The accountant in our firm was sending an outstanding expenses summary to me by email and CC to our boss without saying anything about the statement. I just want to ask her what this email for? As usually she just mailed a reimbursement check to me without giving any other information in advance. I have no idea what she meant.
But can I just say,"what is this email for?" to her. And my boss will see it as well.
I would go with something like "I received this email from you a couple of days ago but I'm not sure why. I'd be grateful for clarification. Thanks". Make sure you include a copy of the original email.
