I write the email, I hit send, and nothing happens, no clicks, no replies, nothing. The words are all correct but they just lie there flat on the page, and I can tell they don't make anyone feel or do anything. I read other people's writing that crackles and I have no idea how to get mine to do that.
More people experience this than they realize.
Your writing is flat and doesn't move anyone to act.
