A London-based e-company is to launch a service enabling Net users to request direct marketing e-mails. OK-mail - said to be the first opt-in service in Britain - will collect and provide e-mail addresses of consumers who have specifically asked to receive online mailshots. Lionel Thain, one of the co-founders of OK-mail, said; "We are totally anti-spam. We always seek permission from consumers before sending them any information." The service has been designed so that Net users have to give their consent twice - once when they register and once to confirm. This, according to Thain, will ensure that people's names are added to the list without their consent. OK-mail received 1 million in VC backing in March and reckons it will have signed up between two and three million people by the end of the year. To find out more go here.
