The rules before you send
Commercial email in the US must follow the CAN-SPAM Act. Among other things, that means no misleading subject lines or headers, a valid physical postal address, and a clear way to opt out that you honor promptly (FTC compliance guide). Sending too much cold email can also hurt your domain’s reputation, so many senders use a separate domain for outreach rather than their main one.
