Here is what CAN-SPAM requires, following the updated rules issued by the FTC in May of 2008; this is the "single step" requirement:
ยง 316.5 Prohibition on charging a fee or imposing other requirements on recipients who wish to opt out. Neither a sender nor any person acting on behalf of a sender may require that any recipient pay any fee, provide any information other than the recipient's electronic mail address and opt-out preferences, or take any other steps except sending a reply electronic mail message or visiting a single Internet Web page, in order to: (a) Use a return electronic mail address or other Internet-based mechanism, required by 15 U.S.C. 7704(a)(3), to submit a request not to receive future commercial electronic mail messages from a sender; or (b) Have such a request honored as required by 15 U.S.C. 7704(a)(3)(B) and (a)(4).
