Unified commerce and omnichannel personalization

Unified commerce and omnichannel personalization have become essential for international retailers that want to grow across markets without fragmenting the customer experience. As brands expand into new countries, channels and customer moments, the challenge is rarely just about launching a better website or adding another marketing tool. The real challenge is connecting commerce, customer data, marketing execution, experimentation and local market needs into one operating model that can scale.

For many retailers, international growth exposes the limits of disconnected systems. Commerce platforms may vary by market. Marketing teams may work from incomplete customer data. Offers and messaging may be localized, but not coordinated. Testing may happen inconsistently, or not at all. The result is a business that struggles to turn traffic into conversion, marketing spend into efficiency and customer insight into relevance.

At its core, unified commerce brings together the platforms, processes and teams required to serve customers consistently across touchpoints. That means giving shoppers a smoother path from discovery to purchase while enabling retail teams to act on customer signals more intelligently. It also means designing for the reality of international retail: different countries, different customer expectations and different commercial priorities, all managed within a scalable framework.

One leading British retailer offers a clear example of what this can look like in practice. As it sought to grow its international eCommerce business across more than 50 countries, the business needed a stronger digital foundation to support ambitious expansion. Its existing site made it difficult to keep pace with rising traffic and changing expectations across markets. The response was not limited to a front-end refresh. The retailer’s flagship international eCommerce experience was rebuilt on Salesforce Commerce Cloud, supported by Salesforce Marketing Cloud and Einstein to improve customer segmentation, personalization and marketing effectiveness.

That combination mattered because it connected several capabilities that too often remain separate. Commerce became more scalable. Customer understanding became more actionable. Marketers gained the ability to personalize messaging and offers by country and by individual customer across touchpoints. And the business adopted a test-and-learn approach that allowed teams to validate ideas through controlled A/B testing before release. The outcome was a more personalized omnichannel experience, reduced subscriber drop-outs, increased cross-selling, higher online conversion rates and £30 million in additional revenue from continual website optimization in the last year reported.

The lesson is bigger than any one program. Retailers looking to scale personalization internationally need a repeatable model built on five connected moves.

First, modernize the commerce core. International growth is hard to sustain when the commerce layer cannot scale with traffic, content, product complexity and evolving customer expectations. A cloud-based commerce foundation gives retailers the flexibility to improve performance, support expansion and move faster without relying on large, infrequent releases.

Second, unify customer insight. Personalization only works when customer data can be translated into meaningful segments and decisions. Retailers need a clearer picture of behaviors, preferences and purchase patterns across channels. With stronger segmentation, marketing teams can move beyond broad campaigns and create more relevant messages, offers and journeys. This is especially important in international retail, where relevance often depends on balancing global consistency with local nuance.

Third, activate personalization across touchpoints. Omnichannel personalization is not a single campaign capability. It is the ability to deliver connected engagement across digital properties and moments, so the experience feels coherent rather than channel-specific. When commerce and marketing platforms work together, retailers can create journeys that reflect what customers browse, buy and respond to, while still giving country teams the flexibility to tailor execution for their markets.

Fourth, localize without rebuilding everything market by market. International retailers do not need a completely separate digital stack for each geography. They need a shared foundation that enables local adaptation. The right model allows central teams to establish common platforms, governance and best practices, while empowering market teams to personalize messaging, offers and experiences based on country-level needs.

Fifth, embed experimentation into the operating model. Personalization at scale is never finished. Customer expectations evolve, market conditions change and even small experience improvements can have outsized commercial impact. Retailers need agile delivery, continual incremental improvement and disciplined testing to prove value before broad rollout. Controlled experimentation also helps protect performance, including core web vitals, while making optimization an ongoing business capability rather than a one-time initiative.

This is where unified commerce becomes more than a technology agenda. It becomes a transformation in how retail organizations work. Across retail, the businesses making the biggest gains are not simply launching new platforms. They are consolidating fragmented initiatives, breaking down silos and shifting toward more agile, evidence-based delivery models. In that environment, teams can release enhancements faster, learn from customer behavior continuously and adapt without disrupting the business.

For international retailers, this matters because scale can easily become the enemy of relevance. A global footprint creates complexity, but it also creates opportunity. With the right foundation, a retailer can use scale to improve—not dilute—the customer experience. Shared platforms can accelerate rollout. Connected data can sharpen segmentation. Local market teams can personalize with more precision. Testing can make decisions more confident. And the business can create a more resilient path to growth.

The most effective programs also include enablement, not just implementation. New platforms only create long-term value when internal teams know how to use them well. Training, governance and best practices help ensure that capabilities such as segmentation, campaign activation and experimentation continue to mature after launch.

Retailers do not have to choose between global consistency and local relevance. They can design for both. A unified commerce approach makes it possible to create a common digital and data backbone while giving markets the tools to serve customers in ways that feel personal, timely and context-aware.

That is the next frontier for international retail: not simply being present in more markets, but becoming more relevant in each one. Unified commerce and omnichannel personalization give retailers a way to do exactly that—connecting platform modernization, customer insight, localized engagement and continuous optimization into a repeatable model for growth.
