That is only working if you are the only one doing this. If everybody in the team starts repeating everything very detailed, this soon becomes completely unproductive and ignored. Think one information mail from one system might be a good idea, but when you start getting 1000 automated mails every day like I get right now you are actually not informed at all. The key to success is focusing on a small number of messages that you really want to get to people and then overcommunicating them.
