The Federal Trade Commission published a 30-page Notice of Proposed Rulemaking in the Federal Register on Wednesday, proposing a series of new Can-Spam regulations, reports BtoB Online. The regulations cover, inter alia, the definition of "sender" and what to do when there are multiple senders, shortening the time period to comply with opt-outs to only three business days, "forward to a friend" programs, and the scope of the "transactional and relationship message" exemption from much of Can-Spam requirements. Comments are due to be filed at the Federal Trade Commission by June 27.
