What it does mean, though, is the person who sent the email now knows, at the minimum:

1. Someone receives and reads the email sent to this email address.

2. That person is willing to enter data into a form.

This is 2 pieces of information the person didn’t have before, and it can be used in further phishing attempts in a variety of ways.

It doesn’t mean you were fooled, but that’s only half the story.
