Abstract: A system for breaking down, collecting, and analyzing specific keywords included in sent emails where value is assigned to such keywords, which in turn compares the subject category that is most relevant to that email. From there, the advertisements are pulled from this subject category to include within the particular email. In this manner, the advertisements are tailored to individual sent emails based on the content contained within the email message.

Abstract: A system that bounces misdirected electronic mails for notification and monetization purposes or otherwise submits a series 550-error email, via a computer, back to the original sender. The system also relates to breaking down, collecting, and analyzing specific keywords included in sent emails where value is assigned to such keywords, which in turn compares the subject category that is most relevant to that email. From there, the advertisements are pulled from this subject category to include within the particular email. In this manner, the advertisements are tailored to individual sent emails based on the content contained within the email message.
