Reply All mistakes in business email happen when you respond to every recipient on a message without checking whether each person needs your answer. The button is convenient. The damage is fast. Here is what typically goes wrong.

Reply All also changes who sees your words. A joke meant for one colleague reaches the client on the copy list. A frustrated line about a vendor lands in the vendor inbox. Once sent, you cannot shrink the audience.
