10 Digital Communication Tools for Internal Communication to Facilitate Exchanges Within Your Company!

By

You want to share the latest business results with your colleagues to celebrate victories? Reveal a new ambitious project? Announce the date of the next company birthday dinner?

All of these actions fall under internal communication, that superpower often underestimated that allows you to relay key information, stay in touch, reinforce company culture, and unite your teams around a common goal (or at least around a pizza).

Explore our examples of digital tools and some tips to make your internal communication both smooth, effective, and maybe even a bit fun!

What is a digital internal communication tool?

Un outil numérique de communication interne est une technologie ou solution digitale qui vous permet de structurer et d’automatiser les échanges au sein de votre entreprise. Ça, c’est pour la définition officielle.Pour simplifier, on dira que c’est un outil digital, une plateforme ou une application utilisés pour communiquer entre collaborateurs, managers et dirigeants au sein d’une entreprise.

10 Examples of Digital Internal Communication Tools

There is a multitude of digital tools that can facilitate multichannel communication and collaboration within your company. Here's a list (non-exhaustive) of 10 families of tools that are very useful for streamlining everyday communication!

The Intranet Portal

The intranet network centralizes all the important information in your company. These range from institutional resources, such as the company’s organizational chart, internal regulations, or training modules, to news and management messages. Unlike the bulletin board, you can deliver more confidential details here, as the intranet is only accessible to employees with a username and password.

Example solution: SharePoint.

Internal Social Networks

More fun and less suited to official communications, your company’s social networks facilitate informal conversations between your employees. They allow, for example, the creation of thematic groups gathering employees working on the same project. Of course, we’re talking about internal communication platforms, like Yammer, and not your LinkedIn, Facebook, or Instagram accounts meant for public communication.

Example solution: Microsoft Viva Engage (formerly Yammer).

Messaging Apps

Messaging apps allow quick exchanges ("The meeting starts in 5 minutes!") or more informal discussions essential to team cohesion ("Who's available for lunch?").

Examples of solutions: WhatsApp Business, Workplace, and Microsoft Teams.

Document Sharing Software

More than just internal communication tools, document-sharing software facilitates collaborative work within teams. People working on the same project can co-edit shared documents, add comments visible to everyone, or make real-time synchronized changes. This way, every user has the same level of information at all times.

Examples of solutions: Google Workspace or Office 365 are the most well-known.

Synchronous and Asynchronous Communication Tools

Synchronous and asynchronous communication tools allow for sending instant or delayed messages (depending on the urgency of the information). They are mainly used to organize online meetings or video conferences. If your employees are spread across several locations or if part of your team works in a hybrid mode, you won’t be able to do without them!

Examples of solutions: Slack, Zoom, and Google Meet.

Project Management Software

As the name suggests, project management software facilitates coordination among stakeholders in a project. The manager can assign tasks to each team member and track their execution. A great way to have an overview of a project and ensure that everyone has the same level of information, whether they are working from the company’s premises or not.

Examples of solutions: Trello and Asana.

Survey and Poll Platforms

Have you ever wondered what your employees think of the company? What they would like to improve? Or, on the contrary, what they wouldn’t change for anything in the world? This is possible thanks to survey and poll platforms that allow you to give them a voice and gather their suggestions, reasons for satisfaction or dissatisfaction, and their feedback, all anonymously.

Example solution: SurveyMonkey.

Online Training Portals

The primary goal of online training portals is to encourage the personal and professional development of your employees by providing online educational resources. But have you thought about using them to communicate about internal programs? It’s possible! For example, you can create training modules following updates to your security policy or the launch of your new anti-discrimination strategy.

Examples of solutions: LinkedIn Learning or Udemy for Business.

Digital Onboarding Portals

The stars of HR services in recent years, digital onboarding portals facilitate the integration of new employees by offering them centralized access to a wide range of information about your organization, from the company history to HR documents, initial training, and integration paths. They represent a powerful internal communication tool offering a first entry point into your company culture.

Example solution: BambooHR.

Email and Email Signatures

Unavoidable, email is a very effective internal communication channel. You can use it to send official or more informal messages to all or part of your team. Your emails can even include a link directing to content from another medium, like an article from your newsletter or a post on your intranet portal. A small tip to stand out: personalize your professional email signatures.

How to Improve Your Internal Communication with Email Signatures?

Don’t know what a mail signature in Outlook (or any professional email platform) is? Yes, you do! It’s the small personalized text block that can be inserted at the bottom of each of your emails and those of your colleagues. It contains corporate information, such as the sender's name, position, and contact details, as well as the company logo, colors, or motto.

Carte de visite numérique reflétant l’identité de l’expéditeur et de l’entreprise, la signature de mail professionnelle constitue aussi un support de communication interne souvent sous-estimé.


