Commitment Form Advertising (CFA) is an advertising strategy that encourages customers to make a commitment to purchase a product or service. It is typically used in direct response marketing, and requires customers to fill out a form with their contact information and payment details. This form is then used to create a binding agreement between the company and the customer that they will purchase the product or service. CFA is a powerful way to build relationships with customers and increase customer loyalty. There are two main types of CFA: fixed-term commitment and open-ended commitment. Fixed-term commitment requires customers to commit to a specific length of time, such as 6 months or 12 months. Open-ended commitment allows customers to purchase the product or service for an indefinite period of time, with the option to cancel at any time. Both types of CFA require customers to provide their contact information and payment details. Overall, Commitment Form Advertising is an effective way to increase customer loyalty and build relationships with customers. It encourages customers to make a commitment to purchase a product or service, and provides companies with a binding agreement.
