By dividing your email list into smaller groups based on characteristics such as demographics, behavior, or preferences, you can tailor your messaging and content to better suit the needs and interests of each segment. This can lead to higher open and click-through rates, increased engagement, and improved overall campaign performance. Additionally, targeted campaigns are more likely to convert subscribers into customers, increasing ROI.
