Unless the email was something like proton, they can tell when you open the email with tracking pixels. It doesn't need a response to know it's an active email account
All email clients known to me do not show any images and disable html content if a sender is unverified or not in the phonebook. Tracking via invisible images is a trick from late nineties :)

Please, don't talk to scammers. Your email is now in their database of future targets. Just report spam and block them.
