What must be displayed in the subject line of an email to comply with the CAN-SPAM Act?

To comply with the CAN-SPAM Act, the subject line of an email must provide an accurate representation of the content within the email. This requirement is critical for transparency and ensuring that recipients can make informed decisions about whether to open the email. A clear and truthful subject line helps prevent misleading practices and fosters trust between the sender and the recipient.

By accurately representing the email's content, senders align with the core principles of the CAN-SPAM Act, which aims to safeguard users from deceptive marketing practices. This promotes a responsible email marketing environment where recipients understand what to expect, thereby enhancing the overall effectiveness of communications.
