An editor at a mid-sized journal may receive several dozen submissions a week. For each one, the first thing they read is the cover letter, then the abstract, then a skim of the introduction and methods. The decision to send out for review or return the paper often takes shape in those first few minutes. A cover letter cannot rescue a weak paper, but a poor one can make a good paper look suspicious.
The most common mistake is also the silliest: a letter addressed to Journal B that still mentions Journal A from the previous submission. The editor learns immediately that the paper was rejected elsewhere and that you did not reread your own letter.
What the editor needs from your letter
In about a minute, the editor wants answers to four questions:
- What is the paper about, and what did it find?
- Why does that matter to this journal’s readers?
- Does the submission meet ethical and procedural requirements?
- Who should review it, and who should not?
Every sentence in your letter should serve one of those questions. If it does not, cut it.
The four-paragraph structure
Paragraph 1: introduce the manuscript
Title, article type (original research, review, short report) and one sentence on the research question. Skip the three-line formal preamble. If you know the handling or chief editor’s name, address them directly.
Paragraph 2: main finding and contribution
This is the paragraph that matters. State the main finding with a concrete number or image, then say how it changes current understanding. Two to four sentences. Do not paste the abstract: the editor will read it next.
Paragraph 3: why this journal
Connect your paper to a conversation the journal is already having. The strongest move is to name one or two recent articles in that journal that your study extends, replicates or challenges. Phrases like “your prestigious journal” are empty flattery and do nothing.
Paragraph 4: declarations
- The manuscript is original, unpublished and not under consideration elsewhere.
- All authors have approved the submission.
- Ethics approval for human or animal research, with committee name and reference number.
- Competing interests and funding.
- Data availability: whether and where data are shared.
- Any preprint or conference presentation of the work.
Weak sentences and stronger alternatives
| Weak | Why it is weak | Stronger |
|---|---|---|
| “This is the first study to…” | Hard to prove; one counter-example from a reviewer and your credibility drops | “Our search of three databases found no study testing… among…” |
| “The results are highly significant” | Says nothing about how or why | “The model reduces forecast error by 18% compared with the method most widely used in practice” |
| “This is a topic of growing interest” | True of nearly every topic | “The paper extends the findings of Smith et al., published in your journal last year, to…” |
| “We hope you will consider our paper” | Redundant; submitting already says that | Delete it |
Suggesting and excluding reviewers
Many submission systems ask for three to five suggested reviewers. Safe rules:
- Do not suggest recent co-authors, colleagues at your institution or former supervisors.
- Choose people who have published on your specific topic, with a mix of countries and career stages.
- Give institutional email addresses, not personal ones. Some peer-review fraud cases involved authors supplying fake reviewer addresses that led back to themselves, so editors are wary of free webmail accounts.
- You may ask for specific people to be excluded if there is a real conflict; give a short, neutral reason.
What to leave out
- Author biographies or publication lists.
- A full list of limitations: that belongs in the discussion.
- Apologies for your English: if you are worried, get the language edited before submitting.
- Requests for fast handling because of a thesis deadline: editors have no obligation to accommodate this, and it suggests the paper was rushed.
Letters for papers rejected elsewhere
You are not obliged to mention a previous rejection unless the new journal asks, or you are using a transfer option within the same publisher. That said, if the paper has been substantially revised in response to earlier reviews that you found useful, some authors choose to include the previous reports alongside a response table. This can shorten the process, but only when the revision genuinely resolves the main criticisms; attaching negative reports you have not addressed simply hands the editor a reason to reject.
In practice: a fill-in-the-blanks template
Dear Dr [Editor’s name],
We are pleased to submit our original research article, “[Title]”, for consideration in [Journal]. The study examines [research question in one sentence] among [population, setting].
Using [design, sample], we found that [main finding with a number]. This [extends, challenges, qualifies] the current view that [claim] and suggests [implication for research or practice].
The work builds directly on [related article] published in [Journal] in [year] and will interest readers working on [topic].
The manuscript has not been published and is not under consideration elsewhere. All authors have approved the submission. The study was approved by [committee], reference [number]. The authors declare no competing interests. Data are available at [repository].
Yours sincerely, [Corresponding author, affiliation, ORCID]
Aim for roughly 250 to 400 words, comfortably on one page.
Before you click submit, do three things: search the letter for the name of every journal you have previously submitted to, read paragraph two aloud and check it contains a concrete number, and match each declaration in paragraph four against the journal’s author guidelines.
Câu hỏi thường gặp
How long should a journal cover letter be?
Around 250 to 400 words, fitting on one page. Longer letters usually repeat the abstract or list limitations, neither of which helps.
Is a cover letter required for journal submission?
Most journals require or encourage one. Even when optional, a short letter stating the contribution and why you chose the journal helps the editor decide faster.
Should I say my study is the first of its kind?
Avoid it, because it is hard to prove. Describe what you searched and what you did not find instead, for example that no study has tested the model in a specific population.
How do I choose suggested reviewers?
Pick people who have published on your specific topic, who have not collaborated with you or worked at your institution, and give their institutional email addresses.
Do I need a new cover letter when resubmitting to another journal?
Yes. At minimum change the journal and editor names and rewrite the paragraph explaining why you chose the journal, since it should refer to that journal’s own recent papers.
