Is it illegal to send someone an anonymous letter?
Generally legal unless used for harassment, threats, or extortion.
Sending an anonymous letter is a protected form of expression under the First Amendment and is not illegal by default. However, the legality shifts the moment the content contains credible threats of violence, criminal extortion, or persistent harassment intended to cause distress. While the act of concealing one's identity is permissible, using that anonymity to facilitate criminal activity can lead to federal or state charges. In most cases, a simple anonymous message, even if unwelcome, remains a civil matter unless it crosses into stalking or menacing behavior.
