Effective communication is the foundation of every successful organization. Dispersed teams, remote workers, individual contributors, and those working within rigid hierarchies must all be able to instantly and effectively communicate with colleagues, managers, and all relevant stakeholders.


Far too often, the lack of a robust internal communication strategy is responsible for project delays, employee disengagement, and ultimately breakdowns. That’s where internal communication apps come into play. These platforms allow users to communicate directly, within groups or channels, share files, video calls, and collaborate, all within the tool.



What is Internal Communication?

Internal communication in business is all about sharing information, ideas, and thoughts within a company. It’s crucial for team success, enabling members to collaborate and work towards common goals.


Think of internal communication as the lifeblood of your business. It’s the flow of information that keeps everyone on the same page, working together to crush goals. A solid internal communication strategy maps out what the company wants to achieve and exactly how everyone will work together to get there.


In the old days, internal communication might have meant company-wide emails or bulletin boards. Now, internal communication apps are like walkie-talkies for your entire team. Imagine: no more information silos, just a smooth flow of ideas that keeps everyone in the loop and moving forward.


Below, we’ve curated our top picks for internal communication in the workplace and lay out their pros, cons. As new solutions come to the market, we will continually update it, so bookmark this page and check it often. Technology software moves at a fast pace, so the best solution for today might not be the best solution for tomorrow.



How we Chose the Best Internal Communication Apps for Business

We considered the following criteria when choosing the best internal communication apps for business:

  • Communication – Does the app allow for internal and external communication?

  • Collaboration – Does the app provide a platform for collaboration, such as file sharing and project management?

  • Ease of use – Is the app easy to learn and use?

  • Design – Does the app have a modern and user-friendly interface?

11 Best Internal Communication Apps for Business



1. Spike

Best Email Management Software Tools


Spike is an all-in-one productivity platform that delivers business chat for teams as part of a wider suite of work tools. It excels at serving as an instant messaging software in business because it’s built on top of something every business already uses: email.

Simple and Secure Internal Communication

Spike turns your average inbox into a supercharged instant messaging tool that’s easy to use because it looks and feels like a messenger application. The simplicity of email, a tool that practically every employee is already comfortable with, has been brought into the 21st century by stripping away all the unwanted clutter like headers and signatures.




What’s more, because Spike is based on open source protocols, layered over your email, it can work internally and externally with all stakeholders – no closed-silo communications here. This means whether you’re talking with colleagues about the latest project or doing customer support for your most important client, Spike’s got you covered.


Collaboration Goes Beyond Communication for Effective Businesses

Spike includes collaborative online notes with synchronized real-time editing available to both Spike users and anyone outside of your company who needs to be part of the project. Spike users can edit their Notes inside the Spike app, while non-Spike users can edit right inside of a web browser.


Spike also offers Groups, which allows your business to divide contacts by team, project, or anything else. These groups are then able to collaborate through email chat, file sharing, pictures, videos, GIFs, and more, and have the option to send voice messages or jump on a call at the tap of a button.



Align With Team Members for more Streamlined Collaboration

In the modern workplace, there are often things pulling us in a thousand different directions, which is in addition to our personal lives. Spike allows you to get your work life in order using tasks and to-do lists, so you can spend less time worrying about what’s on your plate.

Spike also enables users to align all their calendars in a single place to save swapping back and forth between different apps. All your team can then easily align their calendars from within their Inbox, where they’re already chatting!


Business Chat using Voice Messages

Instant messaging is a fantastic tool for businesses of any size, but nothing holds a candle to actually speaking when it comes to more complex communication. However, in the modern world of work, teams can be distributed across different cities, states, and time zones, so finding a time to talk can be impossible.


This problem is where Voice Messages shine! There is a reason there has been a steady growth in audio-only services in recent years, and business communication is no exception. Spike offers Voice Messages for when you need to be more expressive, all from within the same chat platform.

