Thank you for your question that will allow me to clarify matters. What I said was that given the notion of implicit, tacit consent, there is nothing stopping a company that has an existing business relationship with a customer from sending that customer within the allowable 18-month period an email asking him if he would like to receive additional information over the next few years. Then, the relationship could continue indefinitely or until such time as the consumer or the company decides to end it. This would be part of the express consent provision, to avoid a debate on whether the period of implied consent should be 18 months, two years, five years, eight years or twenty years. I think it's clear that any business can send out an email, once a business relationship has been established, and ask the customer for permission to continue sending emails.
