Browsing for an obscure piece of electronics, I ran across a Poshmark listing that had it for considerably cheaper than anywhere else.

I didn't have an account yet, so I signed up with Google SSO and was able to place the order.

About an hour later I got an email as if I was the seller telling me to click this link to verify my account for my funds to be deposited.

Obviously phishing. Upon closer inspection, I had two earlier that were properly filtered to spam that were about 30 minutes after the order.

So the question here is what part of their system is so fundamentally broken that scammers instantly get my email? Does the seller get that upon me making that purchase?

And if that's not the case, then that means somebody has completely compromised their system.
