A method and system for providing rules-based or algorithms based automated response optimization in the email-marketing environment such that recipient responses during the delivery process of an email campaign influence the delivery parameters and/or message elements of the portions of the campaign yet to be mailed. Responses to an email marketing campaign determine its marketing effectiveness and include delivery statistics, undeliverable statistics, opens, link-clicks, replies, opt-outs, and conversion events. Conversion events are recipient actions that are intended results from the marketing campaign and include marketing or service transactions that are completed online (e.g. purchases, registrations, filling out surveys, etc) and/or offline (e.g. brand awareness, store visits etc.). The system monitors emails as they are being received by recipients during delivery and, based on rules established by the marketer or on default rules established by the system using algorithms, tracks designated response statistics and dynamically alters the email elements, such as subject line and/or other content, including clickable links so that messages that produce the most desirable response statistics is sent to a greater percentage of the remaining recipients. Rather than completing the entire emailing operation using the same content throughout, this invention allows for changing the content for emails remaining to be sent so that the more effective content (in terms of stimulating favorable recipient reactions and purchases) is delivered to as many of the recipients as possible. Additionally, the process may be applied between separately mailed campaigns so that the delivery parameters for subsequent campaigns in a “campaign stream” are automatically modified based on the results of the prior campaigns in the stream and on the rules being applied to the stream.
