Internal Communication in the Workplace:
Strategies, Tools, and Best Practices

In a context of digital transformation and hybrid work models, internal communication is emerging, more than ever, as a lever for performance. As employees frequently work remotely from one another, digital tools streamline the flow of information, contributing to collective success. But be careful—not all tools are created equal.

Do you want to implement an effective internal communication strategy? In this article, Mozzaik presents the strategies, tools, and best practices to adopt to achieve this goal. Enjoy the read.

Why Has Effective Internal Communication Become Essential?

The importance of internal communication is now well established. The smooth circulation of information between management and employees, as well as between colleagues, is a driver of cohesion, productivity, and talent retention.

The link between communication and engagement is quite clear: bringing organizational values and strategic objectives to life for employees allows them to embrace these values and feel a sense of belonging to the group.

The relationship between communication and performance is also evident: employees work more efficiently when they understand how their company operates and what its objectives are. They make fewer mistakes, experience fewer conflicts, collaborate more smoothly, and develop collective intelligence.

The State of Business Communication Report published in 2024 by Harris Poll and Grammarly highlights the concrete impacts of effective internal communication. According to this study:

  • 43% of business leaders associate effective communication with more successful business transactions, 51% with increased customer satisfaction, 45% with a better brand reputation, and 33% with cost reduction.

  • At the same time, 58% of employees believe that smooth internal communication improves their job satisfaction and relationships with colleagues, 55% say it boosts their confidence and productivity, and 48% feel it reduces their work-related stress.

Conversely, poorly structured internal communication hinders organizations. When employees are overwhelmed with information or lack the necessary details to perform their jobs, collaborate, or understand company culture, performance is directly impacted. As a consequence, according to Grammarly’s previous report (2022), internal communication issues cost American companies approximately $1.2 trillion annually.

How to Build an Effective Internal Communication Strategy?

Streamlining and optimizing information sharing within your company is a matter of overall performance. To ensure you achieve this important goal, you must implement a structured and effective internal communication strategy. Here’s how:

#1 Analyze the Current State: Internal Communication Audit and Field Feedback

The first step in creating an internal communication plan is to analyze your organization’s current practices to identify strengths and weaknesses. In this perspective:

  • Observe usage data for your existing internal communication channels. For instance, examine usage statistics for your company blog, internal newsletter, intranet, or display systems.

  • Collect feedback from teams to refine your internal communication audit. A survey and individual or group interviews will help you understand how employees use digital tools (intranet, collaborative communication app, etc.) and physical communication supports (welcome brochure, bulletin board, etc.). You’ll also gain a more comprehensive understanding of employees’ needs, expectations, and complaints (information silos, information overload, etc.).

#2 Define SMART Objectives Aligned with Organizational Goals

Once the assessment is complete, identify the goals you want to achieve through your internal communication plan. These objectives must be SMART, meaning:

  • Specific, i.e., precise and understandable by the entire “internal communication” team;

  • Measurable using performance indicators to evaluate the effectiveness of your actions at every stage of the implementation;

  • Achievable in terms of your technical, human, budgetary, and time resources;

  • Relevant, or rather consistent with your organization’s strategic axes (increase productivity, improve customer satisfaction, reduce operational costs, etc.);

  • Time-bound, with a defined start and end date.

A SMART objective in corporate internal communication could be: “Increase employee engagement to reach an eNPS score of 10 within 6 months by implementing an internal communication campaign around organizational values.”

#3 Identify Internal Targets and Segment Them

The third step in building a structured and effective internal communication strategy is to identify your internal target audiences and then segment them, i.e., divide them into homogeneous sub-groups in order to tailor your message, communication frequency, and channels accordingly.

Depending on the previously defined objectives, your internal communication strategy may target all employees or only specific categories, such as managers, field staff, or new hires. These internal audiences each have specific characteristics. For instance, head office employees have access to a desktop computer and email, while store employees may only have a smartphone and a shared PC.

To effectively address these various target audiences, you need to get to know them. To do so, use the marketing method known as “personas”: create a profile for each of your typical “internal clients.” Take a sheet of paper and note their role, communication expectations, preferred information channels, and role in information circulation. If you work in the industrial sector, one of your internal personas might look like this:

“Marc, field technician, 45 years old:

- Position: maintenance technician, site-based, frequently traveling;

- Location: regional plant, little connection to headquarters;

- Information habits: reads bulletin board in break room, listens to team briefings each morning, rarely accesses the intranet;

- Barriers: no personal or work computer, rarely checks professional emails, feels disconnected from ‘corporate’ communications;

- Expectations: only wants information relevant to daily work, to be quickly informed of changes (procedures, safety, schedule), to feel recognized and valued for fieldwork;

- Preferred channels: team meetings led by manager, displays in high-traffic areas, oral communication or simple SMS/mobile app messaging;

- Role in information circulation: indirect relay, heavily relies on manager for information, but can influence colleagues if he finds information useful or credible.”

