By: Nobody got into internal communications because they love spreadsheets.
But here's the thing. If you can't show what's working and what isn't, leadership will eventually ask why they're paying for it. And "people seem engaged" isn't an answer that survives budget season.
The good news is you don't need a data science degree. You need five or six numbers, some context for what those numbers mean, and a simple way to present them. The analytics aren't complicated. The hard part is knowing which numbers matter and which ones just look nice on a slide.
Why Measuring Internal Comms Is Difficult
Most teams struggle with measurement for one basic reason: the tools weren't built for it.
Email tells you opens and clicks. That's about it. You know 340 people opened Tuesday's newsletter. You have no idea if they read it, which parts they cared about, or whether they closed it after two seconds.
Intranets give you page views. Again, surface-level. Someone visited the page. Maybe they read it. Maybe their browser auto-loaded it in a tab they never looked at.
Surveys ask employees how they feel about communication. Those responses are useful but lagging. By the time you get survey results, the communication already happened weeks ago. You're measuring memory, not engagement.
Gallagher's State of the Sector report found that while 74% of internal communicators say measuring effectiveness is a top priority, the majority don't feel confident in their measurement approach. That gap exists because the standard tools weren't designed to measure content engagement.
So what do you actually track?
The Metrics That Matter
1. View Rate (Reach)
The most basic question: did people open it?
View rate is total unique opens divided by total recipients. If you sent an update to 1,000 employees and 620 opened it, your view rate is 62%.
Benchmarks: According to PoliteMail's analysis of 4.8 billion internal emails, the average internal email open rate is 64%. Companies with fewer than 1,000 employees tend to hit 80% or higher. Large enterprises with 10,000+ employees often drop below 50%.
View rate tells you whether your distribution is working. Low view rate? Your subject lines are weak, your send time is off, or people have stopped expecting anything worth reading from you.
But high view rate alone means almost nothing. Someone opening a document for three seconds and someone reading every page both count as one view. You need the next metric.
2. Time Spent (Depth)
How long did people actually engage with your content?
This is where things get real. A 10-page company update should take 4-6 minutes to read properly. If your average is 45 seconds, people opened it, glanced, and left. If your average is 5 minutes, they actually read.
Benchmarks: There's no universal standard here because it depends on content length. The simple formula: divide expected reading time by actual average time. If expected is 5 minutes and actual is 4 minutes, that's solid. If expected is 5 minutes and actual is 1 minute, you've got a scanning problem.
Time spent also helps you spot differences between audiences. Maybe the marketing team spends 6 minutes and the engineering team spends 30 seconds. That tells you your content resonates with one group and not the other.
3. Completion Rate (The Real One)
What percentage of readers made it to the last page?
This is the metric that separates "people saw it" from "people read it." An open with no completion is like a meeting invitation that gets accepted but nobody shows up.
Benchmarks: For short updates under 5 pages, aim for 60-70% completion. For longer documents of 10-20 pages, 40-50% is reasonable. Below 25% on anything means the content isn't holding attention past the first few pages.
Completion rate is especially critical for compliance communications. If you need employees to read the new harassment policy and only 30% finished it, that's a documentation gap and a liability.
4. Page-Level Engagement (Where They Stop)
Which pages get attention and which get skipped?
This is where you learn what employees actually care about. If page 3 about the new benefits plan gets 90% of readers but page 7 about the executive offsite gets 20%, that's direct feedback on content priorities.
Page-level data also shows you where you're losing people. If there's a consistent drop-off at page 4, something about page 4 is killing momentum. Maybe it's too text-heavy. Maybe the topic isn't relevant. Maybe it's just the natural attention limit for your audience.
5. Trend Over Time (Direction)
Are your numbers getting better or worse?
Any single data point is just a snapshot. The real story is in the trend. If your completion rate was 55% three months ago and it's 42% now, something changed. Maybe your content got longer. Maybe people are busier. Maybe you changed formats.
Track your core metrics monthly and look at the 3-month and 6-month trends. Improving trends mean your approach is working. Declining trends mean something needs to change before leadership notices.
What Not to Track
Some metrics feel important but don't actually help you make better decisions.
Device type matters less than you think. Knowing 40% read on mobile is mildly interesting. It doesn't change what you do unless you're not mobile-friendly, in which case the fix is obvious.
