The MPS is a free service which enables consumers to register their wish not to receive unsolicited direct mail. The MPS is fully supported by both the Royal Mail and the ICO.
Although registering with the MPS will stop most types of unsolicited addressed mail, it will not stop mail from organisations with which consumers have done business in the past.
If you continue to receive unsolicited mail, despite registering, you’re able to complain to the MPS. In cases when the mailing breaches the Ad Codes, the complaint is referred to the ASA for appropriate further action.
