When I upload a new list to Klaviyo using a Shopify Customer csv file, there might be multiple profiles that already existing in Klaviyo. Some of those profiles may have unsubscribed from previous email campaigns. When I upload the new list the suppressed profiles on Klaviyo get affected and are shown as “subscribed” again.
How to I prevent this from happening and ensure that any profiles that have unsubscribed from email campaigns remain this way?
