The 15 Best Instant Messaging Apps for Businesses (Free and Paid Tools)

Instant messaging has soared in popularity in recent years. In fact, the number of worldwide instant messaging accounts is expected to top 9.5 billion by 2025.

There’s no doubt that your customers are using instant messaging platforms. The same goes for your team.

The real question is whether you’re maximizing instant messaging, also known as IM, to meet your business needs.

That is, connecting with your customers on their preferred channel, while also providing your team with a tool for efficient internal communication and collaboration.

So what exactly is instant messaging and what are the best instant messaging tools for businesses?

Read on to discover the top instant messaging apps you can use within your organization.

What Is Instant Messaging?

Instant Messaging

Instant messaging, also known as IM, is an online communication method that connects two or more people in real time for back-and-forth conversation. 

Instant messaging software has long been known for its direct peer-to-peer connections, pioneered by the now inoperative AOL Instant Messenger (AIM).

AIM, and other similar IM programs, initially allowed two ‘contacts’ to directly send and receive text-based messages, provided both users were online, logged on with the client and had access to each other’s unique screen names.

While most people view IM as a vehicle for sending direct messages, nowadays most instant messaging apps employ centralized servers that facilitate messages between users. Often, users access the platform by downloading the client’s application to their device of choice and registering with their phone number. In some cases, access to the network can be controlled by a network administrator.

In recent years, IM has expanded to include various communication features, not just for personal use, but for corporate environments. This development has brought a range of benefits to both individuals and companies, including better communication between coworkers and increased team productivity.

Top Instant Messaging Tools for External Business Communication

Now that you’re familiar with the definition of instant messaging, let’s explore the most popular instant messaging platforms your business can use for external communication.


Available on: Android, iOS, Windows, macOS, Web

WhatsApp is the most-used instant messenger app around. With 2 billion monthly active users, there’s a good chance your customers are using its texting, group chats, file sharing, and voice and video calls. There’s a group chat feature allowing all members or only admins to send instant messages.

WhatsApp also features business tools to connect enterprises with their customers. The WhatsApp Business App is intended for small companies and offers one-on-one communication with customers. It allows you to create product/service catalogs and automate, sort, and answer messages.

There’s also the WhatsApp Business Platform, which is aimed at medium and large organizations. It gives access to the WhatsApp API to help you deliver content at scale. Here are its most prominent features:

  • Send out promotional messages; 
  • Set automated messages;
  • Send notifications for order confirmations and shipments;
  • Receive orders right within WhatsApp;
  • Re-engage customers after abandoning the cart;
  • Boost customer support as a live chat solution;
  • Access metrics, like instant message delivery and response rate.


Facebook Messenger

Available on: Android, iOS, Windows, macOS, Web

As an IM app to boost your business’s external communication capabilities, Facebook Messenger is right on WhatsApp’s heels. Messenger is available in almost every country but is currently banned in China, Russia, and a few others.

Your business probably already has a Facebook page and even if your customers aren’t on Facebook, they’re probably on Messenger.

If that wasn’t enough, Messenger allows your business to leverage the power of instant messaging in a host of ways.

  • Generate leads via Messenger campaigns;
  • Boost customer service with the live chat plugin;
  • Produce scannable codes to bring new users directly into Messenger conversations with your business.

Messenger ad campaigns are priced individually through the Meta Ads Manager.



Available on: Android, iOS, Windows, macOS

If you’ve got customers in China, WeChat is a no-brainer. With more than 1.3 billion monthly active users, the app for messaging, social media, and e-payments is where your customers will be most accessible.

In addition to full messaging capabilities, you also get payment services, news, maps and more. Like Messenger, you can use WeChat to launch various marketing and ad campaigns.

WeChat is unique because it also doubles as an IM app for businesses. WeCom (formerly WeChat Work) is the dedicated internal communication and office automation face of the platform, used by industry throughout China.

Just keep in mind that using WeChat comes with inherent risks to privacy and the security of user data and information.


Available on: Android, iOS, Windows, macOS, Linux, Web

Telegram doesn’t boast the billion-strong user base other instant messaging services on this list do. That said, thanks to features like bots, secret chats, supergroups and the ability to send files up to 1.5 GB, the messaging app is gaining popularity among businesses, especially in countries with tight restrictions on messaging apps.

Several unique features can boost your lead generation, like public channels and groups, and supergroups allowing for up to 200,000 users per group.

