The problem is the definition of consent which says: consent that can reasonably be inferred from: (i) the conduct; and (ii) the business and other relationships This is weaker than the notions of opt-in and opt-out being used in Europe and due to come into law this year. If you register on a supermarket's web site for home delivery, that supermarket can send you special offer emails because it might be inferred you are interested in them. The new European legislation requires such emailing to be explicit and selectable at time of registration. Simon.
