A perfectly fine rejection letter, notable if only for its complimentary closing:
As a quasi-professional writer of cover letters, I have struggled mightily with the delicate matter of the closing salutation. One must strike an impossible pose of quirkiness, casual solicitation, and deferential gratitude … but how best to sign off on a correspondence in which the author is essentially offering himself up for near-certain artistic immolation? How to gracefully leave a room that one never should have entered in the first place?
I had never considered using “Cordially,” but here, in response to my submission, and in the spirit of the somewhat pompous and erudite detective after which Ellery Queen’s Mystery Magazine is named, it works splendidly.
cor dial adjective \’kor jel\
3 b: warmly and genially affable <cordial relations>
A boilerplate rejection letter is, if nothing else, a cordial affair.
