Most businesses know they need to communicate effectively externally to make sales. Fewer realise that applying the same mindset internally also increases profitability.
Internal and external communications are two different disciplines: same company, same values, but very different audiences, purposes, and approaches. Confusing, ignoring, or treating them the same is more costly than most realise.
According to the USC Annenberg School for Communication and Journalism and Staffbase’s 2024 Employee Communication Impact Report, 71% of employees are unsatisfied with the quality of internal communications they receive. Meanwhile, Edelman’s 2024 Trust Barometer found that brand trust has become a “buy or boycott” factor for 71% of global consumers.
Two audiences. Two crises that impact the bottom line. Both are coming from the same root problem: confusion.
Let’s start simple, because this is where most people trip up.
The channels, approach, and level of detail are different. Critically, the relationship is different. Your team already has context; they are on the bus and believe in what you are doing (well, you hope). Your customers do not. Your team needs honesty, even when things are messy.
Your customers need confidence, even when things are complicated.
It’s worth being specific because internal comms are often reduced to “the internal newsletter” or “the all-staff update”.
In reality, it touches almost every part of how a business operates.
The job advert, interview tone, and offer email are all internal communications in disguise. They show candidates what working for you actually feels like before they sign anything. According to Gallup, organisations often fail to deliver on recruitment promises, and that gap between expectation and reality drives early disengagement.
Gallup found only 12% of employees strongly agree their organisation does a great job onboarding new people. This is not just a culture problem; it is a commercial one that costs you in the long run. Poor onboarding drives early exits, which are expensive to replace.
Even if they don’t feel like it! How you write a holiday request process, disciplinary policy, or flexible working guide sends a clear signal about how the business views its people. Dry, legalistic language communicates distance. Clear, human language communicates respect.
The CIPD notes that effective employee voice requires complementary channels supported by leaders, and people professionals must embed communication into the organisation’s culture and practices. It is not a “here is the policy” and done situation; policies need to be understood at a human level and communicated through words and actions.
Regular check-ins between managers and direct reports are among the most powerful and underused internal communication tools. Research from ADP’s Marcus Buckingham Company found employee engagement improved by 57% when team leaders held frequent one-to-ones. Weekly is the recommended frequency – not monthly, quarterly, or “when there’s something to discuss.”
They don’t need a formal agenda; a simple two-way conversation about work progress and needs can go a long way.
External comms is where most marketers feel most comfortable, and for good reason. It’s more visible. It has clearer metrics. But it comes with its own discipline.
Your blog post, social media activity, email campaigns, website and press releases are all speaking to someone who doesn’t have the inside track. They need to understand who you are, why it matters, and why they should trust you, often in seconds. The goal is to earn attention, build credibility, and move people closer to a decision.
So while the goals are different, internal communications create alignment, clarity, and a sense of belonging. External communications creates trust, visibility, and conversion. Both require intentional thinking about audience, tone, and purpose relevant to the right channel before any action takes place.
This is where it gets commercial, so strap in.
Most businesses focus their communication energy externally because it is easier to measure ROI. Internal communications is often under-resourced, under-planned, or handed to whoever has a spare hour. That imbalance has a real price tag.
Axios HQ’s State of Internal Communications Report found a single employee earning £40,000 to £80,000 loses the equivalent of 35 working days per year due to ineffective internal communication. Multiply that across a team, and the numbers get uncomfortable quickly. The same report found 80% of leaders believe their internal communications are clear and engaging, but only 50% of employees agree.
That gap matters because when employees don’t understand what’s happening, they disengage. Disengaged employees not only underperform internally but also affect the customer experience. The Staffbase 2024 report found 24% of employees say their company’s communication problems directly led to a poor customer experience, and 14% reported their company losing customers as a result.
Internal confusion becomes external damage every time.
On the external side, the cost of poor communication is equally measurable. Edelman’s 2024 research found that 71% of consumers now consider trust a deciding factor in whether they buy from a brand at all. When external messaging is inconsistent, unclear, or contradicts the reality of the business, that trust erodes fast.
Starbucks’ 2024 PR difficulties illustrate exactly this: the failure to align internal culture with external messaging meant that carefully crafted public statements rang hollow when they didn’t reflect how the business actually operated day-to-day. The external promise and the internal reality were telling two different stories.
The real damage isn’t just having weak communications in one area. It’s when the two are actively pulling in different directions. Research from Madison Taylor Marketing found that aligned companies see up to 19% faster revenue growth and a 15% increase in profits compared to those that aren’t.
The 2024 Global State of Internal Communications Report found that despite 80% of organisations recognising the value of internal communication, 53% had no defined internal communication plan. No plan means no consistency. And no consistency means the gap between what people experience inside and outside the business keeps widening, often quietly, until something has to give.
Many in-house marketers manage both internal and external communications, often without realising the two require different approaches. You might write a LinkedIn post and an all-staff update in the same afternoon, and the lines blur. Internal communications may originate from HR but if you’re the one sharing them, you need to ensure what you’re sending out is consistent.
Here’s a practical breakdown of what each entails day to day.
The audience shapes everything. Before you write anything, ask: Is this for someone who already works here, or someone who doesn’t know us yet? That single question changes the level of context you include, the formality of your tone, the call to action, and what success looks like.
Brand voice versus tone of voice. Your brand voice is your personality; it stays consistent. Your tone is how that personality shows up in different situations and should adapt. A Slack message to your team doesn’t need to sound like a press release. But both should be recognisably the same brand. People engaging with your brand could become employees one day. You don’t want them to experience whiplash when they get a completely different employee experience than the one they had externally. That’s when trust starts to erode.
Employees are your most credible external communicators. The Staffbase 2024 report found that employees who receive sufficient information from their employer are 35% more likely to stay in their jobs for the next year. People who feel informed, valued, and aligned with the business show up differently in their work, in their conversations with customers, and in what they say about you publicly.
Don’t underestimate small touchpoints. Every recruitment ad, every process that hasn’t been ironed out, every policy document, every one-to-one cancelled without explanation are internal communication signals. They shape how your people feel about the business, and that feeling shows up in everything they produce externally.
It doesn’t have to be a lengthy exercise, but it gives you a reference point that both internal and external communications can come back to.
Same values, same pillars, different applications depending on the audience. We cover exactly how to do this in our Message House module in the Better Content Club.
When people help shape how the business communicates and operates, they are far more likely to champion it. The CIPD describes this as the difference between consultation and participation. When employees know their input will directly influence the outcome, they feel greater ownership and mutual accountability.
Co-creation doesn’t have to be complex. It can be as simple as asking your customer service team to review your next client communication before it goes out, or involving a cross-section of colleagues when you’re updating a policy. The goal is to make people feel like contributors, not just recipients. That shift in ownership tends to show up in how carefully they then represent the brand externally.
Measuring internal sentiment gives you a baseline and helps focus your energy. You cannot fix what you do not know is broken, and without regular checks, it is easy to assume your internal communications are landing when they are not. Evidence suggests most leaders overestimate this. Axios HQ’s 2024 State of Internal Communications found only 14% of employees feel entirely aligned with their organisation’s goals. Among those who do, 75% say communications from leadership are effective. That shows a direct link between communication quality and alignment.
Many tools exist, like Workleap, but a short, anonymous pulse survey sent quarterly could start building trust and show you take action. That matters. When employees see their feedback influences something, trust compounds. When they do not, the survey becomes noise.
The businesses that get this right are not necessarily the ones with the biggest teams or budgets. They understand that internal communications build culture, while external communications build trust.
When these two are out of sync, people notice, and it costs everyone. Get them aligned, and everything else will fall into place.
