About Fondue
Fondue (CashBack by Fondue) is an incentive platform, now part of Postscript, that helps ecommerce brands boost conversions without eroding margins. Instead of traditional coupon discounts that apply on every use, Fondue’s CashBack lets merchants offer higher-value incentives while only paying out when it truly matters. After purchasing, customers choose their reward—store credit or a prepaid award card—improving satisfaction and list growth while protecting profits. With built-in A/B testing, Fondue proves uplift before scaling and has driven gains like +31% SMS/email signups, +20% welcome series revenue, and higher contribution margins, all via simple UTM-based integrations with existing email/SMS and onsite flows.
