In regards to customer promotions, which statement is true?

The statement that a customer can only use promo codes linked to their referral is accurate because it aligns with how promotional codes are often structured in marketing campaigns. Referral-based promotions are designed to incentivize specific consumers, encouraging them to bring in new customers through unique promotional codes associated with the referrer. This helps businesses track which existing customers are effectively driving new business, creating distinct promotional codes for each referral expands the capacity to analyze performance and success accurately.

This structure not only helps maintain loyalty among existing customers but also targets new customers in a much more personalized manner, contributing positively to customer acquisition strategies. Companies can limit the usage of these codes based on who referred them to ensure a more organized promotion and reward system.

The other options offered do not hold true in this scenario. Promo codes are often specific and can be directly linked to referrals for tracking purposes, rather than allowing general usage across all customers or campaign partners. Additionally, promo codes can indeed be tracked as part of a comprehensive marketing strategy, facilitating analysis and optimizing future promotions.
