The point it sounds like you are trying to make is “Email is not evidence.”
By writing “I don’t know how decisive is an email conversation printout.” after your question, it reads as if you ask the questions just so you can give your own answer.
By placing “Hah !” before the question also implies that the answer to the question is so obviously negative that it doesn’t need to be answered.
If you do both of those things, almost no one will see what you wrote as a question, at least in English. I don’t know Parisian French, so it might not read that way in other languages, and you might not have meant it that way.
