The AI can send the outreach messages, and then AI can respond. Then we can all go and retire on a beach while the AI's just bounce off of each ad infinitium.

Unfortunately, there aren't enough beaches to go around, so we will still have to pick winners and losers

> we will still have to pick winners and losers

Why would we do that? Surely there is an AI model that can do it for us.

One small piece of nuance here is that a lot of the times they're not selling your email address, they're hashing it and using it as an identifier for targeting on other sites (so that two sites that both have your email address can coordinate to sell you ads, but sites that don't already have your email address don't learn anything new).

Except it's also trivial to buy or produce tables of pre-hashed emails, so this cloak of "oh we don't know who you are, it's a hash!" is usually just lipservice.

They're not literally passing around the hash. Holders of hash(email) browser cookie associations are heavily incentivized for both regulatory and also competitive reasons to not blast that information around the internet -- or even to let direct partners A & B identify overlaps without their being in the middle.

When passing identifiers, there's generally some combination of lookup tables, per-distribution salted hashes, or encryption happening to make reverse mapping as difficult as possible.

(I was in this space up until a few years ago).

> produce tables of pre-hashed emails Wouldn't this require knowledge of the email beforehand?

I think the idea is that you can generate the MD5 hash of all, say 8 letter, @gmail.com addresses trivially and since the email hashes used for targeting don’t have a salt, it’s a one time “expense” to build the reverse lookup table

Is it approximately correct that most sites (beside Google, Microsoft, Meta, etc.) that get your email address are selling it to data-brokers and sharing cookie/browser-signature information so you can be de-anonymized across the web?

it feels to me that to date, selling people's information remains as the only viable large business model of the internet, after ecommerce

Clearbit's product wasn't that good anymore and they had just got the old CEO back as far as I can remember, they've sold it in a good time then. I wonder if it was a good purchase for HubSpot though, but who am I to judge those M&A's :-)

hum? The original CEO is developing https://reflect.app/

Which makes perfect sense, because why would anyone sell their golden goose, if they had any other possible way of monetizing it?

I don't think this is correct. Meta and Google don't sell direct access to your data. They sell advertising targeting you, based on your personal data. I'm pretty sure it's illegal to sell users email address to a data broker under GDPR.

Right. Meta and Google are much less shady about this.

Not really... they're just vertically integrated and have their own ad networks.

Consequently, they're not protecting data because they care about privacy -- they're protecting data because the wider they share the raw data, the less value it (their product) is.

It's economic self-interest, not ethics.

If they didn't have ad networks, they'd sell anything and everything in a heartbeat.
