If you ever once donate to a candidate or sign up for a candidate newsletter, you are forever on some master list and can never get off it. You can unsubscribe from individual candidate lists, but every year when new candidates join, they’ll just put you on those candidate’s lists and you’ll have to unsubscribe all over again. It’s obnoxious as hell and should be illegal. And, I might be interested to hear from a political candidate from time to time, but it’s not like that. They email you up to 5 times a day with annoying click-spammy titles.
