Which segments deserve no discount but reassurance instead?

As an e-commerce manager, I'm realizing that not every customer segment needs a discount to convert. Some visitors are actually more likely to purchase when given the right type of reassurance or value proposition. I want to understand which customer groups might be better served by strategic messaging, trust signals, or alternative incentives rather than immediate price reductions. My goal is to optimize conversion strategies without unnecessarily cutting into profit margins by indiscriminately offering discounts.
