Why are the customers in my Shopify list not in any of my Klaviyo lists?
Klaviyo will sync over all of your current contacts from Shopify and create a profile for them. But, they will not be added to a list in Klaviyo. If you wish to have your contacts in a Klaviyo list, we recommend exporting the list from Shopify and importing them into Klaviyo. Head to this article on Create and Add Contacts to a New List for more information.
