I get AD emails a fair amount on subjects related to WEBSITES which I have visited. My "Junk Mail" filter usually catches those.
This was the first time I received an ad email related to subject matter contained in a personal EMAIL . . . and three of them within minutes of sending my email.
Perhaps just a coincidence. Kind of freaky, though.
I can understand the email/email connection, but I don't see how your visiting a website could result in targeted emails.
How would the senders get your address?
There's got to be something in what you're doing that's making you vulnerable.
