It's possible to redirect a user when he click a link that expire (unsubscribe, list delete, )etc instead to see Error 404!
The requested page does not exist.

Yes there is, mailwizz >= 1.3.5.8 has support for this.
Edit your list (i.e: /customer/index.php/lists/xxxyyyzzz/update ) and fill in the "Subscriber not found redirect" field.