Just know that Telegram chats aren’t encrypted by default – you have to manually turn on encryption. What’s more, Telegram’s client-side code is open-source, but its encryption protocol is homegrown and unverified by experts. Which could give you a false sense of security.


One of the original apps for instant messaging, Skype began in 2003 as a peer-to-peer platform for IM and calling capabilities. Skype still offers individuals and small teams reliable instant messaging, voice and video calling and screen sharing. It’s also great for calling landlines at majorly reduced rates.

If you’re after Skype messaging, but on a dedicated business network, Skype has you covered – for now. Skype for Business takes place on a separate network and you can invite regular Skype users to join. You get everything in the consumer-grade version, plus a whiteboard, video conferencing, personalized meeting URLs and the ability to record meetings.

Unfortunately, Skype for Business was retired by its parent company Microsoft Teams in 2021.

While Skype lives on, check out these Skype for Business alternatives, or explore the top instant messaging tools for internal communication listed below.

Available on: Windows, macOS, iOS, Android, Linux, Web

Like a walkie-talkie, Discord delivers real-time push-to-talk communication. It’s a unique twist on instant messaging software for businesses. Originally created to bring gamers a more interactive experience, Discord’s rich voice capabilities – paired with chat and screen sharing – have gained traction in the business world.

There are some differences, though. While many business messengers organize conversations into workspaces or chat rooms, Discord arranges them by ‘Servers,’ with all your Servers accessible on one interface.

Moreover, Discord’s voice option is fully separate from text-based messaging. Voice chat continues in the background, which you can mute through the push-to-talk feature. Clicking on a voice channel immediately starts communication with users.

Microsoft Teams

Microsoft Teams
Available on: Windows, macOS, iOS, Android, Web

With 300 million monthly active users, Microsoft Teams overtook Slack as the king of instant messaging for business.

Teams features a few key selling points, one being its in-messaging word-like formatting. You can change font styles, and create bulleted lists within each IM. Then there’s Teams’ deep integration with Office 365. Collaboration within the entire Microsoft Office toolkit without leaving the app makes it great for the corporate environment.

Two different bots – T-bot and Who-bot – start you on the platform, and enable you to search the company intranet and extract relevant information. Teams also features nearly 200 other integrations. Internal communication on Teams happens in group chat rooms with threaded conversations or via private chatting.

However, there are a few drawbacks. For small businesses on a budget, Teams doesn’t come cheap. Teams is also notoriously complex and time-consuming to set up, so you may need some patience.

Teams pricing: $4 per user/month for Business Essentials; $6 per user/month for Business Basic; $12.50 per user/month for Business Standard



Available on: Windows, macOS, iOS, Android, Web, Linux

While Fleep offers 20 or so integrations like Trello, Jira and Google Drive, you don’t get collaboration tools. Moreover, you don’t get native voice and video calling. That takes place through Whereby, which has its own limitations.

Fleep Pricing: Free trial for 2 weeks; Business plan starts at $5 user/month for full control over team communication and conversations; Enterprise plan requires a custom price offer

Flock offers the core chat features you’d expect from a business messenger software – chat channels, direct messages, group messages, threaded replies, and alerts and notifications.

Many IM tools require integrations for things like task management, to-dos, channel-based mailing and polls. With Flock, however, that’s all built-in. If you’re after integrations specifically, Flock offers over 50, with Google Drive, Trello, Dropbox, and Twitter, to name a few.

The free plan gets teams 5GB of shared storage, while Pro and Enterprise plans offer users 10GB and 20GB, respectively. You will face a strict file upload limit, though – just 100 MB.

Flock pricing: Freebie plan limited to 10K messages; $4.50 per user/month for Pro; Enterprise Plan on request


Available on: Windows, macOS, iOS, Android, Web

Ryver’s built-in Kanban board and task tracking keep everyone at work on the same page. Coupled with chat, voice and video communication, the messaging platform for business is worth considering.

Bear in mind, if your team relies on Zapier integrations, Ryver could be a huge hit to your bottom line. At $289/month for 50K tasks – Zapier plans aren’t cheap. What’s more, customization options are limited and there’s no free plan.

Despite falling behind Microsoft Teams, Slack is often lauded as the leading tool for business instant messaging and collaboration. That’s because Slack offers more integrations (1500+) than anyone and still has one of the biggest user-bases around.

With Slack, public and private channels, thread-based chat, and direct messages make it easy for organizations to streamline communications and have relevant conversations.

