RTFE
Read The Fucking Email

Similar to RTFM, a term showing the frustration of being bothered with questions that were already answered by persons in a chain of emails.  People who use "RTFE" may be considered rude, but the truly rude person is the one who can't be bothered to read the previous responses in an email chain and want to have all the answers handed to them personally.
"How much does that software packages cost?"
"RTFE, Joe started this email off with a cost breakdown of hardware and software pricing."
