When submitting work to academic journals, the cover letters are often treated as a formality. Authors meticulously polish their manuscripts but neglect the cover letter, assuming editors won’t scrutinize it closely. In reality, the cover letter can make or break your submission. Editors receive hundreds of manuscripts weekly, and your letter is the first impression—subtle cues can determine whether your work is sent for peer review or rejected outright. Editors also expect cover letters to align with international submission standards, particularly those outlined by the International Committee of Medical Journal Editors (ICMJE).
Here’s what editors actually look for in a cover letter, even if they never verbalize it.
The Purpose of a Cover Letter
A cover letter job is not just a summary of your paper—it is your introduction to the editor. Its purpose is to:
- Demonstrate the novelty and relevance of your work.
- Highlight why the manuscript fits the journal’s scope.
- Assure the editor that your research adheres to ethical standards.
Many authors misuse the cover letter by repeating the abstract verbatim. Editors spot redundancy instantly.
Instead, focus on why your work matters and how it contributes to the field.
For ethical submission standards, refer to COPE Guidelines.
Brevity Speaks Volumes
Editors are busy. A concise, well-structured cover letter is far more effective than a verbose one. As a rule of thumb, most cover letters should be no more than 300–400 words. This answers the common query: “how many words should be in a cover letter?”
Break your letter into short paragraphs:
- Opening paragraph: Introduce the manuscript and your motivation for submission.
- Middle paragraph: Explain the novelty and relevance to the journal.
- Closing paragraph: Offer suggestions for reviewers and affirm ethical compliance.
This structure demonstrates organization and respect for the editor’s time.
Personalize Your Pitch
Editors can tell when a letter is generic. A tailored cover letter cover that references the journal’s focus or recent publications signals that you have done your homework. Mentioning specific editors’ interests or aligning your manuscript with the journal’s audience improves your credibility. Citations from Google Scholar are highy reputble in academia.

Show, Don’t Just Tell
Editors don’t just want claims—they want evidence. Statements like “our study is groundbreaking” mean little without context. A strong cover letter provides concrete highlights:
- Key findings with direct implications.
- A brief explanation of methodology strength.
- Relevance to current debates in the field.
For example, a cover letter for a scientific journal should concisely describe experimental design and main results while staying reader-friendly.

How to Close Out a Cover Letter
Many authors stumble at the end of their letters. The closing paragraph should be confident, polite, and actionable. Editors appreciate clarity about next steps:
- Confirm that all authors have approved the submission.
- Suggest potential reviewers if required.
- Express openness for editorial guidance.
A subtle, effective conclusion answers the question: “how to close out a cover letter?”
Avoid generic statements like “Looking forward to your consideration” without context.
Ethical Transparency Matters
Editors are trained to detect ethical lapses. Cover letters that fail to disclose conflicts of interest, prior submissions, or funding sources can raise red flags.
Transparency here demonstrates integrity and professionalism. Include statements on:
- Ethical approval for studies involving human or animal subjects.
- Any prior submission or preprint postings.
- Conflicts of interest or funding sources.
Neglecting these details can slow down or even derail the review process.
Consult World Health Organization Ethics Guidelines for clarity.
Formatting and Tone: Subtle Signals
The tone of your cover letter communicates professionalism.
Use:
- Polished, simple language over jargon.
- Active voice for clarity.
- Proper formatting: consistent font, spacing, and alignment.
These seemingly minor details signal to editors that you are meticulous—a trait they value highly in authors.

Final Thoughts
| Editor Expectation | What They’re Quietly Checking | Why It Matters |
|---|---|---|
| Journal Fit | Does the manuscript clearly match the journal’s scope? | Poor fit leads to desk rejection before peer review. |
| Research Novelty | Is the contribution clearly stated in plain language? | Editors need a fast reason to send it out for review. |
| Ethical Transparency | Are approvals, conflicts, and funding disclosed? | Missing disclosures raise immediate red flags. |
| Clarity & Brevity | Is the letter concise and well-structured? | Long, vague letters signal weak communication skills. |

Writing a compelling cover letter is both an art and a science. A strategic, concise, and ethically sound letter increases your chances of moving past the first editorial screen. Editors may not vocalize every expectation, but understanding their unspoken priorities can set your manuscript apart.
