This originally appeared on the Annexe, chronicling my adventures unsubscribing from email newsletters. The only acceptable outcome from clicking unsubscribe in an email footer is immediately being unsubscribed!

Email:

Box: Keep all your best ideas in one place, wherever you need them: on mobile, web — and now — your desktop. Learn more.

Footer:

About Box | Unsubscribe | Privacy Policy

Result:

Firefox can’t establish a connection to the server at em.box.com.

FAIL.
