Great idea, but all these posts deserve the same qualifier: this should be considered an experiment / hypothesis, and not a recommendation that every other site / business / experience should apply without question.

There are times when removing email is best, and others where data or business vertical necessitates something different. You still need to verify with your users and do the appropriate testing / analysis / user research.

100% agree. This worked for us, but is likely to vary by business and this is not a silver bullet. I do think though people who register with email and convert tend to be people who would convert already (i.e., there is a bias already). Product managers can test opening up the funnel more by asking for emails later in the funnel.
