Cover Letter for Journal Submission: Template + Examples
Table of contents
A cover letter for journal submission is a one-page note to the editor that states what you are submitting, summarizes your main finding in plain language, makes the case that the work fits the journal, and confirms the required declarations. Editors skim it in under a minute, so lead with fit and novelty, not a restated abstract.
What editors actually read (and what they skip)
When your manuscript arrives, a handling editor makes a first call: desk-reject, or send it to reviewers. The cover letter is read alongside your title and abstract to make that call. It gets seconds, not minutes.
Here is what the editor is scanning for:
- What is new. One sentence they can repeat to themselves (and later to reviewers) about why this paper exists.
- Whether it fits. Journals are scoped. The editor is checking that your paper belongs in their journal, not that it is generally good.
- Red flags. A missing ethics statement, hints of dual submission, an author list that does not match the manuscript.
- Practical help. Article type, reviewer suggestions, and any context the submission form did not capture: a related preprint, an earlier presubmission inquiry.
What they skip: praise for the journal, the story of your career, and any paragraph that reads like the abstract they are about to read anyway.
A letter that never makes the fit case does real damage. When an editor cannot see why the paper belongs in their journal, that is a recurring desk rejection trigger: the manuscript is returned before anyone reviews it.
Cover letter for journal submission: the annotated template
Every element below maps to something the editor needs to decide or confirm. Keep the whole letter under one page.
[Your name]
[Department, Institution]
[Institutional email: must match the corresponding author]
[Date]
Dear Dr. [Editor's last name],
→ Use the handling editor's name if the journal lists one;
"Dear Editors" is acceptable otherwise. Triple-check the
journal name everywhere it appears.
PARAGRAPH 1: Submission statement (1–2 sentences)
We are pleased to submit our manuscript, "[full title]," for
consideration as [article type: use the journal's own label]
in [Journal Name].
→ If the paper was invited, transferred, or follows a
presubmission inquiry, say so here.
PARAGRAPH 2: What you found (2–3 sentences, plain language)
In this study, we [what you did, one clause]. We found that
[main result, in words a non-specialist editor can follow].
This matters because [one concrete implication].
→ Not the abstract. No methods detail, no statistics dump.
One finding, one reason to care.
PARAGRAPH 3: Why this journal (1–2 sentences)
This work fits [Journal Name]'s scope on [specific area] and
will interest readers working on [specific audience or use].
→ Be specific enough that this sentence could not be pasted
into another journal's letter.
PARAGRAPH 4: Declarations (one short block)
This manuscript is original, has not been published elsewhere,
and is not under consideration by another journal. All authors
have approved the manuscript and agree with its submission.
[Ethics approval: committee and protocol number, if applicable.]
[Competing interests statement.] [Funding statement, if the
journal wants it in the letter.]
→ Check the author guidelines: journals differ on which
statements go in the letter versus the submission system.
PARAGRAPH 5: Suggested and opposed reviewers (if invited)
We suggest the following qualified reviewers: [3–5 names,
affiliations, emails; no recent collaborators or close
colleagues]. We request that [name] not be invited to review
this work, due to [brief, professional reason].
→ Only include this if the journal asks for or permits it.

A filled-in example for a biomedical paper
This is a composite example based on common patterns in biomedical submissions. The study, authors, and journal are fictional.
Dear Dr. Alvarez,
We are pleased to submit our manuscript, "Early Postoperative Glucose Variability Predicts 90-Day Readmission After Cardiac Surgery: A Prospective Cohort Study," for consideration as Original Research in the Journal of Metabolic Health.
In a prospective cohort of 412 adults undergoing cardiac surgery, we found that glucose variability in the first 72 hours after surgery predicted 90-day readmission independently of diabetes status and mean glucose. Current discharge risk models rely on static glucose thresholds; our results point to a routinely collected signal that identifies at-risk patients before they leave the hospital.
This work fits the journal's scope on metabolic monitoring in acute care and will interest your readers working on perioperative risk stratification.
This manuscript is original, has not been published elsewhere, and is not under consideration by another journal. The study was approved by our institutional review board (protocol 2024-118), and all participants provided written informed consent. All authors meet ICMJE authorship criteria, have approved the manuscript, and declare no competing interests. Preliminary results were presented as a conference poster; the full analysis is unpublished.
