16 of May, 2025

Do you usually wonder what the most effective types of internal communication are? With this content, we’re going to make it much clearer which to use. Indeed, contact with your first audience — your own employees — is critical for corporate success.

What functions does internal communication serve?

Internal communication involves exchanging messages with the personnel of an organization. It is necessary for multiple reasons that you should consider when deciding which types of internal communication channels suit you:

Provide useful information for the performance of the activity.
Receive feedback and valuable contributions from employees.
Strengthen collaboration among colleagues
Create a sense of community, belonging, and corporate involvement.
Motivate professionals.
Leverage, captivate and retain talent.
Make better decisions, with more and better information.
Optimize the overall work environment.

In short, the purpose is dual. First, to allow useful data and content to flow throughout the organization. Second, to encourage its members to feel important parts of the company.

Types of internal communication and channels

It is up to you to establish a strategic plan with the most appropriate types of internal communication. Each company has its peculiarities. Consequently, it is not possible to set a single guideline for all.

When you do so, also consider the difference existing among these three internal communications: horizontal, descendente and ascendente.

All in all, these five types of internal communication channels have proven their effectiveness in them. Without a doubt, you have to consider them when carrying out your planning.

1. E-mail

Take a look at this data: according to Statista’s studies, 4030 million people are using e-mail in 2023. These same analyzes predict an increase of 50 million more in just one year.

It is a popular, direct, and personalized medium, as well as economical. It’s part of the daily work, and of course, arouses interest depending on its source.

To improve its effectiveness, we recommend generating newsletters, whose visual impact is much higher. Moreover, it allows you to better structure the information, including links, headlines, highlights, and captions.

E-mail has a significant advantage: the recipient can decide when to check it. Even keep the information and review it whenever he wants.

In this sense, having a CRM will be very useful. The key to success lies in managing your database well. This technological tool greatly facilitates that work.

When should you include email among your types of internal communication? Especially to provide practical information, meetings, company policies, and corporate values.

2. Internal chat

If you want to promote trust and transparency in your teams, the mobile phone is an ideal channel for your internal chat. It is, without a doubt, the device that we all use every day. It’s always with us and, therefore, ensures immediacy and convenience.

Its functionality is maximum, especially in the exchange of everyday messages. Do you know the meaning of asynchronous communication? This term originates from telecommunications.

It’s the one established between people at different times. Meaning, when there is not physical contact between them or temporal coincidence.

In this relational universe, the chat is one of the most effective types of internal communication. It is ideal for sending reminders, alerts, instructions, and meetings. It also helps comment on reality and encourages feedback.

3. Employee portal

This tool involves creating a private website, accessible only to the professionals of the organization. Through a restricted entry intranet, you can decide what content you make available to its users.

In this resource, all forms of communication are welcome. From downloading files to reading posts, watching videos, or infographics.

Also, it is a space enabled for communicational exchange between its participants. So, it allows the inclusion of chats, ratings, and comments.

It’s also ideal for including a suggestion box, either anonymous or nominal. With it, upward communication flows extraordinarily and provides very valuable information for better decision making.

Isn’t it great to receive opinions, concerns, perceptions from your professionals in real time? Even this tool can be used to generate new ideas and solutions to certain corporate problems.

4. Meetings, one of the types of internal communication

Technology can’t, and shouldn’t, replace physical presence. Human communication includes extralinguistic nuances that are good to preserve and strengthen. Verbal language, sharing emotions, and fostering human connection depend on contact between people.

It must be used to inform, train, negotiate and coordinate goals or action plans. Likewise, they have a motivating effect when you manage them well.

However, improvisation is a very dangerous distorting factor. You need to prepare and work on them conscientiously. Otherwise, they become a collective waste of time that can destabilize more than unite.

Electronic agenda tools and video calls are technological resources that will help you make the most of them.

5. Employee manual

It serves to provide the professional with all the information he needs. It is very common, and necessary, when starting to work. The so-called welcome manual maximizes each landing in the company.

Actually, this information can be delivered to the interested party through different types of internal communication channels. Specifically, the employee portal, email, or even the corporate chat.

Its main virtue is that it gives the worker great autonomy. That said, it must be exhaustive, agile, clear, and specific.

At this point, you know what types of internal communication you should implement. It is also important to optimize their management and application. For this, having the right technological tools will be beneficial.
