You don’t need to know EVERYTHING that goes on in your organisation, unless you’re a control freak like Mark McCormack. Set a rule in your inbox to delete and autorespond to all messages where your name is not in the main recipient list (To field). Politely inform the sender that you did not read the message due to a large volume of emails and that you only accept messages directly relevant to you. (you can always make exceptions in the rule for specific people)
