How to write an internal communication strategy & get results

Most internal communication strategies fail for a fairly simple reason: organisations focus on sending communication rather than making communication genuinely relevant to employees.

Messages are distributed across email, intranets, chat tools, meetings, and leadership updates, yet employees still miss important information, feel overloaded, or disengage from communication altogether.

At Oak Engage, we call this the Reach Relevance Gap: the gap between communication being delivered and communication actually being useful, timely, and actionable for employees.

To address this challenge, we developed the Reach Relevance Framework, built around four core areas that determine whether internal communication is truly effective:

• Reach
• Relevance
• Reinforcement
• Response

Organisations that improve these four areas are significantly more likely to improve employee engagement, reduce communication overload, strengthen frontline communication, and create better organisational alignment.

This guide explains how to write an internal communication strategy using the Reach Relevance Framework.

The Reach-Relevance framework

The Reach-Relevance Framework is a communication effectiveness model developed by Oak Engage to help organisations improve how employees receive, engage with, and act on internal communication.

The framework was developed in response to a growing problem in modern workplaces: organisations are sending more communication than ever, but communication effectiveness is often declining.

This challenge is what Oak Engage refers to as the Reach-Relevance Gap.

The Reach-Relevance Gap describes the disconnect between communication distribution and actual employee engagement.

In many organisations:

• communication is technically delivered
• but employees do not meaningfully engage with it

This is particularly common in organisations with:

• frontline employees
• multiple locations
• fragmented communication tools
• high volumes of information
• disconnected systems
• poor communication targeting

According to Oak Engage’s Reach-Relevance Framework, effective internal communication depends on four core principles:

• Reach
• Relevance
• Reinforcement
• Response

1. Reach

Reach refers to whether employees can actually access communication easily.

This sounds obvious, but it is one of the biggest communication problems organisations face.

Many employees:

• do not regularly access email
• work across multiple sites
• rely on personal devices
• operate in shift based environments
• have limited desktop access

Traditional intranet and email strategies often fail frontline employees entirely.

A strong communication strategy should identify:

• where employees work
• how employees access information
• which devices employees use
• which communication channels employees actually engage with

This is why mobile first communication strategies have become increasingly important.

If communication only works for office based employees, the strategy is incomplete.

Questions to ask:

• Can frontline employees access communication easily?
• Are communication channels accessible across devices?
• Are employees relying on unofficial channels like WhatsApp?
• Are important updates reaching operational teams quickly?

2. Relevance

Relevance refers to whether communication feels useful and important to employees.

One of the fastest ways to destroy engagement is sending every employee the same generic communication regardless of role, location, or priorities.

Employees increasingly expect:

• personalised communication
• role relevant updates
• targeted information
• localised content
• communication that directly affects their work

According to the Reach-Relevance Framework, low relevance is one of the biggest causes of communication overload.

When employees repeatedly receive irrelevant communication, they gradually stop paying attention altogether.

A strong internal communications strategy should therefore include:

• audience segmentation
• targeted communication
• role based messaging
• location based communication
• prioritisation rules

This helps organisations reduce noise and improve engagement quality.

Questions to ask:

• Is communication targeted appropriately?
• Are employees receiving too much irrelevant information?
• Are updates personalised by department, role, or location?
• Do employees understand why communication matters to them?

3. Reinforcement

Reinforcement refers to how organisations repeat and strengthen important communication over time.

Many organisations treat communication as a single event:

• send the update
• move on
• assume employees understood it

But important communication usually requires reinforcement across multiple touchpoints.

Employees are busy.
Messages compete for attention.
Single announcements are easily forgotten.

Strong internal communication strategies reinforce key messages through:

• manager communication
• leadership visibility
• repeated campaign messaging
• multiple communication formats
• social engagement
• video communication
• operational workflows

For example:

• a policy change may require leadership communication
• manager reinforcement
• FAQ content
• mobile notifications
• mandatory reads
• reminder campaigns

Communication effectiveness improves when important information appears consistently across the employee experience.

Questions to ask:

• Are important updates reinforced consistently?
• Are managers helping communicate key priorities?
• Are employees reminded about critical information?
• Are different communication formats being used effectively?

4. Response

Response refers to whether organisations can measure communication understanding, engagement, and impact.

This is where many internal communications strategies struggle.

Most organisations can measure:

• email sends
• open rates
• page views

But these are often surface level metrics.

Modern internal communication strategies increasingly focus on deeper engagement insights, including:

• employee interaction
• communication reach by audience
• behavioural engagement
• content performance
• employee sentiment
• communication adoption trends

Without meaningful measurement, organisations cannot identify:

• which communication works
• which audiences are disengaged
• where communication gaps exist
• whether employees actually understand important information

According to the Reach-Relevance Framework, response is what closes the communication loop.

Questions to ask:

• Can communication effectiveness be measured?
• Which channels perform best?
• Which employees are disengaged?
• Are employees acting on communication?
• Can leadership prove communication impact?

What is an internal communications strategy?

An internal communications strategy is a structured plan designed to help organisations communicate effectively with employees across departments, locations, and roles.

A successful internal communications strategy typically includes:

• communication objectives
• employee audience segmentation
• communication channels
• leadership communication plans
• frontline communication methods
• employee feedback mechanisms
• governance and approval processes
• measurement and analytics

The goal of an internal communications strategy is to ensure employees:

• understand company priorities
• receive important updates
• feel connected to the organisation
• can easily access information and resources
• understand how their role contributes to wider business goals

Modern internal communication strategies must also support both desk based and frontline employees equally.

This is particularly important because many traditional communication strategies were built primarily around email and desktop access, creating major communication gaps for frontline workers.

