Ask How do you stay calm when a client sends a long complaint message and you are not sure how to respond?

[Edward22]

Receiving a long complaint from a client can feel heavy, especially when the message is full of issues and strong words. It is easy to react quickly or feel stressed, but that can make things worse. Taking time to understand the message seems important, but it is not always easy to stay calm. In that moment, what helps you slow down and think clearly, and how do you respond in a way that keeps things professional without making the situation worse?
