Internal communication tools: main types and how to choose

By Nicolas Saliba · Updated October 2026 · 10 min read

In short

Internal communication tools fall into a few types: intranets, employee apps, enterprise social networks, chat, email, video and events, in-person channels, and listening tools. Do not choose from a ranked list. Decide which jobs your channel mix has to cover, check what Microsoft 365 already covers, add a specialised platform only for a job nothing else does well, and give every channel one metric you review by audience.

Key takeaways

In Gallagher’s Employee Communications Report 2026, based on more than 1,300 communications and HR professionals, only 1 in 4 organisations have a channel framework.

Teams with an active channel framework reported a 29% boost in channel capability, according to the same report.

Microsoft positions Viva Engage as the social fabric and Viva Connections as the gateway; Viva Amplify publishes one campaign to Outlook, Teams and SharePoint.

Tryane’s Digital Workplace Benchmark 2026 calls Staffbase, Poppulo and Firstup specialised internal communication tools, and scores Analytics at 92% for Poppulo against 45% for SharePoint.

Gallagher found a 37% increase in overall channel effectiveness between teams with low and high data measurement capability.

What are internal communication tools, and what types exist?

Internal communication tools are the software and channels an organisation uses to inform employees, hear from them and help them talk to each other. Most published lists rank ten or fifteen products side by side, mixing chat apps, intranets, survey tools and recognition platforms as if they competed. They do not. A chat tool and an intranet do different jobs, and the useful question is which jobs your organisation needs covered, not which brand comes first.

Here are the main types, the job each one does and what it is usually measured by.

Type	Main job	Microsoft 365 option	Other examples	Measure it by
Intranet and news	A durable place where official information and news live	SharePoint home site, communication sites and news	Unily, LumApps, Powell 365, Simpplr	Share of each audience reading key news
Employee app and multichannel platform	Push targeted news to people, including those without a desk	SharePoint app in Teams (formerly Viva Connections), Viva Amplify	Staffbase, Poppulo, Firstup, Workvivo	Reach by audience, including deskless groups
Enterprise social network	Conversations and communities where replies are expected	Viva Engage	Workvivo	Active participants and replies per post
Chat and team collaboration	Day-to-day work in teams and projects	Microsoft Teams	Slack	Use of designated announcement channels
Email	Reach people who do not come looking	Outlook, Viva Amplify	Email newsletter tools	Reach and read rate by audience
Video and events	Leadership town halls and live Q&A	Teams town hall, Viva Engage events	Video platforms	Live and replay attendance by audience
In-person and manager channels	Context and dialogue that digital cannot carry	Manager briefing packs on SharePoint	Team meetings, site briefings, signage	Cascade completion; mark as estimated
Listening	Feedback, pulse surveys and focus groups	Microsoft Forms, Viva Engage questions	Survey and pulse tools	Response rate and action taken

The platform examples come from the 12 platforms scored in Tryane’s Digital Workplace Benchmark 2026 and from common categories; they are illustrations, not a ranking. One tool can cover several rows, and that is the point of thinking in jobs: two tools doing the same job for the same audience is a cost, and a job no tool covers is a gap.

Which jobs must your channel mix cover?

Start from jobs, not tools. Gallagher’s Employee Communications Report 2026, based on a survey, roundtables and focus groups with more than 1,300 communications and HR professionals between September and November 2025, found that only 1 in 4 organisations have a channel framework. Those with an active channel framework reported a 29% boost in channel capability, meaning channels that are fit for purpose.^[1] A channel framework does not need to be long. It needs to say, for each job, which channel does it, who owns it and how you will know it works.

Five jobs cover most organisations:

A durable home for information. Policies, news and resources people can find again. Without it, questions get answered by rumour.
A place where replies are expected. Communities or channels where employees can ask, comment and challenge. Without it, leaders broadcast and never learn what landed badly.
A push that reaches people who do not come looking. Email, notifications or an app. Without it, only the already engaged see anything.
Reach without a desk or a corporate device. Managers, shared devices, signage, printed boards. Without it, whole populations are structurally invisible.
Listening. Surveys, focus groups and comment analysis. Without it, the team measures its own output and calls it impact.

Two findings from the Gallagher report should shape how you weigh these jobs. First, demand for in-person channels has increased: in frontline-heavy environments, respondents rated in-person town halls as their single most effective channel (51%), and that rating drops 18 points when the town hall goes virtual. Second, line managers remain one of the most relied-upon channels, especially for frontline and distributed workforces, but their effectiveness is inconsistent because most organisations treat them as one uniform channel without consistent support.^[1] No software replaces those two channels; the right tools support them. Our note on measuring frontline worker communications covers what can be counted for those populations.

Which Microsoft 365 tools already cover these jobs?

If your organisation runs on Microsoft 365, map what you already own before you look at anything else. Most of the jobs are covered at least partly.

SharePoint home site and news cover the durable home. A SharePoint home site is a communication site that searches the whole intranet, and news published from it automatically becomes official organisational news and takes priority on the SharePoint start page.^[2]
Viva Engage covers conversation. Microsoft describes Viva Engage as the social fabric for Viva and Microsoft 365, where people ask questions, share knowledge and extend their network, and Viva Connections as the gateway where people start their workday and catch up with news, tasks and resources.^[3]
Outlook and Viva Amplify cover the push. Viva Amplify lets communicators manage campaigns in one place, publish to several channels at once and track how messages are received.^[4] Microsoft lists Outlook, Microsoft Teams and SharePoint as its publishing channels.^[5] It is a web experience enabled for users licensed for Microsoft Viva or Viva Employee Communications and Communities, among other plans, so check your licences before you plan around it.^[6]
Microsoft Teams covers team collaboration and, through Teams town hall, large live events. Designate one announcement channel per audience rather than letting news scatter across chats.