Facilement personnalisable grâce à l’ajout d’une bannière mail, elle permet de diffuser efficacement certains messages ou d’orienter le destinataire de l’email vers d’autres contenus, comme votre réseau intranet, vos réseaux sociaux ou les contenus informatifs de votre newsletter.

For example, you can add a banner in your internal email signatures to:

  • Give more visibility to an event you're organizing. The banner can display a message like "Join us on March 12 for our annual seminar!";
  • Strengthen the company's identity and your employees' sense of belonging by including mentions that highlight your values. For example, if you've launched a new internal anti-discrimination program and want to raise awareness among your teams on this issue, you could add a message like: "For an inclusive company committed to fighting discrimination, let’s stay vigilant!";
  • Manage an internal crisis and reassure your employees. In this case, your message should be empathetic and indicate that the company remains committed: "We stand by you."

As with any internal communication action, don’t forget to follow some best practices, such as maintaining visual coherence between your banner and your brand image, regularly updating the information to avoid it becoming outdated, or prioritizing simple messages. For this, feel free to use a ready-to-use Outlook signature template like those offered by Letsignit!

What is the Best Internal Communication Tool?

Sorry to disappoint you, but there’s no one-size-fits-all answer to this question!

Le meilleur outil de communication interne est tout simplement celui qui répond le mieux à vos objectifs, à vos besoins et à vos contraintes financières, tout en garantissant la sécurité de vos données. S’il est en plus facile à implémenter dans votre workflow, vous aurez tout gagné.

What Are Other Internal Communication Media?

Non-Digital Written Media

Written media (also called internal communication touchpoints by purists) includes all paper channels through which information circulates, black and white, within your company. From pages in your internal newspaper to informational posters pinned at the entrance of the cafeteria.

Commençons par le traditionnel tableau d’affichage. S’il a un peu perdu de sa superbe avec la montée en puissance du digital, il reste un support de communication interne efficace lorsqu’il est placé dans un endroit stratégique. Par stratégique, comprenez un lieu de passage bien en vue, comme le mur qui jouxte la machine à café ou l’entrée de la cuisine collective.

If some of your employees don’t work on computers, such as those in manual jobs or on production lines, the bulletin board is sometimes one of the only internal communication channels available.

But when should you use it? You could, for example, pin:

  • Mandatory documents that need to remain visible, such as safety instructions, collective agreements, or your telework charter;
  • Announcements for upcoming major events, ranging from the agenda of the monthly info meeting to the date of the next seminar, or the theme of the annual dinner;
  • Less important messages such as "I left my charger in the Eiffel Room" or "A yellow hat was found on the sofa in the relaxation area."

Autre exemple de support : le bon vieux journal interne (ou newsletter interne) au format papier ! Il vous permet de partager régulièrement les actualités de l’entreprise, comme les résultats commerciaux mensuels, le lancement d’un nouveau produit ou service, l’état d’avancée d’un grand chantier ou le parcours professionnel des dernières personnes qui ont rejoint la société. Ce support vous aide à maintenir un lien direct avec vos collaborateurs et à cultiver leur sentiment d’appartenance à l’entreprise.

Oral Communication, Simply

It’s often forgotten, but oral communication is probably the most obvious communication channel. You know, those times when you or your managers speak at an info meeting or team lunch to announce good news (and not-so-good news…). Or those speeches where you subtly deliver key messages during a seminar, team-building event, or the company’s traditional annual or Christmas party.

More broadly, oral internal communication is also what you use daily, without even realizing it, during your informal exchanges with your employees, which helps strengthen the bond with your teams.

How to Communicate Better Internally?

Comment mieux communiquer en interne

The effectiveness of an internal communication tool largely depends on your internal communication strategy, your managerial practices, and your ability to leverage its potential.

Here are some examples of best practices to optimize your internal communication:

  • Establish an internal communication strategy, built step by step, based on the Maslow’s hierarchy of needs;
  • Avoid using too many communication tools, as this can make your strategy counterproductive. Instead, select the most useful tools based on your objectives, defining which platform or channel to use for each type of communication. For example, reserve emails for institutional communications, Slack for quick exchanges, and Zoom for strategic meetings;
  • Find the right balance in your internal communication to maintain frequent contact with your team without overwhelming them with information;
  • Carefully craft your internal communications by prioritizing short, transparent messages that are accessible to everyone!;
  • Encourage the sharing of ideas by regularly giving your teams a voice and fostering active listening to gather their needs;
  • Encourage the use of email signatures and banners to communicate key messages about your internal campaigns, safety guidelines, or new policies on various topics. A great way to spread information without overloading your emails;
  • Train your managers and employees in the proper use of internal communication tools.

It's your turn!