Why internal communication strategies fail

Many internal communication strategies fail because organisations confuse communication activity with communication effectiveness.

Publishing more updates does not automatically improve employee communication.

According to Oak Engage’s Reach-Relevance Framework, most internal communication strategies fail for four main reasons:

This creates the Reach-Relevance Gap.

For example:

• a company sends an all employee email
• the message technically reaches inboxes
• frontline workers never access it
• desk based employees skim past it
• managers fail to reinforce it
• leadership assumes communication succeeded

In reality, communication visibility and communication understanding are completely different things.

Modern employees are also overwhelmed by:

• too many channels
• fragmented tools
• duplicated updates
• excessive notifications
• unclear priorities

The result is communication fatigue.

Employees stop paying attention because everything feels equally urgent.

This is why modern internal communication strategies increasingly focus on communication clarity, targeting, and measurable engagement rather than simply increasing communication volume.

How to write an internal communications strategy

Once organisations understand the Reach-Relevance Framework, they can begin building a practical internal communications strategy.

Step 1: Define communication objectives

Start by identifying what the strategy is designed to achieve.

Common internal communication objectives include:

• improving employee engagement
• increasing leadership visibility
• reducing communication overload
• improving frontline communication
• supporting organisational change
• increasing alignment across teams
• improving operational communication
• strengthening company culture

Communication objectives should be measurable wherever possible.

Step 2: Identify employee audiences

Different employees need different communication.

Segment audiences based on:

• department
• role
• location
• device access
• working environment
• communication preferences

This helps improve communication relevance and reduce unnecessary noise.

Step 3: Audit communication channels

Most organisations already use too many communication channels.

Audit:

• email
• intranet platforms
• chat tools
• meetings
• mobile communication
• digital signage
• social platforms
• operational systems

Identify:

• which channels employees actually use
• where communication duplication exists
• where communication gaps exist
• which channels frontline employees rely on most

Step 4: Define communication governance

Strong governance improves communication consistency.

This should include:

• communication ownership
• approval workflows
• publishing standards
• crisis communication processes
• leadership communication responsibilities

Without governance, communication often becomes fragmented and inconsistent.

Step 5: Create communication measurement plans

Measurement should be built into the strategy from the start.

Track:

• communication reach
• engagement trends
• employee feedback
• content interaction
• adoption rates
• campaign effectiveness

Modern employee communication platforms increasingly provide analytics that help organisations move beyond vanity metrics.

Common internal communication strategy mistakes

Treating email as the strategy

Email is a channel, not a communication strategy.

Many frontline employees rarely access email consistently.

Sending too much communication

Communication overload reduces engagement.

Employees stop paying attention when everything feels urgent.

Ignoring frontline employees

Many organisations unintentionally build communication strategies around desk based employees only.

This creates major visibility gaps across frontline workforces.

Measuring only open rates

Opens do not equal understanding.

Communication measurement should focus on engagement quality and behavioural impact.

Failing to personalise communication

Generic communication reduces relevance and increases disengagement.

Targeted communication is significantly more effective.

How modern employee communication platforms support strategy

Modern employee communication platforms help organisations reduce the Reach-Relevance Gap by combining:

• communication
• engagement
• analytics
• mobile access
• integrations
• governance
• AI powered targeting

In one centralised platform.

Platforms like Oak Engage help organisations:

• reach frontline and desk based employees
• personalise communication
• reinforce key updates
• measure communication effectiveness
• reduce fragmented communication channels

Modern platforms also increasingly use AI powered personalisation to improve communication relevance and reduce information overload.

This helps organisations move away from mass communication and towards more targeted employee experiences.

FAQs

• leadership communication plans
• frontline communication approaches
• employee feedback processes
• governance and ownership
• measurement and KPIs
• crisis communication planning
• communication technology and platform decisions

Modern strategies increasingly include mobile communication and AI powered personalisation for frontline and distributed workforces.

What is the Relevancy Gap in internal communication?

The Relevancy Gap is a communication problem where employees receive information that is not relevant to their role, location, priorities, or day to day work.

Over time, employees begin to ignore communication because too much of it feels generic, repetitive, or disconnected from what actually matters to them.

The Relevancy Gap Framework, developed by Oak Engage, explains why organisations often struggle with communication overload, missed updates, low engagement, and poor frontline reach despite sending more communication than ever before.

Reducing the Relevancy Gap typically requires organisations to improve targeting, simplify communication channels, personalise content, and make communication easier to access across both desk based and frontline employees.

How do you measure internal communication effectiveness?

Internal communication effectiveness is usually measured using a combination of:

• employee engagement metrics
• message reach and readership
• platform adoption
• click through rates
• feedback participation
• survey results
• employee sentiment
• operational alignment
• reduction in communication overload

Many organisations now use employee communication platforms with analytics to measure communication performance more accurately.

What are the biggest internal communication challenges?

Common internal communication challenges include:

• employees ignoring emails
• disconnected frontline teams
• too many communication channels
• inconsistent leadership communication
• poor visibility into communication impact
• information overload
• low employee engagement
• fragmented workplace tools

These problems are particularly common in large or distributed organisations.

How often should an internal communication strategy be updated?

Most organisations should review their internal communication strategy at least annually.

However, communication strategies should also evolve when:

• business priorities change
• organisations grow rapidly
• employee engagement drops
• new communication tools are introduced
• workforce structures change
• frontline communication challenges increase

Internal communication strategies should remain flexible rather than static documents.

What is the best channel for internal communication?

There is no single best internal communication channel.

Most organisations use a mix of:

• employee intranets
• mobile employee apps
• email
• Microsoft Teams
• digital signage
• leadership updates
• video communication
• employee communities

The best approach depends on workforce structure, communication goals, and whether employees are desk based or frontline workers.
