No writer enjoys having work rejected. I no longer blog about my rejection slips, but I believe rejection is a necessary part of the submission process. If nothing else, it's a clear sign to writers it's time to move on. Try this piece elsewhere, or write something new.
Some markets "don't reject." They claim to only accept or to make picks ("Don't complain if your work isn't picked."). While an acceptance-only policy might save some egos, it seems to be merely rejection without the letter. Does it save writers' egos, or leave them without closure?
Some of these markets want to build reputations as unflinching, cutting edge, yet they balk at sending rejections? Say what you will about form rejection; at least it's a response.
