The Mailing Preference Service (MPS) is a data file of consumers who have registered their wish not to receive unsolicited advertising material by mail. The MPS is a non profit service managed by the Governance Division of the Direct Marketing Association.
No, there is no requirement to screen customer listings against the MPS.
The consumer can complain to the MPS, who will then write to you for an explanation. If it appears that the complaint is a valid one it will be passed on to the Advertising Standards Authority.
