With the change in behaviour from the customers’ side, due to the increased use of digital environments, marketers have seen a value in customer related data. In order to fully benefit from the data, many marketing efforts have been brought back in to the own organisation. This study aims to further explain how the marketing department have been affected by the changing in-house trend and give practical suggestions on how to cope with the challenges. Previous research in the area has been reviewed and a summary has been conducted. The data collection consisted of semi-structured interviews with marketers from various industries. Respondents with insightful information in the modern marketing department was interviewed and the findings later analysed. The analysis was conducted with support of categories established from the findings in the literature review. The study resulted in a confirmation of the in-house trend in modern marketing departments and the challenges facing them. The findings of the study have contributed to previous literature by confirming and adding insights in a field where most research is made by trade organisations. An independent academic study in the field could be seen as an important addition to the existing literature in the area. For marketers in the area, a greater understanding of the problem will help make the marketing efforts more effective. Key findings include the importance in understanding the customer and what is required in order to make best use of the in-house marketing department.
