Post-purchase referral
Marketing mechanic where the customer receives a unique referral link immediately after their order, which they share with friends and family in exchange for a reward on generated sales.
Post-purchase referral differs from 'classic' referral by its activation moment: the link is generated when the customer has just paid, when their emotional engagement with the brand is at peak. Our assumption: at this precise moment, the propensity to share is significantly higher than with an email solicitation several days later.
Modern platforms (Social Pay, Mention Me, ReferralCandy) offer sharing directly from the order confirmation page (on Shopify, for example). The referrer doesn't need to create an account, enter an IBAN, or wait — the link is ready. The reward varies by platform: instant cash cashback to the card with Social Pay; discounts, vouchers, store credit, or other rewards elsewhere.
2026 estimates from our model (assumptions, not measurements): 62% post-purchase share rate across verticals, 74% in beauty, 41% in food. In this model, blended CAC (Meta + referral) would drop from €55-70 to €14-26 after 6 months of activation — a target to validate on your own data.
