If the message recipient submits a request to opt out of receiving future message from a sender, all of the following apply:
- The opt out must become effective within 10 business days. After this time, the sender (or anyone on its behalf) may not send further commercial e-mail messages falling within the scope of the opt-out request to that recipient, unless the recipient subsequently requests to receive (opts in) these messages.
- The opt out never expires.
- The sender (and any other person that knows the recipient has opted out of further commercial messages) cannot sell, exchange or otherwise transfer the recipient’s e-mail address except as required by law unless that recipient has explicitly opted in to permitting the sale, exchange or transfer.
