Avoid cliché language for communicating
Remember when you were little and you ate your sister's Halloween candy and your mom made you apologize to her? You said, "Sorry." Yeah, that type of insincere apology might have worked when you were eight years old, but it doesn't work when you're apologizing to a customer in an email. Let me show you why you should avoid cliched language and how to use specific, genuine wording when you apologize to a customer. Sometimes, an apology is all we can offer a customer, so we need to do it right.
Let's say a customer sends your company this email. Your company messed up the delivery time, so you'll probably refund the shipping charges, but it's not just the refund that makes the customer feel that you care. It's the words you use when you say you're sorry. Here's the classic, cliched way of apologizing. "Thank you for contacting us regarding this matter. "We regret any inconvenience this might have caused." Stop, we are not going to use those words when we apologize to a customer.
"We regret any inconvenience this might have caused"
