Mediums, apparatus, computer program code, and means may be provided to launch electronic messages via a distributed communication network by an automated back-end application computer server. According to some embodiments, a database import table associated with a set of electronic destination communication addresses may be created. The set of electronic destination communication addresses may be automatically and dynamically split into multivariate segments, including at least: a current message content subset, a first modified message content subset, and a second modified message content subset. Current message content, first modified message content, and second modified message content may then be automatically launched to electronic destination communication addresses as appropriate in accordance with the multivariate segments. A results log may be created based on computer implemented responses to the messages, and indications associated with the results log may be transmitted to generate an interactive user interface display.
