Hey @Shikha
Welcome to the Klaviyo Community! Thanks for asking about using language based catalog feeds!
You will need to create a custom catalog feed for each language that you want to send to. The best way is to set up different Custom Catalog Feed for each language is to add a prefix to the product ID/Product identifier to differentiate the different versions of the product and to indicate the language of the product. Once the custom catalogs have been created successfully, you can use the catalog lookup function in your email templates to show specific product information based on language. If you need help creating the custom catalog feeds, please connect with one of our agency partners who can assist you in getting this implemented!
Thank you again for being part of the Klaviyo Community!
