The adoption of e-marketing among SMEs is still comparatively low, especially in developing nations like Jordan. This research paper aims to investigate the influence of resource availability on the adoption of e-marketing by Jordanian SMEs. 264 Jordanian small and medium-sized enterprises (SMEs) were the subjects of a cross-sectional survey study, selected using stratified sampling followed by simple random sampling. The researcher gathered information on SMEs' availability of resources and adoption of e-marketing in Jordan, the data was analyzed by utilizing SmartPLS (PLS4). The findings of the study demonstrated that Jordanian SMEs' adoption of e-marketing was significantly influenced by the availability of resources. The adoption of e-marketing was also significantly influenced by the size of the SMEs, with larger SMEs adopting e-marketing more readily than smaller SMEs.
