The guy in the article mentions a few standards that make email far less scammy / phish-y, how does your idea differ from those? Cause I do agree with the OP article, that the standards and tech are fine, it's really a business / cartel style thing stopping perfectly serviceable open standards.

If your recipients are largely captured by the email giants, which is kind of the "held constant" assumption as time goes on, it's really a chicken and egg question -- does one focus on a new standard or on changing behaviour of the majority of recipients... Because I also really hate the modern "we sent an email conf" flow where random companies who I know aren't fucking it up get bounced by gmail and I have to wait around for a confirmation email or ask them to re-send... Most people don't think about that human/business aspect and just want the email conf "to just work (in less than 1 min)"
