Ready to optimize your tracking performance ?
Why choose Addingwell? Mainly for the simplicity of hosting management. It was truly one of the most important points. Replication issues were key: for example, we have sites in the U.S. and Europe.
Chantelle is a historic French lingerie house, 149 years old, with 3,500 employees. The company controls its entire value chain, from raw materials to distribution, and operates six major e-commerce sites, including five in Europe and one in the U.S. These platforms gather an average of 1.25M unique visitors per month, creating a crucial need for reliable, compliant, high-quality data.
In an environment marked by strict GDPR requirements, a complex technical architecture, and the growing impact of browsers and ad-blockers, Chantelle needed to modernize its tracking ecosystem while strengthening transparency and user protection.
CHALLENGE
Before deploying Didomi and Addingwell, Chantelle faced several major challenges:
• Unstable, hard-to-maintain server-side infrastructure:
The company was already using a server-side setup, but it was fully custom-built, complex to maintain and requiring internal DevOps skills. On top of that, legacy issues, limited flexibility, and strong dependency on technical teams made matters worse.
• Critical impact of ad blockers:
Ad blockers were blocking the entire client-side Google Tag Manager, preventing the collection of a significant part of traffic, blocking consent display, and severely degrading analytics and attribution.
• Lack of international flexibility:
Latency gaps between U.S. and EU sites, due to a server-side setup deployed only on EU servers, were harming measurement, ad performance, and user experience.
• Insufficient transparency with the previous CMP:
The former tool did not allow for sufficient granularity, partner-level management, or clear and maintainable documentation.
Chantelle wanted to go much further in transparency, an essential value for a lingerie brand where trust is central.
Solution
To address these challenges, Chantelle chose the combined Didomi–Addingwell ecosystem, which brings together CMP and server-side tracking.
Didomi: A granular, ethical, and transparent CMP
- Deployment of Didomi across 6 e-commerce sites
- Partner-based consent management, allowing users to know exactly with whom their data is shared
- Multilingual IAB TCF-compliant banners, adapted to Chantelle’s design
- Centralized documentation: cookies, partners, durations, DPAs…
- Complete transparency: Didomi clearly displays all partners, an important element for a brand concerned with protection and ethics
Addingwell: A managed, sovereign, and high-performance server-side solution
- Full migration to server-side tracking: GA4, Google Ads, Meta CAPI, TikTok Events API and affiliates
- GTM proxification to bypass ad blockers
- Dedicated EU and US environments
- Server-side hashing of data for improved ad matching rates and secure transmission
- Fully managed infrastructure, with no internal DevOps workload
Results
The combination of Didomi + Addingwell enabled Chantelle to achieve significant, visible, and lasting gains:
Thanks to centralised documentation in Didomi and more granular, ethical consent management, Chantelle now operates a data ecosystem that is reliable, transparent, and aligned with its users’ expectations, an essential requirement for a lingerie brand where trust is paramount.
Conclusion
In a strict and technically demanding regulatory environment, Chantelle managed to turn constraints into a true competitive advantage. Thanks to Didomi’s CMP and Addingwell’s server-side solution, the company now benefits from reliable, sovereign, and easily scalable data collection capable of handling high volumes while ensuring perfect compliance. The collected data is richer, better leveraged, and fuels advertising platforms more accurately, improving overall marketing performance.
This case demonstrates that a modern data strategy relies above all on trust, transparency, and data quality. For an international brand like Chantelle, where every consent point and every collected signal matters, the Didomi + Addingwell alliance is a decisive lever to support performance, compliance, and customer trust."
