The Unsolicited Electronic Messages Ordinance ("the UEMO") has fully commenced on 22 December 2007. Now, senders of commercial electronic messages are required:

  1. to provide clear and accurate sender information in the message;
  2. to provide an unsubscribe facility and an unsubscribe facility statement in the message;
  3. to honour unsubscribe requests within ten (10) working days after the request has been sent;
  4. not to send commercial electronic messages to any telephone or fax number registered in the Do-not-call Registers starting from the tenth (10) working day of its registration, unless consent has been given by the registered user of the relevant telephone or fax number;
  5. not to hide the calling line identification information when sending messages from telephone or fax numbers; and
  6. not to send email messages with misleading subject headings.

In addition, the UEMO also prohibits:

  1. the use of unscrupulous techniques to expand the reach of commercial electronic messages; and
  2. fraud and other illicit activities related to the sending of multiple commercial electronic messages.
