The problem with a payment scheme is that spammers (who make money by spamming) will happily pay as a cost of doing business (or negotiate discounts/deals), but Joe User might just look at the cost and say, "you know what, maybe I'll send this as SMS instead of E-mail."

So the end result will be more spam and fewer legit E-mails.

I've wondered if it cost $10 to get through my email box the first two times what they would mean.

Hormozi could charge $1,000 to get into his read box.

We could refund people, add them to a whitelist - and return a 405? payment required by default and things change in interesting ways when the amount is variable.

There are platforms based on this idea: pay to reach a public person’s inbox, often with guaranteed responses (“guaranteed” as in “you get a response or you money back”). For example: https://mypublicinbox.com/en/
