Sales email from anonymous website visitor

Question

Twice in the last week, I've gotten a sales email from a saas startup shortly after visiting their public site. One was a YC company and the link was from here.Are they perhaps using a service that offers unique emails for anonymous website visitors, from third party cookies?

There is services like https://salesinfo.io that identify website visitors (company contact info) if they are on a company network usually based on their ip adress (no cookies to my knowledge). But how they got to your email adress and direct contact is interesting. Would you be able to share the site you visited?
