How to Write a Cover Letter for a Journal Submission
A cover letter frequently gets written in the last ten minutes before submission, as an afterthought to the manuscript itself. Editors do read it, and a clear, well-targeted letter can genuinely help a paper get past the initial editorial screening, understanding what actually belongs in this document, and what to leave out, is worth the modest additional effort it requires.
State the fit explicitly, don’t assume it’s obvious
A sentence explaining why this specific journal, rather than a comparable alternative, is the right venue for the paper shows the editor you’ve actually considered fit rather than mass-submitting to a list. This is especially worth doing when the connection isn’t immediately obvious from the title alone.
Summarize the contribution in plain terms
A short, jargon-light statement of what the paper found and why it matters helps an editor who may not be a narrow specialist in your exact subfield quickly grasp the significance before diving into the full manuscript.
Confirm the standard declarations up front
Most journals expect explicit statements that the work is original, not under review elsewhere, and free of conflicts of interest. Including these clearly, rather than leaving the editor to look for them, speeds up the initial processing.
Mention prior versions transparently
If the paper extends a conference presentation or overlaps with previously published work, disclosing this directly in the cover letter, rather than letting an editor discover it later, is the more defensible approach and avoids any appearance of concealment.
Suggest reviewers only if the journal explicitly invites it, and do so thoughtfully
Some journals ask authors to suggest potential reviewers. When this option exists, suggesting genuinely qualified, appropriately independent reviewers, rather than close collaborators or friends, both serves the process well and reflects positively on your professional judgment.
Keep it short and skip the oversell
A cover letter that reads as a sales pitch, overstating the paper’s importance, tends to undercut credibility rather than build it. A concise, factual letter, typically under a page, that clearly states fit, contribution, and required declarations does the job without needing embellishment.
Address the editor by name whenever possible
A cover letter addressed to a specific editor by name, rather than a generic “Dear Editor,” is a small detail that signals genuine attention to the submission process, worth the extra minute it takes to check the journal’s current editorial team.
A cover letter checklist
- Journal fit stated explicitly, not assumed to be self-evident
- Contribution summarized in plain, accessible terms
- Standard declarations, originality, conflicts of interest, clearly included
- Prior related versions disclosed transparently, not omitted
- Kept concise and factual, addressed to a specific editor where possible
Frequently asked questions
How long should a cover letter typically be?
Generally under one page, a concise, well-organized letter is more effective than a lengthy one trying to cover every possible point.
Should I suggest reviewers if the journal doesn’t explicitly ask?
Not typically necessary, only include this if the submission system or journal guidelines specifically request it.
Is it appropriate to mention the paper’s potential impact or importance in the cover letter?
Yes, briefly and factually, but avoid overselling, a measured, honest statement of significance is more credible than an inflated claim.
