• An email recipient cannot be required to pay a fee, provide information other than his or her email address and opt-out preferences, or take any steps other than sending a reply email message or visiting a single Web page to opt out of receiving future email from a sender.

• The definition of “sender” was modified to make it easier to determine which of multiple parties advertising in a single e-mail message is responsible for complying with the Act’s opt-out requirements.

• A “sender” of commercial e-mail can include an accurately-registered post office box or private mailbox established under U.S. Postal Service regulations to satisfy the Act’s requirement that a commercial e-mail display a “valid physical postal address.”

• A definition of the term “person” was added to clarify that CAN-SPAM’s obligations are not limited to natural persons.
