Which piece of legislation addresses unwanted email communication?

The Can-Spam Act is the legislation specifically aimed at regulating unwanted email communication. Enacted in 2003, it establishes rules for commercial email, including requirements for sending promotional messages, giving recipients the right to opt-out of future communications, and setting forth penalties for violations. This Act is focused on ensuring that consumers have control over the unsolicited emails they receive, making it essential in the context of managing online marketing and communication practices.

In contrast, the other options focus on entirely different areas. Truth-in-advertising laws are concerned with ensuring that advertising is truthful and not misleading, primarily in traditional media rather than specifically addressing email communication. The Fair Housing Act prohibits discrimination in housing-related activities, primarily dealing with rental and sales transactions. The Real Estate Settlement Procedures Act governs real estate closing processes and disclosures. Each of these acts serves important purposes within their respective areas but does not pertain to unwanted email communication.
