This study investigates the influence of electronic marketing strategies on tourist behavior and attitudes, while examining their contribution to tourism development in Iraq. Employing quantitative methodology, primary data were collected from 384 visitors to religious tourism sites in Karbala Province through structured questionnaire administration. The investigation examines relationships between electronic marketing dimensions, including electronic services, promotion, and payment systems, alongside tourist attitudinal factors and tourism development indicators. Findings demonstrate statistically significant positive correlations between the implementation of electronic marketing and tourist attitudes, electronic marketing strategies and tourism development outcomes, and tourist attitudes and tourism development. Results indicate electronic marketing represents a fundamental catalyst for tourism sector advancement through enhanced destination visibility and improved service delivery mechanisms. Despite Iraq’s substantial religious and archaeological heritage providing significant tourism potential, the sector experiences challenges, including inadequate infrastructure, limited digital marketing adoption, and political instability. The study concludes that systematic electronic marketing campaign organisation alongside comprehensive internet-based tourism marketing restructuring represents essential prerequisites for sustainable tourism development, requiring strategic integration of technological capabilities with infrastructure enhancement initiatives. This research contributes empirical evidence of electronic marketing effectiveness in developing country contexts whilst offering practical recommendations for tourism practitioners and policymakers seeking to enhance destination competitiveness through digital marketing strategies.
