Anti-spam organizations recommend you always report spam to the FTC, which maintains an email spam database that is the reference point for taking action against those who send deceptive or fraudulent email.

If you have a specific complaint about an unsolicited commercial email you received, you can fill out this FTC Consumer Complaint Form. This is also the form they want you to use if your "opt-out" request was not honored.

If you want to report any fraudulent spam or violations of CAN-SPAM, simply forward the offending email directly to uce@ftc.gov. You do not need to fill out a complaint form for this.
