The marketing environment refers to the external and internal factors that influence a company's ability to develop and maintain successful customer relationships. It consists of the microenvironment, which includes stakeholders such as customers, competitors, suppliers, intermediaries, and the company itself, and the macroenvironment, which encompasses broader forces like economic, social, technological, political, legal, and environmental trends. Businesses must continuously monitor and adapt to these dynamic factors to stay competitive, meet consumer needs, and achieve long-term success.
