For Email, the delivery receipt from the email server is considered as an incoming Email. So, if you are running an Email campaign with Delivery enabled then for each outbound Email there will be 1 incoming Email. For SMS, each notification is considered an incoming SMS and each delivery receipt is also considered as an incoming SMS. If a customer is running an SMS campaign with Delivery and Notification enabled, then for each outbound SMS there will be two incoming SMS.
