I foolishly submitted a short story to a magazine I’d never read. Their description of what they wanted sounded like a match, but when I later found a copy of the magazine I realized that I’d misinterpreted the guidelines. I didn’t like their stories and I doubt that they’d like mine. They take over 6 months to respond to submissions. I’ve just found another magazine where my story might fit better. Can I write to the first magazine and withdraw my story without getting put on a magazine editors’ blacklist?
This same thing happened to me when I was starting out. I sent a short piece to a magazine called Highlights. Then I saw a copy in my dentist's office and realized it was mainly for kids (although I did enjoy a feature called Goofus and Gallant). Anyway, I withdrew the piece and later sold it to Penthouse Forum.
Contrary to popular belief, there is no magazine editors' blacklist, nor will this affect your standing at NewYorkLitAgentsBlacklist.com. No harm will come from withdrawing the story from consideration, unless they decide to publish it just to embarrass you. Better give them a pen name.
