Referral Program

Overview

A referral program turns your existing customers into an acquisition channel by rewarding them for introducing new customers. Referral apps like ReferralCandy and Referral Hero handle unique link generation, double-sided rewards (referrer and referee), fraud detection, and post-purchase email triggers without custom code. Only build a custom referral system if your tiering logic, CRM integration, or fraud rules exceed what these tools support.

When to Use This Skill

• When building a "give $10, get $10" refer-a-friend program
• When adding tiered rewards that escalate with the number of successful referrals
• When fraud from self-referrals or multiple accounts is draining referral reward budget
• When measuring referral program CAC versus other acquisition channels
• When integrating referral tracking with post-purchase email flows in Klaviyo
