Is if.inboxfirst.com Safe?

"Inbox First" is a bulk mailer intended for use by "conservatives", mainly U.S. Republicans. It has no malware, but the excellence of its ToS is tarnished by the "cancel culture" lament in its About page; my dog no doubt shares this sentiment about my refusal to sniff its droppings. Unfortunately its customer of the moment, Nikki Haley, like many of her addled "Q-anon", "MAGA", 2020 election denying ilk, abuses said ToS, as they have done since minions of the would-be fascist dictator POTUS45 began spamming my email address.

I'm being spammed by a far-right group I'd never even bloody heard of. They're not even on the same side of the planet as me. Well, two far-right groups, to be honest. One of them is some clueless gibberer calling himself Paul Rand, or Rand Paul. Hard to tell. He is, however, a complete jerk as well as monumentally stupid. The other claims to be a radio station. Same adjectives apply. I suspect one of them somehow got hold of my email (bought it off a dictionary attacker?) and sold it to the other. Privacy laws? What privacy laws? So no: I don't trust this lot. They host extremist spammers.
