In a fast-paced world where communication needs to be efficient and agile, various platforms have emerged to support business leaders and their teams. According to the 2025 Internal Communication Trends Survey conducted by Ação Integrada and Aberje, WhatsApp is among the channels expected to see the most growth and implementation by companies this year.

As an ally in internal communication, WhatsApp facilitates exchanges and strengthens relationships among employees. The study also highlights that the platform is one of the most effective communication tools for immediate managers, ranking second (28%)—trailing only email (74%).

This trend underscores the need for companies to develop more concise and dynamic materials to ensure messages are delivered quickly, efficiently, and clearly. Given employees’ busy schedules and the demands they face, the preference for practical and direct content is evident. WhatsApp’s familiar interface and interactive features help drive engagement organically.

The survey also found that 19% of companies consider formal internal channels—such as intranet, email, corporate TV, newsletters, and even corporate WhatsApp—to be the most effective. As a result, integrating these communication tools allows for greater fluidity and clarity in internal messaging.