#4 Define the Messages, Channels, and Communication Schedule

The fourth step in implementing your internal communication strategy is to define the messages to be shared, the communication channels to be used, and the publication frequency for each internal audience to effectively achieve your objectives. To this end:

  • Define the key messages you wish to deliver to employees in order to meet your strategic goals. To determine the message content, ask yourself what each audience segment should understand, retain, or do after receiving the information. Also ensure the form of your communication is adapted to each employee category (vocabulary, tone, structure, etc.). In any case, favor short, clear, and concrete messages.

  • Choose communication channels suited to each internal target and to the type of message you want to convey. For urgent practical information (e.g., schedule changes) for field teams, opt for SMS or a smartphone-accessible intranet notification. That said, embrace multichannel communication. Diversifying internal communication channels will help balance top-down, bottom-up, and horizontal communication and foster employee engagement. You can, for instance, combine internal newsletters, suggestion boxes, and a community hosted on your enterprise social network.

  • Create an editorial calendar. This document will help you plan your internal communication activities. It enables you to space out publications, organize content production, and avoid information overload. Depending on your strategic goals, combine occasional highlights (quarterly results announcement, executive committee address, etc.) with more regular touchpoints (e.g., monthly HR newsletter).

#5 Manage, Evaluate, and Adjust the Internal Communication Strategy

Once your internal communication strategy is launched, regularly evaluate its results. To do so:

  • Implement and track relevant performance indicators such as event participation rates, internal newsletter open rates, or digital tool adoption rates.

  • Send satisfaction surveys to your different target audiences to understand how they engage with your communication materials and gather ideas to better meet their expectations and needs.

After collecting and analyzing both qualitative and quantitative data, use it to optimize your internal communication strategy and more effectively reach your strategic goals.


RECAP: The 5 Steps to Build an Effective Internal Communication Strategy:

  1. Conduct an audit of your company’s current internal communication practices using digital tool usage statistics and field feedback;

  2. Define SMART (Specific, Measurable, Achievable, Relevant, and Time-bound) objectives for your future internal communication strategy, ensuring they align with organizational goals;

  3. Identify and segment your internal target audiences to determine what message to send to which employee category, how often, and through which communication channel;

  4. Define the messages, communication channels, and schedule to effectively engage each internal audience and achieve your strategic goals;

  5. Manage your internal communication strategy, evaluate its results using performance indicators and feedback, and optimize actions based on the collected data.

Tools and Levers to Improve Internal Communication in the Workplace on a Daily Basis

Several solutions can help you maximize the results of your internal communication strategy. These generally fall into two categories: digital tools and managerial levers. Let's take a closer look.

Digital Tools: Intranet, Messaging, Internal Social Networks

Thanks to digital solutions, internal communication has taken on a new dimension in recent years. Employees can now access company news, interact with one another, and share resources in a smooth and secure way—even when they’re not in the same location. More specifically, three types of digital tools have become absolutely essential in the field of internal communication:

  • The intranet. Software such as Microsoft SharePoint enables organizations to build an internal network, modeled after the internet, exclusively accessible to their members. On this online platform, employees can find company news, HR information, and document libraries. A turnkey solution like Mozzaik365 simplifies the creation of a collaborative, personalized, and engaging intranet. The internal communication team can run internal communication campaigns directly from the interface, precisely target the audiences who will receive their messages, and effectively analyze the results of their actions thanks to integrated artificial intelligence (AI) features.

  • Instant messaging applications. Apps such as Microsoft Teams and Slack allow employees to interact and share documents either one-on-one or in teams, in real-time or asynchronously. These solutions streamline cross-functional communication between employees, regardless of whether they belong to the same department. To exchange information and resources quickly and in an organized manner, members of a working group can, for example, meet in a Teams team and organize their interactions within themed channels (budget, schedule, customer complaints, etc.).

  • Enterprise social networks such as Viva Engage (formerly Yammer) are platforms where members of the organization can create personal profiles, participate in interest-based communities, share ideas and content in a news feed, respond to others' posts, and of course engage in discussion via a “comments” section. This digital tool, modeled after Facebook, promotes communication between employees as well as between employees and leadership. It breaks down silos and builds connections, strengthens internal cohesion, and enhances employee engagement. It is also ideal for collecting feedback in the workplace, as it enables easy distribution of surveys.

Managerial Levers: Transparency, Feedback, Rituals

Successful internal communication relies on effective digital tools but also on managerial levers. Managers are indeed essential intermediaries and facilitators. They help disseminate information, ease its upward flow through feedback collection, and foster an environment conducive to interaction. To streamline internal communication within your company, you need to fully engage them. To do so:

  • Clarify the behaviors expected of managers, such as: clearly and transparently relaying key messages, adopting a supportive listening attitude, encouraging dialogue in meetings, recognizing employees who provide constructive feedback, and promoting internal communication channels within their teams.