What Microsoft 365 covers least well is usually the fourth job, reaching people without a desk or a corporate account, and the measurement that runs across all of them. Those are the gaps worth buying against. For a deeper view of how Viva Engage fits next to the other channels, see Viva Engage in the internal communication mix.

When is a specialised IC platform worth adding?

Specialised internal communication platforms exist because SharePoint and Teams were built for collaboration first. Tryane’s Digital Workplace Benchmark 2026 scored 12 intranet and employee communication platforms based on demos, expert interviews and public data. It describes Staffbase, Poppulo and Firstup as specialised internal communication tools with an intuitive user experience, and SharePoint as a must-have platform that requires customisation to be truly effective for internal communication. The category scores show where the difference lies: Analytics scored 92% for Poppulo against 45% for SharePoint, and Targeting 95% for Firstup against 72% for SharePoint. Workvivo is described as mobile-first and particularly strong for frontline engagement. Download the full Digital Workplace Benchmark 2026 to compare all 12 platforms criterion by criterion.

A specialised platform is usually worth it when at least one of these is true:

A large part of your workforce has no corporate email or desk, and managers and signage are not enough to reach them.
You need to target the same message to many audiences, by role, site and language, and your Microsoft 365 groups cannot support it.
Several teams publish to the same employees and you need one place to plan, approve and schedule.

Before you sign, answer six questions in writing, because a vendor cannot answer most of them for you.

Which job is unowned, and is a tool the answer? Often the gap is a person or a cadence, not a product.
Who publishes, how often, and what happens when they leave? A channel that goes quiet for two months teaches people not to look.
What audience model does it use? If it keeps its own recipient lists, you have a second version of the organisation. Attributes should come from Microsoft Entra ID or an HR extract so that percentages across tools share a base. See audience segmentation for internal communications.
What does it retain, and can you export it? Ask for the retention window and export format before signing.
Does it create a second source of truth? Two places holding the same announcement produce two versions.
What is the exit? What happens to three years of history when the tool is replaced, and does your year-on-year comparison survive?

When should you drop a tool instead of adding one?

Three signals point to subtraction. A channel with no named owner and no cadence should be closed rather than relaunched. Two channels serving the same audience with the same content should become one, with the other pointing to it. And a tool whose only remaining use is one annual campaign is a licence you pay to keep a habit alive.

Consolidation is unglamorous, and it is often the move with the highest return for a team in its second or third year of building its channel mix. Where your function sits on that curve is worth checking against our internal communications maturity model before the next budget cycle.

How do you measure what each channel delivers?

Every channel you add brings its own reporting: the intranet reports views, email reports opens, Viva Engage reports active members, and signage reports nothing. None of these numbers can be added, and the same person appearing in three of them looks like three people. Gallagher found that fewer than 1 in 5 respondents are satisfied with their ability to personalise communication to their audience. It also found a 37% increase in overall channel effectiveness between teams with low and high data measurement capability, and the high scorers were 3 times as likely to be satisfied with their channels’ reach and personalisation.^[1]

Give each channel one primary metric, and read every metric by the same audiences: department, country, role and site, against headcount.

Channel	One primary metric	Read it by
Intranet news	Share of the target audience that read the post	Department and country
Email	Share of recipients who opened and read, not only delivered	Department and country
Viva Engage	Share of members who reacted or replied	Community and department
Campaigns across channels	Unique people reached across all channels	Target audience
Town halls	Live plus replay attendance	Site and role
Manager cascade	Share of managers who confirmed the briefing (estimated)	Site

Channel reports such as Viva Amplify’s show how one campaign was received in each channel.^[4] The harder question is the one leadership asks: what share of the workforce saw the announcement, on any channel, compared with last quarter. Answering it means counting people rather than events, across channels, against a workforce denominator. The method is in measuring cross-channel internal communications.

That is the job Communication Insights does for Microsoft 365: it brings SharePoint, Viva Engage, Viva Connections and email newsletters into one place and joins them to your organisational structure, so you can compare channels by audience and decide which to keep, change or drop. It is not another channel. To see every channel measured in one view, book a 15-minute call with Jérémy.

Frequently asked questions

What are the main types of internal communication tools?

Intranets and news sites, employee apps and multichannel platforms, enterprise social networks, chat and collaboration tools, email, video and event tools, in-person and manager channels, and listening tools such as surveys. One tool can cover several types; a channel framework assigns each job to one primary channel.

Do we need a dedicated internal communication platform on top of Microsoft 365?

Often not. Most organisations on Microsoft 365 already own a publishing surface, a conversation surface and a push channel. A specialised platform makes sense when you must reach many employees without a desk or corporate email, or need targeting and orchestration your Microsoft 365 groups cannot support.

How many channels should an internal communication team run?

Fewer than most run. Each channel should have a named owner, a stated cadence and an audience it reaches better than any other channel. Channels that fail all three are usually kept out of habit and should be closed or merged.

Is Viva Amplify still available?

Yes. Microsoft’s set-up documentation, updated in May 2026, describes Viva Amplify as a web experience enabled for users licensed for Microsoft Viva, Viva Employee Communications and Communities and some other plans. It manages campaigns and publishes to Outlook, Teams and SharePoint.

Should signage and print count as channels we measure?

Plan them as channels and report them honestly as estimated rather than measured. A screen in a canteen has real reach and no telemetry worth trusting, so mark it as an estimate instead of folding a guess into a total.

How do we compare tools that report different metrics?

Choose one primary metric per channel and read every metric against the same audience base, such as department and country headcount from Microsoft Entra ID or an HR file. Then count unique people reached across channels, not the sum of each tool’s views.