Business Chat with Video Meetings

Video meetings and business chat are used for two very different things. One is simple and fast – a quick and clean way to communicate something with a few lines of text. The other is useful when a topic needs further explanation, or a lot of back-and-forth discussion is inevitable.


They are different tools for different jobs. That’s why with Spike, you can seamlessly switch between the two. In the middle of a chat with a colleague? Simply hit the Video Meeting button if you need to hash out some details quickly.


Intuitive Design for Better Business Communication

Spike offers a simple modern design that creates a digital workspace with all of the tools needed for any business, including email, chat, group chat, file sharing, online Notes with collaboration, and more.


Through the use of a clean interface with all tools readily available, all employees can quickly and easily get to grips with Spike. Having everything in a single place, nobody gets lost in the web of apps other digital workspaces are based upon.


Business Chat – Where You Need It When You Need It

Spike is also cross-platform, meaning it works seamlessly on Mac, PC, Android, iOS, and even a web version so those on Chromebooks can use this instant messaging tool in the workplace. Spike has a free version for personal use and offers plenty of flexibility with pricing for business users.

Simple and Secure Business Chat with Spike

Spike is fast to deploy because a user only has to sign in with their existing Google Workspace or Microsoft 365 login to get signed up. A company IT department can easily deploy the Spike app to company devices to have everyone chatting in no time.


What’s more, once deployed, this business chat is always secure. Spike is ad-free and doesn’t rent, sell, distribute or monetize your data. Furthermore, message data is encrypted using AES-256 encryption, and the whole platform has passed a security audit by an independent security evaluator.

3. Slack

Instant Messaging Apps for Business


Slack has become a popular choice for teams and groups looking to use internal communication software for business. It’s a responsive solution for fast-paced working environments, but it has some significant limitations, mainly because it is only a chat app.

Third-Party Integrations to Boost Features

Slack does an exceptional job of third-party integrations, so you can create automations to send an alert to a Slack channel when a crash is observed in software or when an e-commerce store completes a sale, for example. This is in addition to other integrations that boost features such as Google Drive for file sharing.


Multiple Communication Channels

As with other business chat platforms, Slack has realized the power of incorporating other communications channels into its offering. In this case, Slack now provides video and voice calls between employees at a company from within the platform, making it simpler to jump on a call when a topic requires more discussion.


Unfortunately, for more robust video conferencing tools, Slack still requires third-party integrations from the likes of Zoom, Cisco Webex Meetings, or other providers. This means more subscriptions, more costs, and more hassle when navigating and remembering the various single-tool apps.


Staying Secure Under Salesforce?

Slack includes robust security features, but many Slack customers are concerned about how the platform might evolve now that a large company, Salesforce, has taken ownership. Pricing is usually a concern for existing customers when a larger corporation purchases a smaller one.

The Simplicity of Operations

From a simplicity perspective, Slack can be more complicated for teams to learn. It can be confusing what a direct message is and what is in a channel, and the privacy implications around that reality. If something is said in a channel on one day, a person could be added to the channel the next day and then see all that was said previously.

Does Slack Let You Communicate with Customers?

Slack is mainly aimed at internal communications, but it did recently build a solution to chat externally. However, it was panned for the lack of control for receiving messages from unwanted people.


That said, for internal use, Slack does work cross-platform, so it is available to your whole team regardless of whether they’re working on Mac, PC, Android, iOS, or through a web browser.


Slack as a Business Chat App

  • Communication – Slack is very focused on text chat but now offers video and voice calls as well. However, they are all for internal communication.

  • Collaboration – Slack users can collaborate on work through the use of third-party integrations.

  • Ease of use – there can be some difficulty in using Slack if your employees don’t have experience in a channel vs. DM platform.

  • Design – the design is clear but can be a little busy, especially as things expand

  • Security – Slack offers very robust security

  • Supporting platforms – Mac, PC, Android, iOS, and the web

  • Pricing – Slack offers free accounts, with Pro users paying from $6.67 per account/month and Businesses from $12.50 per account/month.



