Klaviyo notes/limitations

Customers do not need to be subscribed to your newsletter list in order to trigger Checkout Started event in Klaviyo. + While Shopify tracks Abandoned Checkout events, Klaviyo tracks Checkout Started events. This is because Checkout Started necessarily captures an email address that Klaviyo uses for sending abandoned cart emails.
