Internal marketing is one way to make employees and organizations different from others. In order to differentiate themselves from other actors in the financial sector, financial organizations face the need for competitive differentiation through the implementation of internal marketing. In this regard, previous empirical studies confirmed that the financial sector, especially the banking sector, is the most popular service sector in the context of internal marketing research. According to the above, the purpose of this paper was to present internal marketing, its evolution, application, and role in organizations operating in the financial sector. A preliminary analysis of previous empirical studies conducted in the financial sector showed that researchers used different internal marketing dimensions and tested internal marketing outcomes at different levels. In order to determine the dimensions and outcomes of internal marketing in the financial sector, an analysis of previous studies in this field published in the period from 2015 to the present and stored in Google Scholar base was conducted. The analysis in this paper showed that the most common testing of internal marketing outcomes is at the employee-level as well as the testing of internal marketing dimensions such as (internal) communication, training and development, rewards and other types of compensation, and empowerment of employees.
