When writers send out manuscripts to editors, there are three types of responses they'll get.
1 -- Nothing. No response. They've read your submission on their computer or cell phone and just deleted it and went on to read the next submission.
2 -- A rejection, usually by email, which often makes a comment about your lovely writing and that they like it, but that they just didn't love it enough to buy it. Sometimes they include a statement that they'd like to see more of your work, which is nice.
3 -- Acceptance. They want to buy it and publish it !!!
Recently I've been mostly getting numbers 1 and 2.
