The CPM (also sometimes referred to as CPI) advertising campaign model is a technique applied in the case of website banners, text links, e-mail marketing and opt-in e-mail advertising. However, the opt-in e-mail advertising is generally charged on a [[CPA]] (Cost Per Action) basis. The CPM model along with other fixed rate advertising deals are often preferred by webmasters since the payment is done each time the advertisement is viewed so that the probability of getting paid is higher as compared to other advertising models.
