The best approach for a project manager in this situation is to include the project stakeholders’ needs while planning the project communications strategy. This ensures that all stakeholders are considered and their information needs are met in a structured way, which can prevent the need for them to send individual emails requesting information. According to the PMBOK Guide, the communications management plan is a key component of the overall project management plan and outlines how project communications will be planned, structured, implemented, and monitored for effectiveness. It includes stakeholder communication requirements, information to be communicated, methods or media for communication, time frames, and frequency of communication, which aligns with option B1.
