Unlimitail launches “Social Retail” and shopper data takes over social media

For the first time in Europe, a retailer's transactional data is natively connected to the heart of social networks . By merging the ultra-granularity of Unlimitail's proprietary data with the coverage and algorithmic power of social platforms, “Social Retail” aims to transform Social Media into an unprecedented lever for transactional growth.

‍

Paris, April 2026 - Unlimitail, the European leader in Retail Media, announces a strategic breakthrough: the native injection of shopper data, starting with Carrefour and its 14 million card-holding households in France, directly into the engine of social networks.

‍

This proprietary solution, operational as of April 2026, natively integrates Carrefour data into the core of major social platforms, with a roadmap designed to gradually extend coverage to the entire social media ecosystem.

Direct Integration: the innovation removing barriers

‍

Social Retail Media has reached a new level of maturity today. By bypassing third-party intermediaries in favor of a direct connection, Unlimitail is removing traditional barriers to offsite activation to finally reconcile social exposure with transactional reality.

‍

This native unification allows for a massive and fluid injection of shopper data into platforms. It guarantees a matching rate (the share of the initial audience identified and activable on the destination channel) and measurement precision previously unattainable, offering brands total transparency regarding the real impact of their campaigns.

An Unprecedented Performance Loop: From Intelligent Targeting to Sales-Driven Management

‍

Beyond technical innovation, Social Retail redefines media intelligence by enriching traditional indicators (views, clicks) with the reality of the purchase act. Advertisers are no longer limited to managing by CPM (cost per thousand) or CPC (cost per click); they can now optimize campaigns via concrete business indicators such as incremental sales, recruitment, profitability (Return On Ad Spend), or brand KPIs (memorability, preference, cross-sell) directly correlated to sales.

‍

This new efficiency rests on three major levers: targeting, optimization, and measurement. The synergy between transactional data and Artificial Intelligence identifies and addresses profiles with the highest purchase probability to build the best audiences. 

‍

Fed by transactional flows from both in-store and online at an unprecedented level of granularity, the system learns continuously. It allows for delivery adjustments to serve the most effective creative assets and formats to the right profiles during the campaign itself. 

‍

Finally, advertisers have access to measurement that directly links advertising exposure to the final sale. For advertisers, this clarity addresses complex business challenges: supporting innovations and product launches, boosting core range sales, and navigating a brand portfolio, all via strategic media plans fully measured by objective.

2026: Strategic Acceleration of Offsite

‍

This strategic acceleration is part of Unlimitail's evolutionary momentum, alongside solutions such as In-store attribution or the Creative Studio. Unlimitail thus reaffirms its commitment to bringing more simplicity and efficiency to the market through constant innovation.

‍

Available starting April in France, the product will be deployed in Spain and Brazil in the third trimester, with a progressive extension to other social networks and partner retailers within the network.

Alexis Marcombe, CEO of Unlimitail: “Social networks know how to reach everyone. We know what everyone buys. Social Retail brings these two forces together to offer brands and agencies a unique solution for the first time: performance media at scale, capable of targeting, optimizing, and measuring on a single indicator: the transaction.”
