Referral Program

This walks you through building referral and affiliate programs with actual frameworks for deciding between them. It covers the full loop from trigger moments to incentive sizing (there's a formula for calculating max reward based on LTV), plus specifics like cookie duration and commission structures. The Dropbox and Morning Brew examples show what worked and why. Use this when you're trying to turn customers into a growth channel or need to figure out if you should pay 20% or give away free months. It's basically a referral marketing playbook that assumes you want numbers and structure, not just vague growth advice.
