The high rate of digitalization of education services has significantly changed the way education agencies recruit, communicate with, and provide services to potential students. In this respect, data-driven online marketing has become one of the strategic tools that provide individualized educational services, which address the needs of various learner profiles and expectations. The current research paper is a critique of how education agencies have implemented the use of data analytics and digital marketing technologies to shape personalisation strategies and improve student engagement. The qualitative research design was embraced, where a semi-structured interview was conducted with the professionals in education agencies to investigate their experiences, perceptions, and practices concerning data-driven marketing. The results have shown that the use of data-informed decision-making can allow the agencies to optimize the audience segmentation, communication strategy, and service delivery during the student recruitment lifecycle. However, the issues of data integration, ethical issues, and organisational capacity still encroach on the largest scale of personalized approaches. The research paper is also relevant to the already existing literature in both providing empirical information regarding the role of data-driven digital marketing in education agencies and in pointing out its effects on the construction of personalized education services in the increasingly competitive global education market.
