Beyond open rates: The internal newsletter metrics that matter
TL;DR: True internal newsletter success isn’t measured by opens or clicks—it’s measured by whether employees understand, act and change behavior in ways that influence business outcomes.
Newsletter performance is often measured in numbers: open rates, click-through rates and read time. These metrics are useful in tracking how employees are engaging with a specific channel, but they fall short in answering the question leadership really cares about: did anything change?
If you’re only measuring channel engagement, you’re not measuring impact. To create a truly effective internal comms system, you need to measure success by what happens after the email is read.
Did employees understand the message? Did they act on it? Did it change how they work? Asking these questions (and using them to determine success) shifts your internal newsletter from a megaphone that reaches the most people possible to a strategic business lever that drives employee behavior. Here’s how to do it.
What newsletter metrics tell you (and what they don’t)
Quantitative newsletter metrics are useful for understanding channel performance. But to use them effectively, you need to understand what they can and can’t tell you.
Open rates = Reach signal
Open rates tell you whether employees are seeing your message. Employees are more likely to open your email if you’ve repeatedly demonstrated that these messages are valuable to their work.
High open rates are indicative of strong subject lines, familiarity with the sender and effective timing.
What open rates don’t tell you is how your message was experienced. Was the content understood? Was it relevant? Did it change anything?
Click-through rates = Action signal (when relevant)
If your newsletter has a clear call to action, click-through rates show that employees were motivated to take the next step.
But clicking a link doesn’t point to follow through. Click-through rate doesn’t tell if the action was completed or if the message influenced outcomes—two frequent and key goals of internal newsletters.
Open rates = Mixed signals (Use with caution)
Your email platform might display read time alongside open and click-through rates, but it can be tricky to interpret as a measure of success.
For example, a short read time could mean a message was clear, or it could mean readers don’t care—the message isn’t grabbing their attention. Long read times could indicate employee interest, or that the information was tough to process or understand.
At bink, we usually advise clients to avoid using read time as a channel performance measure. To us, there are too many caveats to consider.
The strategic shift: From channel metrics to performance signals
The most effective internal comms teams don’t end their analysis at open and click-through rates. They go beyond channel metrics to identify the performance signals that indicate their message was heard and acted upon.
Channel metrics measure what happened inside the communication.
Performance signals measure what happened because of it. Channel metrics can help influence performance signals.
What does this look like in practice? Let’s say your team is running a safety campaign. Your weekly newsletter featured articles or interviews on safety, there was a segment in your Town Hall and managers discussed the new policy with teams.
When you’re building a report to capture the success of the campaign, include:
- The “inputs”: the newsletter, the segment, manager discussions
- Any associated channel metrics: open rates and/or click-through rates
- Performance signals: The reduction in safety incidents, or an increase in the number of “Good catch” reports of potential safety violations
By going beyond the vanity metrics and bringing in the performance signals, you’re showing how your team is driving clarity, alignment and real outcomes.
The benchmarking trap
When teams struggle to quantify success, they often look at external benchmarks. But benchmarks lack the context that the best internal comms teams navigate every day. Team size, audience type, channel ecosystem and industry can sway metrics from organization to organization.
Instead of benchmarking against other companies, benchmark against your own organization. Take a look at similar audiences (like teams or regions) and compare newsletter performance and impact among them.
What patterns show up? What drives success in each context? How can you use these learnings to influence other teams and outcomes?
This practice creates benchmarks that drive relevant action, not just reference points.
When industry benchmarks do matter
Industry benchmarks still have value when used strategically. When presented to leadership, they can help build a business case for additional resources or demonstrate what “best-in-class” organizations are doing differently. The key is to use benchmarks as inputs, not conclusions. They shouldn’t be the end-all be-all.
The real goal: Clarity, alignment and action
When done well, internal newsletters can help clarify priorities, align teams and drive action.
As an internal comms leader, you do more than get a message to the most people possible; you influence employee behavior for the strength of culture and performance.
When communication drives behavior—not just engagement—it becomes a true performance lever. And it starts with how you optimize and measure success.
FAQ: Internal newsletter metrics
What is a good internal newsletter open rate?
There’s no universal benchmark. Open rates vary widely based on audience, channel, and context. A “good” open rate is one that improves over time within your own organization and aligns with your communication goals.
Why are open rates not a reliable success metric?
Open rates only measure whether an email was opened—not whether it was read, understood, or acted on. They reflect reach, not effectiveness.
What metrics should internal communications teams track?
Teams should track a mix of signals, including reach (open rate) and action (click-through rate), alongside performance indicators like behavior change and alignment.
How do you measure communication effectiveness?
Effective measurement connects communication to outcomes. This includes whether employees understand priorities, take the right actions, and experience less confusion in their work.
Should you benchmark newsletter performance?
Yes, but with context. Internal benchmarks (by role, region, or function) are more actionable than external comparisons. Industry benchmarks are best used for strategic decisions, not day-to-day evaluation.
