Building a complex query structure typically involves multiple steps:
Data Collection: Gather detailed data on your subscribers, including their behavior, preferences, and demographics. Segmentation: Use this data to create segments that reflect different audience groups. Define Criteria: Establish specific criteria for each segment. For example, you may target users who have opened at least three emails in the last month and have made a purchase. SQL Queries: Many advanced email marketing platforms support SQL, allowing you to write custom queries to extract precise segments. Testing: Always test your queries to ensure they return the expected results.
