There were 631 respondents of Generation Z (Gen-Z) included in the sample (Mekong Delta, Vietnam). The SPSS and AMOS measurement and structural models were used in this investigation. This study presents on relevant literature to provide a theoretical framework proposing a connection between the quality of an e-logistics provider's service and the satisfaction and loyalty of its youngest customers, Gen-Z. Perceived online safety (POS), capacity of office employees in e-logistic service center (COS), user interface quality (UIQ), and e-logistic quality (ELQ) are all factors included in this research into e-commerce customers' satisfaction with e-logistics service providers. Online customer satisfaction and office staff capacity in an e-logistic service center were shown to be significant predictors of Gen-Z customers' loyalty to online shopping. E-logistics service quality, such as e-logistics quality, user interface quality, perceived security, perceived privacy, and perceived information quality, is assessed using the current literature. This study's findings suggest that the quality of e-logistics services in Vietnam's Mekong Delta has been reorganized to take into account factors such perceived online safety, user interface quality, e-logistic quality and  capacity of office staff in e-logistic service center.
