Top 4 Best Messengers for Business in 2025!

Essential features of a business communication app
In the case of corporate messaging apps, several features are universally essential, and I kept them in mind when reviewing them. Choosing the best messenger is not as easy as it may seem, so this list may prove useful because it helps you determine the most important features it should have.

Organization of conversations
Some messages need to be visible to the entire company, while others need to be visible to a specific team. The best chat app for work organizes conversations in a transparent way, allowing users to decide what they see and what they don’t. This means that team members can join channels based on whether they’re relevant or not. Ideally, conversations can be broken down even further using threads or similar features to prevent employees from talking over each other. The ability to tag people and bring them into conversations they might otherwise miss is also a must.

Universal search capability with filtering features
There’s nothing more frustrating than having the same conversation multiple times, which is why search is essential. When it comes to work chat, your team should be able to quickly search through past conversations for relevant information. Filtering features make this much easier, giving you access to conversations from months ago.

Audio and video chat capability
Some conversations are best done out loud. The best team chat apps should offer voice and video communication, as well as the ability for users to share their screens for collaboration.

Easy to navigate
Members must be able to quickly navigate through different conversations. User interfaces must be clean, without unnecessary elements. There should be appropriate keyboard shortcuts, mobile gestures, and other ways to quickly move from channel to channel in business communication apps.

Sharing files, photos, links, source code
You’re here to work, and the ideal business communication app should make it easy with features designed for team collaboration. Sharing files should be as easy as clicking and dragging. Links should have built-in previews.

Possibilities of personalization and adding your own functionalities
It is no secret that each company has its own needs regarding the functions of an application for communication between employees, so it is good for it to have room for implementing independently developed functionalities.

Status modification
When working remotely, we don't sit in front of a computer for the full eight hours, so it's good to be able to change your status in the messenger so that your colleagues know what you're currently doing and what the delay in replying is. You can also use this function to indicate that you're on vacation, for example, so that no one will disturb you.

Best Messengers for Business
Here's our pick of the best business communication apps

1.SLACK
Slack launched in 2013 and quickly dominated the office chat space, in no small part because people loved using it. It’s easy to see why—it’s an app designed with the user and their team in mind.

Each Slack team has a general channel for the entire company, but most day-to-day conversations happen in channels related to a specific team or project. Users decide which of these channels they want to be in, which means they can avoid being flooded with messages about projects unrelated to them.

Great message sorting goes a lot further, as conversations in these channels can be threaded, and users will only be notified of threaded conversations if they participate or actively choose to subscribe to them. Team members can tag other users to bring them into channels or threads, which helps balance the need to reduce clutter with the need to ensure that important conversations are visible.

Slack also makes it easy for users to find answers through search. You can easily filter by channel, user, date, and more.

Making collaboration easy is another key element. Messenger lets you quickly share important files by simply dragging them into the app. Most links will expand into a quick preview, meaning things like images and videos can be viewed without leaving the app. Little features like emoji reactions make it easy to respond to messages in a few clicks, and video and audio calls can be started singapore telemarketing data with a single click. Slack also offers thousands of integrations with other apps. All of these little things can seem overwhelming, but the clever design (along with friendly text in every corner of the app) means that Slack rarely feels confusing or overwhelming.

Slack’s main downside may be its price — especially considering it’s not part of a larger software suite. For teams that are serious about workplace chat, however, Slack offers enough value to make it worthwhile.

It should also be emphasized here that its major disadvantage is the fact that in the free plan, messages are archived after 90 days, which means you lose access to them - so if you want to find a message from 3 months ago, you need to buy a paid package.

Slack Pricing:
It is divided into several levels.

Free:
messages disappear after 3 months,
10 Apps You Can Access From Slack
1:1 audio and video meetings,
exchanging messages with a person outside the organization 1:1,
1 workspace, which is where all your news and channels live.
Pro ($8.75/mo/user):
messages don't disappear,
no restrictions on applications with Slack access,
group audio and video meetings,
the ability to exchange group messages with people outside the organization,
1 workspace, which is where all the news and channels are,
unlimited workflow, i.e. the ability to automate routine tasks or processes within the application,
the ability to co-create documents and other files on Slack templates in real time,
AI-powered features such as intelligent news search.
Business + ($15/month/user):
has all the same features as in PRO, plus:
automatic user management (adding or removing users when they leave the company, as well as updating information about them),
the ability to log in to Slack using a selected account from (IDP), so employees do not need to have separate login details,
ability to export data from all channels and conversations.
Finally, it is worth adding that there is another package, called Enterprise Grid, but its pricing requires individual contact with the sales department . It offers (in addition to all options such as the Business + plan):

data backups to avoid data loss,
Possibility of configuration with HIPAA, which allows to ensure security in terms of protected data,
a built-in employee directory where you can browse information about them and search for them by keyword.
In the case of Slack, you can choose to either pay monthly or (for a more affordable price) subscribe annually.


2. MICROSOFT TEAMS
Another great program that caught my attention is Microsoft Teams.

Each Microsoft Teams account is associated with a single organization, which represents the entire company. Users are invited to join one or more teams within the company, and each team is divided into channels, and conversations in those channels are organized into threads. Teams has the most layers of organization of any business chat app I’ve tested.

MS Teams users have the ability to schedule meetings, with an agenda, and spontaneous calls. There are also extensive collaboration features, including tight integration with Microsoft Office, which allows collaboration on documents, calendar appointments and notes, which is a huge advantage.

The main downside to Teams is how much work it requires to implement . If you don’t have a dedicated IT staff, it’s going to be a pain to set up, especially if you’re trying to set up the free version. But considering the size of organizations that Teams seems to be aimed at, that’s probably not too much of a hurdle — especially if your team is already using Microsoft’s suite of apps.

The MS Teams price list, similarly to Slack, is divided into several packages:
Microsoft Teams Essentials (€3.70 per month/user):
each user has 10 GB of cloud storage,
real-time collaboration, file sharing,
the option of recording meetings with transcripts and live subtitles in English,
data encryption for meetings, chats, files and calls.
Microsoft 365 Business Basic (€5.60 per month/user):
in addition to what is available in the lower package, it also offers:
24h technical support,
ability to manage identity, access and users for up to 300 people,
business e-mail (you@your_company.com),
both web and even mobile versions of Word, Excel, PowerPoint and Outlook,
up to 1 TB of cloud storage capacity for each employee,
automatic spam filtering,
over 10 additional cloud applications useful for every business (Word, Excel, PowerPoint).
