How UnBonMaillot automated 50% of CX and achieved 4x cost efficiency with Yuma AI

Introduction: From Garage to European Leader

UnBonMaillot began with a simple idea: bring the thrill of surprise and the love of sports together in a single box. What started in a garage, shipping a handful of mystery football jerseys, has evolved into Europe’s leading subscription box for sports kits. Today, UnBonMaillot delivers thousands of jerseys across football, rugby, and basketball to fans in France, Germany, Spain, and beyond.

With exposure from France’s popular TV show “Qui veut être mon associé” and a booming fan base, the company scaled from €1M to over €9M in annual revenue in just a few years. But with hypergrowth came operational challenges, especially in customer experience (CX). That’s where Alexis Ullmann came in.

Problem: A Need for Scalable, High-Quality CX

Alexis Ullmann, a seasoned e-commerce operator and COO at UnBonMaillot, joined at a pivotal moment. The company had hit €4M in revenue and was preparing to scale faster, with increasingly complex logistics, a new subscription model, and surging customer support volumes.

The team faced a familiar but urgent challenge: they were dealing with thousands of monthly tickets, many of which were repetitive WISMO ("Where is my order?") inquiries. This was further complicated by their multilingual customer base, which spanned several European markets. Meanwhile, they had limited internal resources to address these growing support needs.

It became clear that to support their ambitions, UnBonMaillot needed a solution, but also a partner that helps transform their CX for now and the future.

Solution: Why Yuma AI?

Initially, the team explored support automation software options like Klark and Achille. But as Alexis explains, their search for these led them to Yuma AI.

To ensure a smooth transition, Un Bon Maillot partnered with Let’s Care, a CX agency founded by Clara Zaoui, which specializes in email marketing automation (Klaviyo) and support optimization (Gorgias) for e-commerce brands.

Let’s Care already knew Un Bon Maillot’s workflows inside out, having led a reorganization of their processes and helpdesk prior to the Yuma integration. Acting as the bridge between Un Bon Maillot and Yuma, Let’s Care coordinated the onboarding, reviewed ticket flows, validated automations, and hosted follow-up calls during the first month to ensure everything worked seamlessly.

From the very first call, Yuma’s team handled the heavy lifting: mapping ticket flows, customizing automations, and progressively rolling them out, all while Let’s Care ensured the process was fully aligned with Un Bon Maillot’s goals and customer experience standards.

Together, Yuma and Let’s Care restructured Un Bon Maillot’s support processes, built a scalable ticket funnel, and introduced automations that grew week by week.

Yuma quickly integrated with Un Bon Maillot’s helpdesk and e-commerce stack. The CX automations started by handling WISMO and FAQ inquiries, then expanded to order updates, subscription changes, and multilingual support.

Within weeks, Yuma’s AI agents were fully resolving hundreds of tickets per week, freeing up the human team for higher-value work like handling escalations, addressing complex requests, and improving customer satisfaction.

   Yuma’s success team manages the minimal configuration and maintenance, meaning Alexis and the CX team don’t have to worry about AI performance or overhead.
