Sarah found success as an entrepreneur by employing a relationship marketing strategy. The goal of this strategy is to:

work closely with existing customers to better satisfy their wants and needs.

Explanation:

Relationship marketing is simply the development, growth, and sustaining of long-term, cost-effective relationships with individual customers, suppliers, employees, and other partners for mutual benefit of parties involved. It emphasize is placed more in retaining or sustaining customers because new customers are more expensive compared to existing customers and can help an organisation have long-term, cost-effective links with individual customers for benefits between both sides.
