Which of the following items must be included in an email according to the CAN-SPAM Act?

The CAN-SPAM Act was enacted to regulate commercial email and establish rules for sending such messages. One of the key provisions of this law is the requirement to include a clear and easy method for recipients to opt-out of receiving future emails. This means that every commercial email must provide an option for recipients to unsubscribe from future communications, allowing them to control the correspondence they receive.

This requirement helps protect consumers from unsolicited emails and ensures that they can limit the amount of unwanted communication they receive, thereby establishing a standard for responsible email marketing practices. While the other options may be useful in certain marketing contexts, they do not align with the mandatory provisions set forth in the CAN-SPAM Act.
