Why You Should Be Using a Casual Tone in Customer Service

Using the Right Tone: What Louis C.K. Can Teach Us About Customer Service

In customer service, what you say doesn’t matter nearly as much as what your customers hear. Use these tone tips to make sure your customers feel good about doing business with you

In three minutes, Louis C.K. delivers a brilliant lesson on how our tone of voice changes what people hear when we talk.

Why am I talking about comedian Louis C.K. on a blog about customer service?

Two reasons:

  1. I needed to figure out a way to justify Netflix as a business expense (done).
  2. In a single three-minute clip from his show Louie, he shows us why our tone of voice matters so much in customer service (and in every other interaction we have).

Back in the first season of the show, actor Matthew Broderick invites Louie to play a bit part as a cop in Broderick’s newest crime drama.

Louie’s job? Deliver a single line.

But with every failed take, it becomes ridiculously clear that in order for your words to be effective, how you say them is just as, if not more important than what you say.

By understanding how tone and mood can change the meaning of your words — even online, where you’re usually writing instead of speaking — you can make huge differences in the way your customers think about their interactions with you.

First, let’s dig into some research on tone and how it works, whether we’re hearing words or reading them.

Understanding How Our Brains Process Tone of Voice

How can tone make such an impact on the way our words are interpreted?

Well, part of the reason is that our brains process the words we hear separately from the tone in which we hear them.

In fact, Sophie Scott, a neurobiology researcher at University College London, published a study suggesting that words and tone are sent to two completely different parts of our brain:

So when we say something to customers — or anyone — their brains interpret the meaning of what you say by both your words and your “melody.”

But we don’t just interpret tone from words we hear; our brains process the words we read in a similar way.

A 2012 study in the Journal of Neuroscience suggests that when we read, we trigger an “inner voice” in our brains that reads the words as if we were hearing them, allowing us to pick up on nuances like tone and inflection.

Think about the last fiction book you read that you really loved. Do you remember coming across passages where the main characters were speaking, and you could almost “hear” their voices in your head?

Try reading this paragraph from Sinclair Lewis’ Main Street silently, and see if you find yourself hearing the tone in the characters’ — especially the baby’s — words:

Pretty crazy, right?

Now imagine that every time you write an email to a customer, they’re doing the exact same thing you just did, except in their heads, they’re assigning that voice and tone to you.

That’s why it’s so important to consider the impact of our tone, even when we’re sitting behind a keyboard.

Tone in Customer Service: What Matters Most

Sure, we understand that using the right tone is important, but what is the right tone?

Well, that depends. On a lot of things. But below, you’ll find the three most important factors when it comes to customer service tone; act on these, and you’ll be ahead of 99% of your competitors when it comes to delivering great service in the right tone.

1) Casual vs. Formal Tone

Should your emails read like they were written by someone wearing a suit, or a t-shirt?

While the right answer largely depends on who your customers are (customers who wear suits are more likely to want service to match), a recent survey of the best tone for online support by the consulting firm, Software Advice, sheds some light on the issue.

Of the 2,000+ customers surveyed, 65% of online customers — across all ages and genders — prefer a casual tone in customer service over a formal one.

But there’s a twist: that preference shifts significantly when customers are being denied a request.

78% of respondents said that an overly casual tone (like using slang or emoticons) has a negative impact on their experience when the agent is denying a request.

By being too casual when you have to say no to a customer, you imply that you’re not taking their request seriously. It’s something that bugs me to no end, and as it turns out, it bugs your customers, too.

Another question that Software Advice’s survey explored was how customers reacted to emoticons in support emails.

The result? For most people, emoticons are just fine.

Only 35% of customers found emoticons too casual.

We use them from time to time in our own support interactions, so I wouldn’t hesitate to say it’s okay, but be aware of the situation. When you have to deliver bad news, stay away from the smileys.

As with all “rules” in customer support, take these with a grain of salt: the customers surveyed may not necessarily represent your customers (more on that below), but you can use these findings as a starting point for finding the best tone.

2) Positive vs. Negative Tone

In the book Words Can Change Your Brain, researchers Andrew Newberg and Mark Robert Waldman write that hearing positive words can actually change our brain.

Words Can Change Your Brain by Andrew Newberg and Mark Robert Waldman

They found that people who used and heard positive language regularly developed changes in their brain that made them feel more positive all of the time.

You can use the power of positive words in customer service to make your customers have more positive experiences, both in the moment and over the long-term course of your relationship with them.

One of my favorite examples of this comes from Carolyn Kopprasch, Chief Happiness Officer at Buffer.

To make her tone more positive, Carolyn removed the word “actually” from her vocabulary when talking to customer.

Notice how different the tone is totally different in these two extremely similar sentences:

Carolyn also dropped the word “but.” Again, the difference is easy to spot:

It’s simple but powerful: just by removing a few negative words from our customer interactions, we can completely change the way what we say is perceived.

3) Context-Specific Tone

As we saw with the dangers of being too casual when saying “no,” the right tone depends a lot on the situation.

It also depends on the specific customer.

But there’s good news: simply by practicing, you can develop the ability to pick up on each customer’s tone and mood, and adjust your tone to match it appropriately.

There are a few easy cues you can practice spotting in any email:

  • Does the customer use emoticons, exclamation points and slang? (This is a green light for you to reciprocate.)
  • Does the customer sound like they might not be totally fluent in your language? (In this case, you need to be much more careful with nuances like slang.)
  • Does the customer sound frustrated? (Turn up the empathy and use tone that’s understanding, apologetic and reassuring.)

One company that does this really well is JetBlue. You can learn a lot about tone by watching their Twitter feed.

Notice how they tailor their tone to each customer.

When the customer is frustrated, they focus on empathy and apology:

When the customer is happy, but not using a super-casual tone, they do the same:

And when the customer makes it obvious that casual and edgy are both okay, the airline reciprocates:

Learning to pick up on your customers’ subtle cues makes delivering service in the right tone of voice much, much easier.

4) Empathetic vs Detached Tone

An empathetic tone isn’t just about being nice; it’s about genuinely recognizing the customer’s situation and expressing that understanding back to them.

Imagine a customer who’s facing a problem that’s caused them significant inconvenience.

A detached response would merely acknowledge the issue and maybe provide a solution.

On the other hand, an empathetic response would first recognize the frustration, inconvenience, or disappointment the customer feels, before moving on to the solution.

For instance, instead of saying, “You need to reset your device,” an empathetic approach would be, “I understand how disruptive it can be when your device isn’t working as expected. Let’s try a reset to see if that resolves the issue. I’m here to guide you through each step.”

Empathy does more than just soften the blow of bad news; it builds a connection between the customer and the company. 

Perfecting Your Customer Service Tone

One of the biggest challenges of finding the best tone is that there’s no “right” answer that works every time.

It depends on you, your brand, your voice and perhaps more importantly, your customers, who they are, and how they feel in a given situation.

But in customer support, every single interaction is a chance to get better. So by starting with a few research-backed guidelines and practicing conscious changes to your tone in every interaction, you’ll become an expert in very little time.

Have you found your own customer interactions impacted by tone? Have you noticed any changes in your customers’ reactions when you’ve changed your tone?