  • Encourage managers to strengthen their communication skills (active listening, meeting facilitation, giving feedback, etc.) and to learn how to use internal communication tools.

  • Encourage managers to implement rituals that foster both formal and informal internal communication. This might involve asking employees how they’re doing each morning or at the start of team meetings, scheduling a weekly team lunch, or organizing a monthly group feedback session.

Best Practices and Indicators to Manage Internal Communication

In addition to digital internal communication tools and managerial levers, several best practices can help you build a successful internal communication strategy, in particular:

Choose Engaging Content

Certain formats are particularly effective at capturing employees’ attention. These include:

  • Short videos, possibly in motion design, which can be watched effortlessly and convey key messages effectively;

  • Infographics that visually summarize complex concepts in a concise, clear, and pleasant way;

  • Internal podcasts that add a human touch and can be easily consumed, for example while commuting;

  • Quizzes that are both fun and engaging, as they invite employees to test their knowledge in a playful way.

Leverage Employee Advocacy and Employee Generated Content (EGC)

A great way to strengthen internal communication in your company is to involve employees in creating and sharing content with their peers. To this end, you can:

  • Encourage employees to share your messages via their internal communication channels, such as their profile on your enterprise social network. This practice of turning employees into ambassadors is called Employee Advocacy.

  • Invite employees to create content, for example by participating in your internal podcast or sharing a post on the internal social network. This is known as employee generated content (EGC).

These two practices increase the engagement of involved employees, as they gain visibility and recognition from their peers. They also boost engagement among internal audiences. Why? Because content shared by fellow employees is perceived as more authentic and therefore receives more reactions.

Adopt a Balanced Communication Frequency

To ensure your internal communication strategy meets its objectives, adopt a balanced publication rhythm. Communicate regularly enough so employees have the information they need to work and feel connected to your organization. However, avoid over-communication, which can lead to disengagement. To achieve this, segment your audience carefully and only send each message to the relevant group. For example, there’s no need to bother field employees with an announcement that only concerns headquarters.

Implement an Evaluation and Continuous Improvement Approach

Lastly, to determine whether your internal communication strategy is working—and to maximize your chances of meeting your objectives—adopt a continuous evaluation and improvement approach. In this context:

  • Track quantitative indicators provided by your internal communication tools, such as intranet page views or the number of views on your posts within the internal social network. These metrics will help you identify the strengths and weaknesses of your communication efforts. A very low click-through rate on your internal newsletter might, for instance, indicate an unappealing email subject line, poor timing, or an overly frequent sending schedule.

  • Monitor qualitative indicators, particularly spontaneous employee feedback, responses gathered during internal surveys, and feedback from managers. These insights will help you better identify the needs and obstacles of your target audiences, as well as gather concrete ideas to optimize your internal communication efforts.

  • Establish a continuous improvement loop by analyzing your internal communication KPIs to draw actionable insights, using them to adjust your strategy, and then repeating the process cyclically.

Use Case: Two Companies That Transformed Their Internal Communication

Some companies provide concrete examples of successful internal communication strategies. This is particularly true for the French SME Armonia and the American multinational Coca-Cola. Let’s take a closer look at these inspiring use cases.

ARMONIA: Fewer Internal Emails and More Engagement Thanks to SharePoint and Mozzaik365

Armonia, a major player in Facility Management with 12,000 employees, was facing fragmented internal communication. Without a centralized intranet, information useful to employees was scattered across various channels, resulting in heavy reliance on email, reduced efficiency, and ultimately, lower engagement.

To address these challenges, Armonia deployed a unified intranet based on SharePoint, modernized and enhanced with Mozzaik365 features. This platform enabled the company to centralize its communications and distribute information in a targeted way. Interactive dashboards and the social wall encouraged user engagement and boosted participation.

The feedback from Armonia has been overwhelmingly positive. And for good reason—the results observed following this digital transformation are compelling: 500 permanent employees log into the intranet daily, the number of internal emails has been reduced by 80%, and the consultation rate of internal content has doubled. Mission accomplished!

COCA COLA: A Stronger Company Culture Thanks to an Internal Podcast

Coca-Cola, with 700,000 employees worldwide, offers another example of successful corporate internal communication. The American multinational faced a challenge: aligning its teams with the strategic direction of its leadership—a critical move to maintain employee engagement.

To tackle this challenge, the U.S. division of the organization launched an internal podcast in 2019 called “Total Refresh.” In this publicly accessible show, two Coca-Cola employees interviewed seven North American executives. The aim: to talk about managing major changes (cultural, personal, and professional) in a transparent, human, and accessible way.

By leveraging a communication channel appreciated by employees and creating direct dialogue between staff and leadership, Coca-Cola managed to break away from rigid top-down communication, bring various stakeholders closer together, and reinforce company culture through shared stories.
