However, ISPs may be reluctant to or face difficulties actually enforcing these terms. In the United States, Controlling the Assault of Non Solicited Pornography and Marketing Act of 2. CAN SPAM Act, permits unsolicited commercial email to be sent if it meets certain criteria, including having an accurate subject line, header and sender address, containing clear information for users on how to opt out of future emails and including a valid physical postal address. The act is enforced by the U. S. Federal Trade Commission. Critics of CAN SPAM deride it for pre empting other more restrictive antispam laws and being ineffectual at reducing the amount of spam users receive. Many countries, including Canada, Australia and the European Union, have passed laws that target the act of sending spam. The EU has a set of guidelines member countries can adapt their electronic communications laws from, but most member countries stipulate that either prior explicit consent or an existing transactional relationship is required before a commercial email is sent, and it should be made easy for the recipient to opt out of any further messages. Offenders may receive fines and other penalties.
