Is there a public git repo that lists all the email campaign providers that are sending these emails and that lists their sending domains, AS numbers and CIDR blocks? Another question just started rattling around in my head. How do the senders determine the valid and verified email addresses of US citizens? Are they buying lists or are people knowingly opting into this system? Or are they just pulling in email addresses from disparate government databases? Are they using data in ID.me? [1] Also, is this assured to be a bi-directional communication or is this just a broadcast to the citizens? If I reply will it be to a "noreply@" address? Will these politicians enter into a forum and be open to unscripted and uncensored real time conversations? If it's a broadcast then could it not just be a Twitter feed that optionally links to a vlog post? If this must be targeted to individuals, then is this by chance a reaction to incidents like the Facebook-Cambridge Analytica data scandal? [2] My personal preference would be that politicians just have their own Youtube/Bitchute/Rumble/other channels and let their messages grow organically and let people subscribe to them. If legal to do so they could even monetize the channel to pay for their campaigns. The more popular they are with their constituents, the more ad revenue they make.
