Database marketing

Database marketing is a way of building relationships with customers so that businesses can offer them the right kind of products and services. Businesses create databases filled with information about their customers. This information could include details like the customer's address, birth date, phone number, past purchases, and interests. The business can then use this information to communicate with customers and tailor their marketing messages to offer the customer products and services that they would be interested in.
