Customer matching
Subtotal identifies a Klaviyo profile using the email stored on the connection. This is the email your application supplies when it creates a Link token or a connection through the Connections API. You can update it through the Connections API. The email collected from the retailer account is not used to identify the Klaviyo profile. An event is not sent when the connection has no email.
