Writing a cover letter for journal submission should not take more than 30 minutes. If it's taking longer, you are overthinking it.

Editors read hundreds of cover letters. The ones that work all do the same thing: lead with the finding, explain why it matters, explain why this journal. Three things. That is it.

The ones that fail do the opposite: open with background, bury the finding, and close with generic journal praise that could apply to any journal.

Below are five complete, filled-in templates for different journal tiers and fields. Pick the one closest to your situation, swap in your details, and you are done.

What a journal cover letter must include

Every journal cover letter needs these five elements:

1. Your finding in one sentence - the main result, stated plainly, not your topic or background
2. Why it matters - 2-3 sentences with at least one number (sample size, effect size, p-value)
3. Why this journal - name a recent paper from this journal and connect it directly to your work
4. Competing interests and logistics - conflicts of interest, data availability, trial registration if applicable
5. Author approval - confirm all authors have approved the submission

That is the complete list. Everything else is optional. A cover letter that hits all five points in under 300 words will outperform a 600-word letter that buries the finding in paragraph three.

Six templates: jump to yours

• Template 1: High-impact multidisciplinary journal (Nature Portfolio, Science family, Cell Press upper tier)
• Template 2: Clinical/medical journal (NEJM, Lancet, JAMA, BMJ)
• Template 3: Mid-tier specialist journal (IF 5-15, field-specific)
• Template 4: Open-access journal (PLOS ONE, Scientific Reports, Frontiers)
• Template 5: Resubmission after invited revision
• Template 6: Resubmitting a rejected paper to a new journal

Template 1: High-impact multidisciplinary journal ([Nature](/journals/nature), [Cell](/journals/cell), [Science](/journals/science))

Use for: Nature Communications, Science Advances, PNAS, Cell Reports, eLife

Dear Editor,

We show that FOXO3a nuclear localization is driven by intracellular calcium flux, not AKT phosphorylation as previously assumed. This finding reframes two decades of work on FOXO3a-mediated apoptosis resistance in solid tumors.

Using live-cell calcium imaging in 12 primary tumor cell lines paired with single-cell transcriptomics, we demonstrate that calcium-dependent FOXO3a activation is necessary and sufficient for doxorubicin resistance. Blocking calcium entry with FDA-approved L-type channel blockers sensitized resistant tumor cells to doxorubicin in both cell culture and mouse xenograft models.

This work builds directly on Zhang et al. (2024, Nature Communications) who identified FOXO3a as a resistance marker but could not explain the activation mechanism. We resolve that question and point to a clinically actionable intervention. We believe this manuscript will interest the broad readership of Nature Communications given its mechanistic depth and immediate translational relevance.

All authors have approved this submission. We have no competing interests. Data and code are deposited at [repository DOI].

Sincerely,

[Name, Institution, email]

Why this works:

• First sentence states the finding and names the prior assumption it overturns
• Second paragraph gives mechanism, evidence type, and animal model
• Third paragraph names a specific recent paper from this journal and connects directly to it
• No filler, no throat-clearing, no "we are pleased to submit"

Template 2: Clinical/medical journal ([NEJM](/journals/nejm), [JAMA](/journals/jama), [BMJ](/journals/bmj))

Use for: NEJM, Lancet, JAMA, BMJ, Annals of Internal Medicine, Circulation

Dear Editor,

We report a randomized controlled trial demonstrating that a 12-week structured exercise intervention reduces 90-day hospital readmission rates by 34% in patients with moderate-to-severe heart failure (hazard ratio 0.66, 95% CI 0.51-0.85, p=0.001).

Our trial enrolled 847 patients across 14 centers. The intervention is low-cost, scalable, and deliverable by non-specialist staff without specialized equipment. At current US heart failure readmission rates, widespread adoption could prevent approximately 180,000 readmissions annually.

Despite strong evidence for exercise in stable heart failure, benefit in patients with recent decompensation has been uncertain. We recruited exclusively within 30 days of discharge, filling a gap that prior trials: including HF-ACTION: explicitly excluded. We believe this evidence gap is directly relevant to The Lancet's clinical readership.

All authors have approved this submission. The trial is registered at ClinicalTrials.gov (NCT04XXXXXX). We have no competing interests.

