If you can't stand junk mail any more, you will soon be able to tell Hongkong Post where to stick it. Starting from September 1, residents will be able to exclude certain unaddressed circulars, by putting a sticker on their letter box. The scheme, introduced by Hongkong Post yesterday, applies to the mounting piles of Hongkong Post Circular Service mail, which has a specific Hongkong Post mark printed on its top-right corner instead of the name and address of a recipient. The circular service, which according to the postmaster general sent out more than 119 million circulars in 2009, offers discounts to companies that send more than 2,000 promotional messages to potential customer segments, without the need for address labelling. The service can save up to 36 per cent on standard postage rates and eliminate the cost of packaging and labelling, according to Hongkong Post. But Hongkong Post carried out research and consultations from last October to May this year, in response to an investigation report by the Ombudsman on a complaint case that an option not to receive the unsolicited mail was not effective. The Ombudsman concluded that the circular service was 'an abuse of the postal service', which created unwanted nuisance and annoyance. The Ombudsman's report says that the Mandatory Opt-out Scheme introduced by Hongkong Post in 2007 is unrealistic, as it requires recipients to instruct each and every sender to stop sending circular mail to them. There is no sanction against non-compliance. Hongkong Post completed a review of the opt-out scheme, to look for a simpler and more direct way to block unwanted circulars. During the review process, Hongkong Post referred to the practices of the postal services of 50 countries or regions: 28 distribute unaddressed mail, and 11 have selected the sticker scheme. Clement Cheung Wan-ching, postmaster general, said that countries including the United States, Canada and France had been using the scheme for more than 10 years, and it had been welcomed among their communities. Hongkong Post also conducted online interviews via Facebook, telephone surveys and surveys distributed to households. 'Of the 2,000 interviewed, over 70 per cent of the respondents said they welcomed the new scheme, and 33 per cent said they would use the stickers,' Cheung said. 'In 1998, we sent out 40 million circulars, and in 2009 more than 119 million circulars were distributed, and we see an increasing demand for the service.' Cheung said the new scheme would exempt circulars from government departments, legislative and district councillors, election candidates and some charitable bodies. These organisations accounted for 6.5 per cent of the total number of circulars, the rest being mostly from small and medium enterprises.
