ABSTRACT:
Systems and methods of the present invention provide for detecting and mitigating abuse of undeliverable email or “bounced” emails. An administrator may import a list of email addresses for one or more contacts. The opt-in software may determine if each email address in the list of email addresses is opted in to receive an email distribution, and if so, a bounce detection software may determine if each email address is found in a database of known undeliverable or “bounced” email addresses. If so, an abuse-mitigation software may defer importing the list of email addresses and display an alert referring the administrator to an abuse department for review of the account. A message-delivery software may deliver the email distribution, and the bounce detection software may then determine whether undeliverable emails in the email distribution exceed one or more “bounce limit rules,” and if so, the abuse mitigation software may delay delivery of the email distribution and display an alert referring the administrator to the abuse department for review of the account. Otherwise, delivery may continue to completion.
