How to block email tracking on Superhuman

Superhuman includes a built-in read-status control scoped to its own behavior. Mailshade separately provides an opt-in integration for the web client: on mail.superhuman.com, Chrome's declarativeNetRequest cancels browser requests that match its reviewed tracker-pixel endpoint catalog. A local DOM scan detects pixels and supported tracking-link patterns; recognized links offer a direct-or-original choice. The dashboard records detected tracker occurrences by sender. This guide describes that tested browser-side scope.

Adding Mailshade on Superhuman

  2. Open mail.superhuman.com.
  3. Open a controlled test message; browser requests matching reviewed tracker-pixel endpoints are cancelled via DNR.
