Its missing "because you are my boss and I know the person I write to will only listen to me when he sees someone more important than me is also seeing the message."

Why I Bcc’ed you on this email: 🔴 Look at this bullshit

Forgetting a large slice: "this thread is absolutely insane and don't wamt you to miss the office drama... i mean your expertise may be needed"

At my old job my boss was notorious for having last-minute epiphanies that would derail the entire project, so my cc-ing was 100% to have a written record of me advising not to do it for when they were looking for someone to blame afterwards lol

"I thought it would be helpful" sounds redundant with all of the other choices, which are helpful in different ways.
