Isn't there a law against sending Spam?

The federal anti-spam law went into effect on January 1st, 2004 and preempts all state laws. While this new law will not stop spam, it does make most spam illegal and ultimately less attractive to spammers. The law is specific about requirements to send commercial email and empowers the federal government to enforce the law. The penalties can include a fine and/or imprisonment for up to 5 years.
