That's a nice find. It's worth skimming the full email for context. He's laying out the draft organizational plain for a modern campaign and it's about what you'd expect. The only interesting part is that it's actually public and, to me, how non-conspiratorial these emails have been. Clearly some people take a different view.
Can't read the email itself, but these excerpts almost seem to imply that they'd be using Google's data in order to construct this? Is this an incorrect read? Or is he just outlining how to build such a system in the abstract?
The latter. He mentions buying data from the standard marketing sources and hosting systems on AWS.
