Which of the following is a CAN-SPAM requirement for real estate email marketing?

• A. Emails must include an opt-out mechanism, truthful header information, a valid physical address, and no deceptive subject lines; honor opt-outs promptly.
• B. Only send emails during business hours.
• C. Headers can be deceptive as long as the content is accurate.
• D. Emails may be sent to any contact without consent if it's business-related.

Answer: (A)

CAN-SPAM compliance in real estate email marketing means every commercial email must include an easy way to opt out, truthful header information, a valid physical postal address, and a subject line that isn’t deceptive, with opt-out requests honored promptly. This combination is why the chosen option is correct: it covers all required elements—an unsubscribe mechanism, honest headers, and a real address, plus a promise to honor opt-outs quickly. The other choices miss essential rules: restricting sends to business hours isn’t a CAN-SPAM requirement; deceptive headers aren’t allowed; and sending to contacts without consent isn’t a permissible shortcut under CAN-SPAM.
