How Customer Service Can Turn Angry Customers into Loyal Ones

Good customer service seems like common sense for businesses. But how valuable is it really?

Until now, this has not been rigorously quantified across different companies. Businesses are understandably reluctant to share their CRM and sales data, and most research in this field has been based on surveys. But as more Americans seek customer service online, social media offers a better platform for analyzing interactions between service reps and customers.

Using data from Twitter (where one of us works), we designed an experiment to study customer service interactions in two industries that generate a significant number of customer service complaints: airlines and wireless carriers. We found that prompt and personal customer service does indeed pay off — customers remember good and bad customer service experiences, and they’re willing to reward companies that treat them well.

We identified more than 400,000 customer service-related tweets sent to the top five major airlines (American, Delta, JetBlue, Southwest, and United) and top four wireless carriers (AT&T, Sprint, T-Mobile, Verizon) in the U.S. from March 2015 to April 2016. Our sample of tweets was comprehensive, including complaints, questions, and comments. Since all tweets are public, we could review the entire conversation between the customer and the customer service agent (except direct messages) and code the interaction for attributes such as customer sentiment and tone (e.g., Is the interaction praise or scorn? Is the customer happy or angry?)

We then contacted these customers on Twitter, up to six months after they tweeted at the companies, and invited them to take a brief survey. Without providing a reason for the survey, we asked them to participate in a common market-research exercise called conjoint analysis to see if their customer service experiences affected how they valued the brands.

For example, for customers who had tweeted at airlines, the conjoint asked them to imagine buying a ticket for a two-hour non-stop flight. They had to choose between several combinations or “offers” that varied across dimensions such as airline, seat type, on-time arrival rate, and fare — similar to how customers would shop for fares on sites like Kayak or Expedia. We offered a similar exercise for wireless service customers.

From the conjoint exercise, we could discern what value, in dollar terms, customers attributed to their preferred airline. On Twitter, 1,877 users completed the conjoint exercises – 673 of them had received responses from companies, 375 received no response, and 829 had no customer service interaction and served as our control group for baseline willingness to pay.

We then tested our hypothesis: do customers who had a positive interaction with a brand’s customer service representative value that brand more? Or in management parlance, when a brand provides better customer service, will customers reward that brand with greater loyalty or pay a price premium?

Good Customer Service Matters on All Platforms

Customers who had interacted with a brand’s customer service representative on Twitter were significantly more likely to pay more for the brand, or choose the brand more often from a comparably-priced consideration set, compared to our control group of customers who had no such interaction. On average, across all tweets and regardless of whether the customer used a negative, neutral, or positive tone, we found customers who received any kind of response to their tweet were willing to pay almost $9 more for a ticket on that airline in the future. This extra $9 can be thought of as incremental brand value the airline has gained in the customer’s mind. In other words, all else being equal, a customer would be willing to buy a ticket from the airline even if the airline cost $9 more than its competitors.

We found similar results for wireless carriers. Customers who received any kind of response to their tweet were willing to pay $8 more, on average, for a monthly wireless plan from that carrier in the future, compared to the control group. Unlike airline tickets, wireless plans are monthly and recurring, so an $8 per month higher premium can lead to a significant revenue boost.

We also surveyed customers on their likelihood to recommend the brand to others, so we could derive a Net Promoter Score (NPS), a common measure of customer loyalty. We found that receiving a response improved NPS by 37 points for airlines and 59 points for wireless carriers, consistent with our findings from the conjoint exercise. (This bump is significant considering NPS scores range from -100 to 100.) In addition, these effects held up for at least six months after the interaction, suggesting some permanence to the positive impact of good service.
