What is Custom Platform + Klaviyo Integration?

Koongo connects your custom e-commerce setup to Klaviyo - an email and SMS marketing automation platform that powers dynamic product recommendations across email flows, SMS campaigns, and real-time feeds - by automating product feed delivery and catalog synchronization. Product data is pulled from your store in XML, CSV, or TXT format and structured to Klaviyo's required XML format without manual reformatting. Koongo's Feed Manager is built for non-standard setups. You configure your data source, use the Rules Editor to map product attributes to Klaviyo's required XML fields, and set automated delivery on a schedule. Koongo's support team handles the initial feed configuration for non-standard platforms. With your feed live, Klaviyo's dynamic product recommendations in your email and SMS campaigns always show accurate products and current data from your custom store.
