You can send a test message to test subscriber to have the real working link.
you’re displaying that message because you’re testing the newsletter, and therefore it’s only a preview. Please set up a test subcriber (which can of course be yourself) and perform a real sending test. In this way, you’ll be able to test unsubscribe links properly.
