Internal Communication Plan: Template, Example and Step-by-Step Guide

What is an internal communication plan?

An internal communication plan is a documented approach that sets out what an organisation needs to communicate to employees, why, to whom, through which channels and when. It connects business priorities to specific messages and gives communicators a shared reference for timing, ownership and measurement, rather than reacting to requests as they arrive.

An internal communications plan can cover the whole organisation for a year, a single department, or one initiative such as a system rollout or restructure. The structure is the same in each case. What changes is the scope.

Why do you need an internal communication plan?

Without a plan, internal communication tends to become reactive: messages compete for attention, important updates arrive through the wrong channel, and nobody can show what was read. A plan sets priorities, reduces overload and makes it possible to show that critical messages reached the right employees, which matters most in regulated industries.

There is a clear case for improvement. Gallup's State of the Global Workplace 2025 report found that global employee engagement fell to 21% in 2024. Engagement has many causes, but clear and consistent communication is one that internal communicators can influence directly.

What should an internal communication plan include?

An internal communication plan should include clear objectives linked to business goals, defined audiences, key messages, the channels for each audience, a timeline or calendar, named owners and approvers, and the measures you will use to judge success. Together these turn a list of announcements into a plan you can run and review.

1. Objectives

What the communication needs to achieve, written as an outcome rather than an activity. "90% of staff complete the new security training by 31 March" is an objective. "Send a security email" is not.

2. Audiences

The groups who need to hear each message, segmented by department, location, role or working pattern. Office-based, remote and frontline employees rarely need the same channel.

3. Key messages

Three or four core points per objective, written in plain language, so every channel and spokesperson says the same thing.

4. Channels

Where each message will appear, chosen by urgency and audience. Routine news, mandatory updates and urgent alerts each need a different approach.

5. Timeline

When each message goes out, including any sequence such as an announcement, a reminder and a deadline notice.

6. Owners and approvals

Who writes, who approves and who sends each item. Clear ownership prevents delays and conflicting messages.

7. Measures

How you will judge whether the plan worked: reach, read and acknowledgement rates, feedback, and the business outcome in the objective.

How to create an internal communication plan in seven steps

The steps below take you from a blank page to a plan you can run. For an organisation-wide plan, allow time for steps 1 and 2; for a single initiative, they can often be completed in a single working session.

1. Review what you have. List current channels, recent messages and any data on how they performed. Note where employees say they miss information.
2. Agree objectives with leadership. Tie each objective to a business priority and agree how success will be measured.
3. Map your audiences. Segment employees by how and where they work, and note which channels each group actually sees.
4. Write the key messages. Draft the core points for each objective and have them approved once, so they can be reused.
5. Choose channels and build the calendar. Assign each message to channels and dates, avoiding clusters where several announcements land on the same day.
6. Assign owners and approvers. Name a person for each item and agree turnaround times for approval.
7. Measure and review. Record a baseline, track results as messages go out, and review the plan at least quarterly.

Internal communication plan template

Use the structure below as your internal communication plan template. Each row is one message or activity. Copy it into a spreadsheet or document and add rows as the plan grows.

Internal communication plan example

The example below shows a plan for a single initiative: moving the organisation to a new expenses system. The same structure scales to an annual plan.

• Objective: all employees submit expenses through the new system from 1 June, with at least 95% of June claims submitted without needing support.
• Audiences: all employees who claim expenses, line managers who approve claims, and the finance team.
• Key messages: the old system closes on 31 May; the new system is faster to use on mobile; guidance and support are available.
• Channels: a leadership announcement in the monthly newsletter, a desktop alert on launch day, a ticker reminder in the final week before the switch, and a short guide on the intranet.
• Timeline: announcement six weeks before, manager briefing four weeks before, reminders two weeks and two days before, launch-day alert.
• Owners: finance writes the content, internal communications schedules and sends it, the finance director approves.
• Measures: alert read rate, guide page views, support tickets and the share of June claims submitted without support.

How do you choose the right channels?

Choose channels by matching each message to how urgent it is and where the audience works. Routine updates suit newsletters and the intranet; time-sensitive or mandatory messages need channels employees cannot miss, such as desktop alerts, and frontline staff need digital signage or mobile. Most plans use several channels together.

• Routine news: a regular newsletter. Our guide to employee newsletter ideas covers what to include and how to make sure each issue is read.
• Mandatory or time-sensitive messages: desktop alerts that appear on screen and can require acknowledgement, so you can show who has seen them.
• Ongoing reminders: a desktop ticker or corporate screensavers to keep a message visible without interrupting work.
• Employees away from a desk: digital signage in shared spaces and mobile notifications.
• Disruption and incidents: a separate, pre-agreed process. See the crisis communication plan guide.

How do you measure an internal communication plan?

Measure an internal communication plan against the objectives it set. Track reach and read rates for each channel, acknowledgement rates for mandatory messages, and short pulse surveys on understanding. Review results quarterly, compare them with the baseline you recorded at the start, and adjust channels, timing or messages where the numbers fall short.

• Reach: how many of the intended audience received each message.
• Read and acknowledgement rates: who opened or confirmed each message, by department or location.
• Understanding: a one or two question pulse survey, using a tool such as Heed Survey.
• Outcome: the business result named in the objective, such as training completion or system adoption.