Screen sharing and voice and video are built-in, plus some nifty features like automated reminders and keyword alerts. The latter notifies you anytime a word of your choosing is mentioned. For the security-minded, Slack provides two-factor authentication, data encryption, enterprise key management and more.

However, Slack’s price point puts it out of reach for many startups and small teams. What’s more, its powerful integrations mean that many of its capabilities are the result of other tools and technologies, and they could expose your business network to vulnerabilities.

Luckily, there’s no shortage of other suitable IM programs. If Slack isn’t the tool for you, explore these 12 alternatives!

Slack pricing: Freemium version limited to 10 integrations; $7.25 per user/month Pro Plan; $12.50 per user/month Business Plan; Enterprise Grid on request

4 Common Communication Myths Debunked

Choose the Right Instant Messaging Platform for Your Business

Game of Instant Messengers

Instant messengers are in demand. The rapid growth of messaging apps as a preferred communication channel for billions, not to mention the enhanced security and productivity of business instant messengers, make IM technology a must have for any company.

But it’s not as simple as just choosing any messaging platform or program.

  • Use personal-grade IM apps as a way to connect with your customers, like handling quick product inquiries, for example. Be careful with apps that don’t offer end-to-end encryption as the default. Don’t use free instant messengers for internal team communication.
  • Go with a business instant messenger for your internal team communication and collaboration. Powerful security protocols, administrative control features, and productivity tools safeguard data and information while improving communication and teamwork.

When choosing the right messaging app for your business, examine your internal and external communication needs. That’ll help you determine whether an IM app might suit your business, or if an instant messenger for business, like Brosix, would be more appropriate.

Do people still use instant messaging?

Instant messaging is here to stay. In fact, instant messaging apps are one of the most prominent smartphone applications. WhatsApp, Facebook Messenger, and WeChat are the most popular instant messaging apps which total more than 4 million active users each month.

Is instant messenger private?

Compared to other forms of communication, IM is less secure because it uses a public network. Instant messaging conversations can be easily copied and pasted, which might lead them to fall into the wrong hands. There are further weaknesses related to authentication and passwords, which make it possible for information to reach the wrong people.

However, some instant messaging apps are more secure than others, which is why Brosix is one of the best options out there. Our solution is encrypted end-to-end on all communication channels, keeping communication private and worry-free.

What are the limitations of instant messaging?

Instant messaging is a limited form of communication because it relies only on written text. In-person communication allows you to read a person’s intentions and feelings through their body language and facial expressions. With instant messaging, it’s easier to misinterpret the intent of the message received.

Another limitation is related to its effectiveness in large groups. Instant messaging is a great tool for quick information transfers and casual conversation between two people or small groups. However, when numerous people are added to a single group chat, it can be difficult for everyone to follow the conversation.

What are the advantages and disadvantages of instant messaging?

Instant messaging comes with many advantages, the most prominent being that it facilitates short, focused conversations, enabling people to quickly share information. Instant messenger is more reliable than email and it grabs recipients’ attention more rapidly.

Another great plus of instant messaging is that it easily connects people regardless of their location. It’s especially helpful for people who work in hybrid or remote settings. Instant messenger apps are simple to use, intuitive and need very little tech knowledge.

On the other side of the coin, the most notable disadvantages of instant messaging are related to productivity and work distraction. While business instant messaging can help cut down needless time spent on ineffective communication, certain employees may waste hours each day on instant messenger.

What is the difference between instant messaging and texting?

The main difference between instant messaging and texting is that instant messaging doesn’t rely on the cellular phone service provided by the carrier to send messages.

Texting is possible on any mobile device, regardless of the cellular carrier, and no additional downloading is necessary. On the other hand, instant messaging requires the sender and receiver to download and use the same app to communicate.

Additionally, instant messenger allows sending multimedia content, such as images and videos, along with the text.

Another difference is related to international capabilities. While your international carrier plan determines the locations you can send texts and the cost involved, instant messaging apps make it possible for people to communicate regardless of their geographical location.

Is instant messaging safer than email?

Instant messaging and emails are both susceptible to malware. However, emails are more prone to malware and viruses. Although emails are often encrypted while in transit, they are typically stored unencrypted on the email server. Therefore email isn’t secure by default.

Instant messaging apps are built with security and privacy in mind, therefore end-to-end encryption makes instant messenger safer than email to some extent.
