Apologize:  A sincere apology can go a long way toward soothing someone’s feelings of anger or frustration.

Thank:  Thank the customer for bringing the problem to your attention and for using your product or service. After all, they could have chosen to simply leave a negative review and never use your business again. They took the time to give you a chance to fix the issue and change their customer experience for the better.

Wow Icon

WOW Acronym Customer Service Meaning

WOW isn’t actually an acronym; it refers to the WOW factor in customer service. It’s a method of delivering an incredible customer service experience and pleasant surprise that differentiates you from other companies—making your customers go, “WOW! Now that’s amazing service!

WOW prizes emotional intelligence, empathy, enthusiasm, and thoughtfulness. What feeling or emotion do you want to leave the customer with? WOW doesn’t settle for the status quo. It’s going above and beyond to deliver service that customers will tell their friends and family about. “Larry from Blue Summit was SO kind and understanding. She was SUCH a good girl!” 🐶😊

Delivering this kind of experience converts potential customers and drives brand loyalty.



Smile Icon

SMILE Acronym Customer Service Meaning

The customer service acronym SMILE is similar to WOW in that it’s not actually a set-in-stone acronym. But there’s a good reason you’ll see the words customer service and smile used together, and it’s because the act of smiling is one of the most important factors in providing good customer service.

After all, actions speak louder than words, and a smile is one of the easiest ways to communicate that we’re sincere.

Smiling doesn’t only trigger a happiness response in the customer. Science says that just the act of smiling can lift your mood, lower stress, and boost your immune system. Even if you don’t feel like smiling, faking a smile sparks the same chemical reaction in your brain as a genuine smile, so your happy hormones dopamine and serotonin are released anyway. 

If you’re dealing with a particularly negative customer or your long day is beginning to zap your energy, force a smile. Faking it will keep you from becoming overly frustrated or agitated, so you can focus on delivering great customer service.

Customer Service vs. Customer Experience

The difference between customer service and customer experience is subtle but important.


Customer service is the support you provide a customer throughout their entire interaction with your business—before, during, and after they purchase or use your product or service. Good customer service, such as being polite, contrite, warm, professional, attentive, and quick, results in a good customer experience.

Customer experience is the overall perception customers have of your brand or business. It takes into account every step of the customer journey. If a customer loves your product but has had even one unpleasant experience with your customer service, it’s going to negatively impact their experience and overall impression of your brand, and vice versa.


Customer experience won’t affect your customer service, but your customer service will affect the customer experience.
