Political campaigns send many variations of each email to supporters. We’ve been collecting emails from political campaigns and tracking the variations. You can be a part of this project by forwarding political emails you get to email@example.com.
ProPublica has been collecting political emails for a project we call the Message Machine, with the help of more than 600 readers who have shared demographic information with us and who have so far forwarded us more than 30,000 political emails. The Message Machine identifies and classifies many different emails as different variations of a single email blast, to highlight and analyze the ways in which campaigns use their sizable databases to customize their messages based on what they know about each recipient.
We’ve been publishing our collection for a few months, and today we are publishing the latest results of our analysis. The Machine uses techniques from Natural Language Processing and Machine Learning to analyze every email our readers forward to it.
