How does Ometria identify visitors from a guest checkout?

If your site requires an email address during checkout, the customer will be saved as a contact in Ometria with an order attributed to the email address they enter. 

Be aware that if the customer has not opted-in for marketing emails, they cannot receive any marketing emails from Ometria.
