In our experience, whitelisting really doesn't solve the problem. I often get email from people I don't know about things I want to read about ("hey, I'm a VC who wants to give you money!").

Automagically parsing receipts is certainly cool, and several mail vendors are working on it, including us (Inky).

Guaranteed delivery isn't really possible without controlling both sender and recipient's client; nor is immediate delivery.

You're right about delivery. This is something we are going to work on. Don't think of us as a competitor. We want to create an infrastructure and we need client solutions to work with us ;-)
