Unsolicited electronic mail without either return email address or toll-free number prohibited
Businesses in Missouri cannot send people unsolicited emails advertising things for sale, rent, or lease unless the email includes a toll-free phone number or a working return email address so the person can ask to stop getting those emails. It is also against the law to help someone send these kinds of spam emails if a person knows the sender is breaking the rules. Phone and internet companies that simply carry the emails through their networks are not considered to be helping in a way that breaks this law.
