Q: What should be the subject line of an email to the editor providing information about my article?
The journal I am going to submit my manuscript to does not require a cover letter. So, I am considering telling the editor the information which is usually written in cover letter (ex. short summary and importance of my study etc.) by email. Is there any effective title (subject line) for the email in such case?
You have not mentioned whether you are submitting the manuscript through the online submission system or through email. In case it is an email submission, you can use the following subject line: "Submission of an original research article in [journal name]." If you have already submitted the manuscript online and wish to write to the editor with some information on the lines of a cover letter, you can use the subject line "My submission titled [article title] to [journal name]."
