What is one of the three best practices for creating a successful segmentation strategy, aside from having a clean database?

Understanding both implicit and explicit data is crucial for developing a successful segmentation strategy. Implicit data refers to behaviors and actions that indicate a subscriber's interests or preferences, such as website visits, email engagement, and purchase history. Explicit data, on the other hand, consists of information that subscribers directly provide, such as demographics, preferences, and opt-in details.

By analyzing both types of data, marketers can create more refined and meaningful segments of their audience. This deep understanding allows for personalized and targeted communication, ultimately leading to higher engagement rates and better alignment of content with subscriber needs. The ability to craft messaging that resonates with specific groups enhances the overall effectiveness of email marketing efforts, driving conversions and fostering customer loyalty.

The other practices mentioned, while valuable in their own right, do not directly speak to the foundational aspect of segmentation that comes from a thorough grasp of both implicit and explicit data.
