Marketing by post or telephone
An individual may have registered with the Mail Preference Service (MPS) to say that they do not want to receive direct marketing material by post. It is good practice to check databases against the MPS and take account of the individual's preference, although this is not a legal requirement. However, screening against the MPS is required under the CAP Code and the DMA Code.
If you are carrying out telephone marketing (including sending SMS), you need to check your database regularly with the Telephone Preference Service (TPS) to ensure that the people (businesses and individuals) you are calling are not registered. This is a legal requirement under the Privacy Regulations.
If a business has told you directly that they do not wish to receive marketing by telephone, you must stop marketing to that business.
You can make marketing calls, or send direct marketing by post, to people on your database unless they have said that they do not want to receive the calls or post.
