Earlier this year, Zendesk set the fine folks at Dimensional Research on the task of answering this question: “What exactly is the long-term impact of ‘good customer service’?” No one working in customer service will be surprised to hear that the research reveals that good service really does matter—and that bad service can harm your business. But if you’re like us, you’ll be surprised by just how much it matters and how long the effect lasts.

Zendesk’s latest infographic highlights some of the findings, finally getting to the good, the bad, and the ugly truths of how consumers are influenced by the type of customer service experiences they have.
