1. Why blockchain? As a tech savvy person you could do this right now with autoresponders and normal whitelists. In the same way, you could just develop a decentralized standard on normal web technology. In your business card qr code example, you'd just be led to a page with a message form where the sender puts their own email which is either whitelisted automatically or there's a payment option included.
2. With or without crypto, the problem remains that, aside from the clever business card idea, you have to whitelist every person you want to be able to email you without paying. And what if you whitelisted a whole company but now someone from that company who you befriended wants to email you from their private account to get coffee or whatever? Or THEIR friend with no company affiliation at all wants to message you for whatever good reason? Solvable but annoying. I think this falls apart once you bring private emails into this. Then again, maybe people will stop using email for private matters at the point where something like this is really necessary.
Cool idea, but:

i found this quite intriguing!