4. Microsoft Teams

Instant Messaging Apps for Business


Microsoft Teams is one of the newest solutions on the market as an internal communication tool in the business world. It was developed as a response to Slack becoming so popular in the workplace. Since Microsoft already has Microsoft Outlook, they now have multiple products aimed at communication, with Outlook focused on external communication, and Teams focused on internal communication.


Part of a Whole Ecosystem, but Somehow Still Separate

Microsoft Teams is part of an organization’s Microsoft 365 subscriptions, so it’s not nearly as easy to purchase if you are already using Google Workspace or other productivity tools since it is part of a larger solution.


What’s more, since Microsoft Teams is part of a multi-app suite, deployment becomes slightly more cumbersome. Employees have to learn and understand different products and check multiple apps throughout the day. Having too many places to check slows down other work as employees just spend their time keeping their inboxes from overflowing.


Video Conferencing

The other major component of Microsoft Teams, apart from chat, is video conferencing, and it does this very well. In addition, it offers powerful internal and external communication tools, including integrations with the other office apps for presenting work.


That said, it is one of the more confusing video meeting platforms out there with a relatively steep learning curve. In addition, users must have other Microsoft services integrated for some of the more advanced features, which can quickly become very challenging.


A Calendar in Microsoft Teams

Microsoft Teams also offers an integrated calendar, which can be used to organize employees’ time, specifically by planning video meetings on the platform. While different calendars can be combined, it is a challenging process for even the most tech-savvy members of your team.


Microsoft Teams is available cross-platform, so regardless of the types of devices your workplace uses, Teams is available as a native app or Microsoft 365 web edition.


How is Microsoft Teams for Business Chat?

  • Communication – Microsoft Teams offers chat channels as well as video and voice calls. While chat is internal, video conferencing can be used with anybody.

  • Collaboration – the most powerful collaboration tools come if your business integrates Office applications such as Microsoft Word.

  • Ease of use – Teams is considerably harder to use and deploy than other chat apps

  • Design – The design of Teams, when considered as a standalone platform, is clean and modern.

  • Security – Microsoft Teams is considered a very secure chat platform

  • Supporting platforms – Mac, PC, Android, iOS, and the web

  • Pricing – while Teams is technically free for Outlook users, most will get it as part of an Office 365 package which varies massively in price.

Pros and Cons of Instant Messaging for Business

Before your business dive into the world of chat apps, consider closely the key features outlined as well as some of the overall pros and cons:


  • Faster response time which means faster problem solving

  • Smoother communication for teams even when working remotely

  • Easier file sharing and storage

  • All around quicker than traditional email


  • If not built into email, it requires an entirely new software solution

  • Additional training and onboarding requirements

  • It can be overwhelming because it’s another inbox to manage and check



Having the right internal communication app for your business can differentiate between a productive remote workforce and a non-productive one. The right balance to find for your team is a solution that allows for seamless collaboration without becoming a burden.


Some of the effective use of internal communication software for business will come down to culture. An essential tip for all teams to remember is that instant messaging in business should be viewed as asynchronous. If a teammate is focused on a project, they can’t be expected to respond to every instant message as it comes in.


Chat apps allow for fast and fluid communication internally and externally. This allows remote teams to talk more naturally and make fast, productive decisions. However, a dedicated app might not be the best choice for your company since some integrated solutions offer other tools in addition to chat.

Business chat apps can offer fast communication for remote teams as well as other features to help productivity. That said, every business is different, so before committing to any platform, consider carefully what you need from an app, then look for those features.

There are a few things always worth considering before getting a new chat app, the most important of which are:

  • Communication options
  • Collaboration tools
  • Ease of use
  • Overall design of the platform
  • Security
  • Supporting OS (Mac, Windows, etc.)
  • Price
