If it's not important enough for me to read, then I don't read it.
That simple. I'm not going to waste my day "doing e-mail".
"did you get my E-mail?"
Yeah, but the subject wasn't descriptive enough so I just didn't read it. You probably just copied me anyway. If you need my attention e-mail me directly and I will respond, otherwise I'm not going to do your job for you. "did you get my E-mail", no I didn't. I got copied of your ramblings and action items but you choose to just copy me which means "FYI", therefore I have no actionable items in said e-mail that I didn't read.
so fuck you Mr. CC everybody. You expect me to recognize you have a problem and just decided "well if I copy everybody somebody will jump in and take care of it!" No, fuck you. I will not jump in just because you CC'd me. That's what fools do, now I give you credit Mr. CC everybody because there are a lot of fools who live and die by responding to their E-mail. That's what he does, That's ALL he does. He was built to respond to E-mails and he simply will NOT stop until every single E-mail is terminated.
An e-mail is the same as a MEMO, so learn proper communication protocol.
