagement, open rates, click-through rates, and overall campaign effectiveness. For example, segments can be created based on age, gender, purchase history, or engagement level, enabling marketers to tailor content to the unique needs and preferences of each group
. Segmentation is a fundamental tactic in email marketing that, when combined with personalization (customizing content for individuals within segments), can significantly boost return on investment by making emails feel more relevant and valuable to subscribers
. In summary, email segmentation is a strategic approach to organize and target email recipients into focused groups to improve the relevance and performance of email marketing campaigns
