My natural question is how is it going to be administered technically and how can it be abused? Because as far as I understand this is a first in such a broad "exception", not banks or health institutuions have such an exception with Gmail. Is it going to be based on SPF? DKIM? Are they gonna whitelist special IPs? What if a politician uses mailchimp? Is it going to be from .gov domains? Email delivery is famously hard to such an exception may lead to some abuse. Of course Google has a lot of engineering capacity but I can imagine a situation where a politician is offered a deal by some newsletter agency to give up access to email get-out-of-jail-free card given by google for a donation to their campaign by said agency.
