Database Marketing

I recieve emails constantly (much to my irritation) from companies that I have previously purchased from. This is a classic example of databse marketing at its finest. You make a one tmie purchase and then you recieve emails long after you have made the purchase trying to tempt you into buying something again. These are obviously companies that have adapted the IMC method of marketing and are clearly not content with offering one time sales, and want to try and encourage brand loyalty though their emails.
