Confirmation emails provide a valuable service to the sender. They let those sending emails know the recipient has received the desire email and whether or not it was read. Confirmation of these two facts are important for many reasons. Email marketing can be extremely effective. However, if messages are not received or read it is the equivalent of a message falling on deaf ears.
Understanding Email Confirmations
Email delivery confirmations are especially useful if a contact’s email address has not been determined to be valid. The easiest way to tell if an email has not been received is to receive a “failed delivery” message. However, if such a message is not received an email may still go unread due to “spam catcher” techniques used by many common email services. Some anti-spam software will send a “false failed delivery notice” so that an email address cannot be validated.
