How do I analyze the customer acquisition cost with discount campaigns?

As an e-commerce business owner, I'm struggling to understand how my discount campaigns impact customer acquisition costs (CAC). I want to develop a systematic approach to measuring the true cost of acquiring customers through promotional strategies, but I'm finding it challenging to track all the variables and calculate meaningful metrics. I need a comprehensive method to analyze whether my discounts are actually helping or hurting my bottom line, and how to optimize my marketing spend effectively.
