Perhaps it takes time to interface and aggregate pricing data from the various quoting systems. I doubt your email address is shared, as part of a marketing agreement, as part of the quoting process.

Now, if you select a quote, then I imagine your email would be shared and a $xx commission would be paid to Google. Curious to review the terms or see the business heuristics.

This is how <all> the insurance aggregators do it. I don't have an answer why, but this is how they all do it.

I understood why they did this 9 years ago, when I first bought auto-insurance online, but it's certainly not a technical requirement it be done this way now. My hunch is there's some kind of regulation/agreement between insurers that quotes not be made available on a website, and emailing the results is a loophole.
