'KS-SQI' is a service quality standard evaluation model jointly developed by the Korean Standards Association (KSA) and the Seoul National University Business Research Institute. It serves as a customer satisfaction index that indicates the quality level of the domestic service industry. In this year's evaluation, 11st Street received high scores in areas such as service expertise, service outcome quality, and social value.

11st Street is providing a differentiated shopping experience by offering services optimized to meet changing customer needs in the evolving e-commerce environment and consumer trends. A representative example is the free membership program, '11st Street Plus.' This service allows customers to enjoy membership benefits without any additional sign-up fees, and enables up to five people to form a 'family' group; when they achieve a purchase goal together, '11Pay Points' are awarded.

The company is also focusing on strengthening its competitiveness in the 'Mart' and 'Fashion·Beauty' categories. In May, 11st Street launched the integrated shopping specialty zone 'Mart Plus,' where customers can browse and purchase products from SSG.com's 'Emart Mall,' 11st Street's 'Fresh Table' (a vertical specializing in fresh food), and 'Shooting Delivery' (a fast delivery service for daily necessities) all in one place. Additionally, the company opened the 'Fashion·Beauty Specialty Zone,' which brings together more than 500 popular fashion and beauty brands, further enhancing the shopping experience for customers.

The company is also strengthening its delivery capabilities. 'Shooting Delivery,' 11st Street's fast delivery service, began offering 'same-day weekend delivery service' in February, and since May has expanded weekend delivery coverage from the Seoul metropolitan area to nationwide, now operating a 'seven days a week delivery' system. In addition, support for marketplace sellers continues to be expanded.

Hong Changyoung, Head of Customer-Centric Management at 11st Street, stated, "This achievement is the result of our focus on quickly responding to changing customer needs and providing optimal services," adding, "We will continue to enhance service quality, offer even more differentiated shopping value, and further increase customer satisfaction."
