Case Study: Postmates boosts user stickiness and triples marketing efficiency with Amplitude

How Postmates uses Amplitude and Braze to Build an Engagement Strategy that Gets Users to Stick

Postmates is an on‑demand delivery platform that connects customers with local couriers to deliver anything from food to groceries. Their Growth Marketing team faced a product challenge: develop the right external triggers and messaging to make users repeatedly see the platform’s value and increase customer stickiness without harming the experience.

By integrating Amplitude for behavioral analytics and Braze for omni‑channel messaging, Postmates ran coordinated product‑marketing experiments (notably a Bachelorette campaign) to target users with timely email, push and in‑app messages and iterate in real time. The approach drove substantially higher engagement (single‑channel messages lifted engagement by 179% versus no messages) and improved marketing efficiency, with Postmates reporting a 3x improvement in marketing spend efficiency and measurable LTV gains.
