True. The twofold goal of marketing is indeed to attract new customers by promising value and to keep and grow current customers by delivering satisfaction. Marketing aims to create value for customers by offering products or services that meet their needs, solve their problems, or fulfill their desires. By communicating and delivering this value proposition effectively, businesses can attract new customers and differentiate themselves in the marketplace. Additionally, by ensuring that current customers are satisfied with their experiences and building long-term relationships with them, companies can retain customers, encourage repeat purchases, and foster customer loyalty. Ultimately, the combination of attracting new customers through value promise and retaining existing customers through satisfaction delivery contributes to the overall success and growth of a business.
