They read it off the page. Meta&rsquo;s automatic advanced matching watches form fields, and when a visitor types into one that looks like an email field, the pixel hashes what it finds and sends it with its next event. The visitor hasn&rsquo;t pressed &ldquo;Sign up&rdquo;. They might never press it.</p> <p>This is hard to see from the site&rsquo;s side. Nothing in the site&rsquo;s own code mentions the email field. The behaviour comes with the pixel, switched on with a checkbox in an ads dashboard.</p>
