Prohibited acts

In plain English

This law is about spam emails sent to people in Missouri. Whoever sends a bulk advertising email cannot use a fake name or lie in the subject line. Unsolicited (unwanted) ad emails must start with 'ADV:' in the subject line. If the email has adult or obscene content, it must start with 'ADV:ADLT' instead. If someone tells a sender to stop emailing them — by replying, calling, or contacting the attorney general — the sender cannot keep sending those emails. The attorney general can make extra rules to enforce this law.
