According to the CAN-SPAM Act, what must be included in an email advertisement after 30 days?

The CAN-SPAM Act mandates that commercial emails must include a valid physical postal address of the sender. This requirement is essential because it ensures transparency and allows recipients to know where the email originates from. Providing a physical address gives recipients the ability to verify the legitimacy of the sender and offers a method for them to contact the sender if needed.

This regulation not only enhances consumer trust but also helps to combat deceptive email practices. While other aspects of the CAN-SPAM Act, such as including a clear and conspicuous notice or options to manage email preferences, are important for compliance, the inclusion of a valid physical postal address serves a fundamental role in establishing accountability in email correspondence.
