What is Client Communication Plan?

A client communication plan establishes how an agency and client will communicate during an engagement. It covers channels (email, Slack, project management tool, phone), frequency (weekly status calls, monthly reviews), response time expectations, escalation paths for urgent issues, and who communicates with whom. Without a communication plan, agencies default to reactive communication—responding to client emails as they arrive, scheduling calls when something goes wrong, and relying on whoever is available to answer questions. This leads to inconsistent service, missed updates, and the feeling that the agency is hard to reach. A strong communication plan typically includes: a weekly status update (written or via call), a monthly performance review, clear response time SLAs (e.g., email within 4 business hours, urgent requests within 1 hour), a single point of contact on each side for day-to-day communication, and an escalation path for issues that need senior attention. The communication plan should be discussed during onboarding and documented in the project management system. Both sides should agree to it—it protects the agency from "always on" expectations and gives the client confidence that they will be kept informed. Common mistakes include over-communicating (daily calls that could be async updates), under-communicating (clients hear nothing between monthly reports), using too many channels (conversations split across email, Slack, text, and comments), and not adjusting the plan when the engagement evolves. Review and adjust the communication cadence at each quarterly business review—what worked during onboarding rarely fits a mature engagement.
