recipient
The term “recipient”, when used with respect to a commercial electronic mail message, means an authorized user of the electronic mail address to which the message was sent or delivered. If a recipient of a commercial electronic mail message has one or more electronic mail addresses in addition to the address to which the message was sent or delivered, the recipient shall be treated as a separate recipient with respect to each such address. If an electronic mail address is reassigned to a new user, the new user shall not be treated as a recipient of any commercial electronic mail message sent or delivered to that address before it was reassigned.
