After an XML submission, the server returns an XML Response
Document. The response is an assurance of receipt and of sending to the contact, or it reports a non-delivery and the reason.
The response is sent either as a string returned from the HTTP request, or delivered to the status directory of the submitter’s FTP site if the submission is sent by using FTP.
Be aware that the Delivery confirmation option (contact receipt acknowledgment) of the email is set in the interface and is sent to the email address specified in administrative settings. The response identifies the group of automated messages, transaction, number of contacts, error, status, and contact information.
