The simple answer is because it works.

Direct Mail is still the most cost effective way to reach potential and existing customers on a personal one-to-one level.

In the past ten years the volume of direct mail in the UK has increased by over 100%.  The increase could be due to the advantages that targeted direct mail gives you over other forms of advertising and the media, for example you are able to target nearly every household and business address in the UK, this gives you access to over 26 million UK addresses.

When a customer receives personalised direct mail they on average spend about 9 minutes reading it, this give you the opportunity to ask the customer direct questions on a personal level, and by supplying a means of response you can get direct answers - a few of the ways of getting a direct answer can be direct contact numbers, reply cards or a return envelope enclosed with or printed on your direct mail.