We suggest the following reviewers: three arm's-length experts with affiliations and emails. We have no opposed reviewers.
Thank you for considering our manuscript. I am the corresponding author and can be reached at j.okafor@university.edu.
Sincerely, Dr. Jane Okafor, on behalf of all authors
Notice what this letter does not do. It never says "groundbreaking." It gives one finding and one reason to care, in language an editor outside the subfield can follow. And every declaration the editorial office must confirm sits in a single paragraph, so nothing has to be chased later.
Five mistakes that get cover letters ignored
| Mistake | Why it backfires | Do this instead |
|---|---|---|
| Pasting the abstract | The editor reads the abstract next; the letter adds nothing | Two or three plain-language sentences: what you found, why it matters |
| Overselling ("groundbreaking," "paradigm-shifting") | Editors read hype as inexperience and discount the claim | Let one specific, concrete finding carry the novelty |
| A generic letter, or the wrong journal name | Signals a mass submission; a leftover journal name suggests a prior rejection | Rewrite the fit paragraph for each journal, then proofread every name |
| Burying the contribution | Editors will not dig; a main finding in sentence nine is invisible | State the finding by the second paragraph |
| Ignoring required statements | Triggers administrative back-and-forth, delays, or a desk return | Check the author guidelines and mirror every required declaration |
These are largely the same failures that sink manuscripts in review (unclear contribution, inflated claims), surfacing one page earlier, and they overlap heavily with the reasons papers get rejected outright. A pre-submission review with Thesify Reviewer, an AI peer review tool, flags weak contribution framing and unsupported claims in the manuscript itself, so the letter's one-sentence novelty case has something solid behind it.
How cover letters differ across disciplines
A cover letter for submission to a scientific journal in biomedicine carries the heaviest declaration load. Elsewhere, the weight shifts.
| Field | What the letter emphasizes | Typical extras |
|---|---|---|
| Biomedicine / life sciences | Clinical or biological significance in plain language | Ethics approval, trial registration where applicable, ICMJE-style authorship and competing-interest statements, reviewer suggestions |
| Social sciences | Contribution to theory or evidence, and fit with the journal's ongoing conversation | Originality and no-dual-submission statements; fewer formal declarations |
| Humanities | Fit with the journal's editorial focus | Often minimal; some journals do not expect a letter at all |
| Conferences (CS, engineering) | – | Generally no cover letter; submission forms and author checklists replace it |
Conference submissions generally do not use cover letters. The submission platform collects conflicts of interest, topic areas, and declarations through structured forms, and program committees do not see a letter. If you are moving from conference publishing to journals, the cover letter is a new genre; budget time for it.
Check the journal's own requirements first
Author guidelines differ, and some journals require specific statements or content in the cover letter itself: anything from clinical trial registration numbers to a note on related manuscripts under review elsewhere, and some provide their own required wording or template. Before you send anything, skim the journal's instructions for authors and mirror what they ask for, in their order and their terms. An editor who sees their own checklist reflected back reads the letter faster and trusts the submission more.
The letter is one piece of a longer pipeline: target journal choice, formatting, submission system fields, and what happens after review. For the full sequence, see our guide on how to publish a research paper.
FAQ
How long should a cover letter for journal submission be?
One page maximum: typically three to five short paragraphs. Editors triage quickly, and a longer letter does not get more attention; it gets skimmed harder. If you cannot fit the finding, the fit case, and the declarations on one page, cut the finding description first, not the declarations.
Who should sign the cover letter?
The corresponding author signs, explicitly on behalf of all authors. The name and email must match the corresponding author listed in the submission system. Some journals ask the letter to confirm that all authors approved the submission; include that sentence in the declarations paragraph.
Should I suggest reviewers in the cover letter?
Only if the journal invites or permits it; many collect suggestions through the submission form instead. Suggest three to five experts at arm's length: no recent co-authors, collaborators, or colleagues at your institution. Editors are not obliged to use your suggestions, but sound ones speed up reviewer assignment.
Do all journals require cover letters?
No. Many journals treat the letter as optional, a few require it, and conferences generally do not use them at all. When it is optional, a short letter is still usually worth writing: it is your only chance to frame fit and novelty in your own words before the editor forms a view from the abstract alone.
