Thanks for sending "---" our way, but unfortunately it's not quite for us. Sorry for not making as personal a reply as we would like to but the volume of submissions doesn't always make it possible.
Thanks for sending [Title] our way, but unfortunately it's not quite for us. We're sorry for not making as personal a reply as we would like to but sometimes we're swamped by submissions and trying to catch up (which is very much the case right now).
And sometimes a story is perfectly good but for whatever reason doesn't quite grab us -- maybe it's a type of story our taste tends not to run toward, or it depends on a particular pop culture context we don't know well -- and any feedback we offer might cause the story more harm than help. But it's never meant as disrespect to a story or its author.

Thanks for sending "---" our way. Although elements of it caught our attention, we're afraid it's not quite for us.
We wish you success placing this elsewhere.
Best, Necessary Fiction
