Think of a sentence containing "at the end of the day". Now remove that phrase. Does your sentence convey any less information? Unless the time of day is actually germane to what you are saying something (e.g. "At the end of the day I draw the curtains and have a cup of cocoa.") then it is just superfluous verbiage. And that's bad because it obscures the message.

"Boilerplate" is jargon, but conveys some information, so I think that's OK.
