How to start a cover letter during submission? I'm submitting a paper to an Elsevier journal. One of the submission steps seems to be writing a cover letter to the journal office. They say that:


  Please enter any comments you would like to send to the Journal
  Office.


In order to start the cover letter, I wanted to write:


  Dear editor


but after googling the sample cover letters, I found out that I should write the editor's name. But the question is that which editor? 

The journal has one editor-in-chief and multiple other editors. Which one's name should I mention? Will the editor-in-chief investigate the submission or who?

Should I use another terms instead of "dear ..."?
Don't obsess over it. Dear Editor is fine unless you have already corresponded with them. In fact, if you direct it to an individual by name it might well be handled by someone else - especially in a large organization. 

Eventually you may get the name of someone who is responsible for managing your paper. Then you can be a bit more personal.