Geographic breakdown is usually noise for internal comms. Unless you're specifically trying to reach a particular office or region, knowing that the London office has higher engagement than the Austin office doesn't lead to useful action.
Individual names for routine communications. Tracking who read the weekly update by name feels like surveillance and creates trust problems. Save individual tracking for critical items like policy acknowledgments and compliance training where accountability is actually required.
How Do You Report This to Leadership?
Executives don't want a data dump. They want three things: are people receiving our communications, are they reading them, and what should we do differently?
The Monthly Report
Keep it to one page. Seriously. One page.
Section 1: The headline number. "68% of employees read the February company update to completion." That's your lead. One sentence that tells the story.
Section 2: Comparison. "Up from 61% in January. The shorter format and visual layout drove higher engagement." Context makes the number meaningful.
Section 3: What worked. "The benefits enrollment reminder had the highest page engagement at 94% completion. The leadership Q&A section saw a 15% increase in time spent compared to last month."
Section 4: What needs attention. "Three departments had completion rates below 40%. We're testing targeted follow-ups for March."
That's it. Four short sections. Takes leadership two minutes to read and gives them everything they need.
The Quarterly Review
This is where trends matter. Show the trajectory.
A simple line chart of completion rate over three months tells a story faster than any paragraph. If the line goes up, your strategy is working. If it goes down, you need to explain why and what you're changing.
Compare quarters against each other. "Q1 averaged 58% completion versus Q4's 51%." Then explain the difference. Did you change formats? Shorten content? Switch send days?
The metrics you present to leadership shape what they'll ask you to optimize. Measure the wrong things and you'll get very good at improving the wrong things. Choose them carefully.
Tying Metrics to Business Outcomes
This is what makes leadership actually care.
"62% completion rate" is an internal comms metric. "62% of employees read the safety protocol update, up from 44% before we changed formats, and safety incidents dropped 18% in the same quarter" is a business metric.
Jenni Field, who founded the consultancy Redefining Communications, says it with less patience than we just did: "Stop counting emails sent and intranet page views. Start measuring business outcomes."
Connect your communication data to outcomes whenever possible. Benefits enrollment completion. Policy acknowledgment rates. Training compliance numbers. These connections turn internal comms from a cost center into a risk management function.
What Tools Do You Need?
You can't measure what you can't track. And you can't track much with just email.
At minimum, you need a content platform that gives you page-level analytics. Something that tells you not just who opened, but how long they spent and how far they got. Flipbook platforms do this naturally because each page is a trackable event.
The internal communications workflow looks like this: create the content, publish it as a trackable document, send the link via email, and check the analytics afterward. The email gets the click. The document gets the data.
Some teams try to build measurement into their existing email tools. It works to a point. You'll get opens and clicks. But you won't get time spent, page engagement, or completion rate. And those are the numbers that tell you whether communication actually happened.
Start Simple, Get Better
You don't need all of this on day one.
Start with view rate and completion rate. Just those two numbers, tracked monthly, will tell you more about your internal communications than most teams have ever known.
Once you're comfortable with those, add time spent and page-level engagement. Then start building the monthly report for leadership.
The goal isn't perfect measurement. The goal is knowing enough to make better decisions about what you communicate, how you format it, and when you send it.
Most internal comms teams operate on intuition and hope. Even basic metrics put you ahead of that. And when budget conversations happen, you'll have numbers instead of feelings.
FAQs
What's the most important internal communications metric?
Completion rate. It tells you who actually consumed the full message, not just who clicked. Opens measure delivery. Completion measures communication.
How do I measure internal comms if we only use email?
Email gives you open rates and click rates, but nothing deeper. To measure actual engagement, you need content that tracks page views, time spent, and completion. A flipbook with analytics does this automatically.
What's a good benchmark for internal email open rates?
PoliteMail's benchmark data shows the average internal email open rate at 64%. Companies under 1,000 employees often exceed 80%. If you're consistently below 50%, your subject lines or send times need work.
How often should I report internal comms metrics to leadership?
Monthly for regular updates, quarterly for trend analysis. If there's a critical communication like a policy change or benefits deadline, report on that specific piece within a week of sending.
Can I track internal communications without being invasive?
Yes. Aggregate data like overall completion rates and average time spent tells you what's working without singling out individuals. Use individual tracking only for critical compliance communications where accountability is required.
