Ava has some questions about the use of pen names.
Should an author who is using a pseudonym sign their query letter with both their real name and the pen name? (ie Jane Doe writing as Suzy Screamsalot)
What then is the protocol if one's work is accepted? Does the editor refer to the author using their pen name in correspondence or their real name?
Yes, your query letter or submission should indicate both real name and pen name. Please never provide only your pen name.
The editor is normally "talking" to the real you, and so would likely address you by your real name. But this can vary with each relationship. The author may prefer to be called by her pen name. Or if the author's real identity is a deep secret, both editor and author may prefer to use the pen name to prevent any slip of identity confidentiality.
A related issue: The publisher may ask you to use a different pen name than the one you originally listed, especially if you are not previously published under that pen name in this genre. Your pen name may conflict with an existing author at that publisher, or may be a name the publisher feels is ineffective or downright bad. It's amazing how many aspiring erotic romance authors pick ridiculous pen names that sound like a porn star or are just sickeningly "cutesy".
