Dear Mr. X----,
Thank you for your email rejecting my story, "Y----," for publication in your magazine, Z------. Unfortunately, your rejection letter does not suit my needs at this time. I must therefore insist that you publish my story.
I wish I could respond to your submission in a more personal way than this form letter, but I receive many rejections, and it is, unfortunately, impossible to personally respond to all of them.
Best of luck in your rejection-letter writing endeavors. I look forward to seeing my story in print.
