Free users are either future customers or advocates. It helps to categorize them based on their behavior rather than just how long they have been using the product. Look for patterns like how often they engage and which features they use. Engaged free users are more likely to convert or recommend your product. If some users are not adding value, guide them toward conversion with upsells or incentives. A referral program can also unlock value from free users. The goal is to balance engagement with sustainability, giving value to those who might become paying customers while minimizing the drain on resources.
