24/7 Media announced today its intention to implement a Closed-Loop-mail subscription process that confirms the validity of new subscriber sign-ups to protect consumer privacy and forestall accidental
or malicious e-mail sign-ups. The new Closed-Loop process, also known as “double opt-in,” requires that an e-mail message be sent to the new subscriber, asking him or her to confirm a new e-mail
subscription under the given e-mail address. The subscriber must affirmatively reply to the confirming e-mail for subscription to begin. 24/7 Media is requiring all new service bureau clients to agree
to implement Closed-Loop and is working with existing service bureau clients to implement Closed Loop over the next few months.
