Sending email to editor about reason of rejection of paper My manuscript was rejected without sending to peer review, of course the editor whom I sent my paper is an expert in my field and he rejected it without any report. (it took one and half month with editor). Just the editor in chief told that the editor can not recommend this paper to publish in Journal X. Now I want to ask about sending another email to Editor to ask about his suggestions on my paper. For example, if he recommend another journal or some advice on improving my paper? Can I send such direct email to him?


  The editor who rejected my paper is the editor of several journals, what about  sending my paper to him through other journals' which he is on editorial board as well?
It is not the editor’s job to give you advice on how to improve your paper or where to submit it. And it is the editor’s job to do lots of other things, which usually keep them pretty busy. So at the very least, you’d be imposing on them by contacting them with such questions. You might get lucky and get some advice, but be aware that you are essentially betting on the editor being willing to spend time answering a question from a random person they don’t know and whose question they have no professional obligation to answer. If you lose the bet (or even potentially if you win the bet) it might not leave the best impression.

As a general rule, it makes more sense to discuss these sorts of questions with your adviser, a mentor, or a colleague you are on friendly terms with.
