Shopify and Klaviyo have expanded their partnership with a deeper integration aimed at international commerce and multi-market customer engagement for brands using Shopify Markets.
The updated integration links Shopify’s commerce tools with Klaviyo’s customer data platform to keep product and customer information aligned across regions. The goal is to reduce inconsistencies between local storefronts and downstream marketing and service communications for retailers operating in multiple countries.
Locale data
A key addition is Locale Aware Catalogs, which synchronises market-specific product data from Shopify Markets into Klaviyo. This includes translated product content, regional pricing, currency, and market-specific URLs.
In practice, marketing and customer service teams get a single catalogue structure that still reflects the local settings defined in Shopify Markets. It also reduces the need for separate regional catalogues and manual workarounds that can introduce errors such as incorrect prices, unavailable product recommendations, or links pointing to the wrong country site.
Locale Aware Catalogs works across Klaviyo’s K:Marketing product and K:Service’s Customer Hub, extending localised catalogue data from the storefront into customer communications.
Cross-border messaging
The integration is designed to let retailers display language, currency, and pricing in marketing messages based on Shopify Markets settings. It also supports regional filtering so shoppers see only product recommendations available in their country or market.
Product links can direct customers to the correct local version of a storefront using Shopify Markets URLs. The companies also described a workflow in which a single marketing template adapts to a customer’s location and preferred language.
Within Customer Hub, the same market settings can carry through into customer-facing service experiences, including recently viewed items, order history, and support content.
AI tools
The synchronised catalogue data can also feed Klaviyo’s AI-driven tools, including Smart Translations and Personalised Send Time. Klaviyo said this helps match messages to the language and location associated with a shopper’s market activity.
The update comes as brands place greater emphasis on cross-border sales. The companies cited a forecast that global eCommerce sales will reach USD $6.4 trillion in 2026 as international expansion becomes a more prominent growth strategy for retailers.
Klaviyo also referenced an IDC Business Value Executive Summary, which it said found brands using Klaviyo and Shopify together recorded 73% revenue growth over three years. The announcement did not include details on sample size or methodology.
Retail use case
Reebok Europe, part of GB Brands, shared its perspective on the update and its relevance for regional operations.
“Maintaining a seamless and localized customer experience is critical,” said Marc Le Roux, Chief Executive Officer for Reebok Europe (GB Brands). “Shopify Markets gives us the infrastructure to localize our storefront, and with Klaviyo’s Locale Aware Catalogs, that same accuracy carries through to our marketing and customer engagement.”
Shopify described the deeper integration as part of its broader ecosystem approach, in which partners add native connections to its commerce platform.
“Extending Shopify Markets’ infrastructure into Klaviyo makes it easier for merchants operating across multiple regions and channels to scale internationally,” said Atlee Clark, VP, Partnerships, Shopify. “This is our ecosystem at its best: native integrations that help merchants reach more customers globally, without added complexity.”
Klaviyo also positioned the update as a step toward running global operations from a single strategy while maintaining local presentation in each market.
“Our partnership with Shopify is built on a shared vision to make brands more successful as they scale globally. Shopify enables merchants to sell anywhere and Klaviyo helps make every customer relationship more valuable,” said Andrew Bialecki, Co-Founder and Co-CEO, Klaviyo. “Innovations like Locale Aware Catalogs allow merchants to access Shopify Markets in Klaviyo, helping businesses run one global strategy while delivering experiences that feel truly local in every market. The result is a more accurate, consistent customer experience across borders and reduced operational overhead for global teams.”
Locale Aware Catalogs is available immediately for Shopify Markets merchants using Klaviyo. Klaviyo expects the integration to expand alongside future Shopify Markets developments, with additional commerce data becoming available in its CRM as Shopify updates its international tools.
