If you find a magazine accepting submissions and they don't name a limit for how many stories to submit at once, and you have multiple stories that fit the description of their genre/style.... How many stories do you submit at once?
I have 3 stories out to one place (all for different catagoreis). I also have 3 stories out to another place (all the same catagory).
In the second case, it's a college literary review, which means (in my experience) that a bunch students read the slush pile and discard most of the submissions before the main editors ever see the smaller list of maybes. And one of the editors is a writer I really like, so I submitted 3 short stories that might get through.
Is this acceptable submission behavior?
I have no idea, but it sounds like a good plan to me.
If they wanted it otherwise then they should have specified, right? Sounds like you are all good to me.
It probably depends on the length. Submitting 3 long stories at once may annoy the editors. Same thing with not submitting the stories together (unless they are going to different editors). Submitting 3 short ones together is fine.
