The goal of this paper is to demonstrate the importance of electronic communication in today's business environment. Effective communication is the foundation for the development of an internal organization, but it is also a key factor for its existence in an uncertain environment. Communication is thus an important factor both in the behavior of managers and in the functioning of the entire organizational system. Today's organizations communicate with their employees, clients, and partners in different ways, depending on the nature of the message itself, the goals they want to achieve and the strengths (and weaknesses) of the available media: phones, voice messages, faxes and the like. Electronic communication introduces a new channel that changes the way of interaction within companies. Technology makes it easier to connect with co-workers, as well as getting the information needed and helps companies save money on expensive business travel without losing face-to-face communication. There are numerous e-communication tools, each with its own advantages and disadvantages, so the organization should choose the one that best suits its needs. It should be borne in mind that technology is only a tool, a means to accomplish a specific task. It serves as an addition to interpersonal communication rather than a substitute. Managers need to show their employees the means of productive use of information tools because the speed and simplicity of these tools are also their biggest drawbacks. As an example, Microsoft Canada is mentioned as a company which, through the use of the social network Yammer for its internal communications, has improved its place on the market.
