My advice is to make sure you are reading the submissions guidelines for each lit mag you submit to. Some are more....picky than others. Make sure, as best you can that the piece you want to submit fits their 'vibe' for lack of a better word. Read some of the works they have published to get a feel. Keep some sort of track, like an excell spreadsheet of the stories you submit to. Pay attention to the word count limit, if listed. Some of us have our own 'hard pass' on where we submit to or don't. Only you can decide if, for example, you're willing to wait say 6 months or more for a response.
