Why Klaviyo's view of dynamic creative is misleading

Klaviyo credits a sale to email if the customer opened ANY email in the attribution window — even if they bought through a Google ad
Post-purchase flows get credit for repeat purchases that were already inevitable — inflating email ROAS by 2-5x
Welcome series attribution ignores that these customers just signed up and were going to buy regardless