Sincerely,

[Name, Institution, email]

Why this works:

• Clinical editors want numbers in sentence one: the finding is fully quantified
• Paragraph 2 addresses scalability and public health impact, which clinical journals weigh heavily
• The gap versus named prior trials is explicit, not vague
• Trial registration is stated up front (required for clinical work; editors check)

Template 3: Mid-tier specialist journal ([Nature Communications](/journals/nature-communications), [PNAS](/journals/pnas))

Use for: journals with IF 5-15 in your specific field

Dear Dr. [Editor name],

We submit our manuscript describing a novel mechanism by which Pseudomonas aeruginosa biofilms evade neutrophil extracellular traps (NETs) via phenazine-mediated DNA degradation. This mechanism has not previously been described and may explain why chronic P. aeruginosa infections persist despite intact innate immune responses.

Using confocal microscopy, genetic knockouts, and a murine lung infection model, we show that phenazine production by biofilm-embedded P. aeruginosa degrades NET DNA within 4 hours of contact, preventing NET-mediated bacterial killing. Phenazine-deficient mutants were 8-fold more susceptible to NET killing than wild-type strains.

The Journal of Infectious Diseases has recently published strong work on biofilm immune evasion (Smith et al. 2024; Chen et al. 2023), and we believe this mechanistic paper adds directly to that body of work.

All authors have approved this submission. The authors declare no competing interests.

Sincerely,

[Name, Institution, email]

Why this works:

• Specialist editors do not need broad significance explained: they know the field
• Technical terminology is appropriate and expected
• Two specific recent papers from this journal are cited (shows you actually read it)
• Shorter than Template 1: specialist journals do not need the same scope justification

Template 4: Open-access journal ([eLife](/journals/elife), [PLOS ONE](/journals/plos-one), [Scientific Reports](/journals/scientific-reports))

Use for: PLOS ONE, Scientific Reports, BMJ Open, Frontiers journals

Dear Editor,

We submit a methodological validation study of a machine learning algorithm for automated grading of diabetic retinopathy severity from fundus photographs. The algorithm achieves 94.2% sensitivity and 91.8% specificity against a panel of three board-certified ophthalmologists (n=2,847 images from three independent test sets).

The algorithm is trained on publicly available datasets and released under MIT license at [GitHub URL]. Validation includes images from low-resource clinical settings in sub-Saharan Africa, addressing a gap in most published retinopathy AI tools which are validated only on Western clinical data.

We submit to PLOS ONE because this work represents a technically sound, reproducible contribution with clear clinical utility. The study is designed to be replicated. All data and code are available as described in the data availability statement.

Ethics approval documentation is included in the submission.

Sincerely,

[Name, Institution, email]

Why this works:

• Leads with performance numbers, which is what reviewers will check first
• Explicitly invokes PLOS ONE's soundness-only review criteria ("technically sound, reproducible")
• Addresses data availability proactively: PLOS ONE rejects papers without this
• Does not claim novelty it doesn't have

Template 5: Resubmission after desk rejection ([see our guide on what to do after desk rejection](/blog/what-to-do-after-desk-rejection))

Only use this if the editor explicitly invited resubmission. A form rejection with no invitation means submit elsewhere.

Dear Dr. [Editor name],

We resubmit our manuscript (originally submitted as MS-XXXXX) with substantial revisions in response to your editorial assessment.

We have [describe changes specifically: e.g., added two in vivo validation experiments using the xenograft model you suggested, restructured the main claims to focus on the calcium mechanism rather than the downstream apoptosis pathway, and removed the clinical extrapolations that went beyond our data].

The core finding is unchanged: [one sentence restating the result]. We believe the revised manuscript now addresses the concerns you identified about [specific issue] and is appropriate for [Journal Name].

We have not submitted this manuscript elsewhere during the revision period. All authors have approved this resubmission.

Sincerely,

[Name]

Important: Be specific about what changed. "We have addressed the reviewer comments" without details signals to editors that you have not taken the feedback seriously.

Template 6: Resubmitting a rejected paper to a new journal {#template-6}

Use for: any new submission after a rejection elsewhere. Do NOT mention the previous rejection unless the new journal explicitly asks.

Dear Dr. [Editor name],

We submit our manuscript describing [one-sentence finding]. [Two to three sentences of significance, with numbers.]

[Journal fit paragraph: name a recent paper from this journal, explain the connection to your work.]

All authors have approved this submission. [Competing interests. Data availability.]

Sincerely,

[Name, Institution, email]

The key difference from a fresh submission: There isn't one: at least not in the letter itself. You're not obligated to disclose a previous rejection, and doing so unprompted can hurt you. Just write the best possible cover letter for this journal.

What to do with prior reviewer feedback: If the previous reviewer comments helped you improve the paper, those improvements will show in the manuscript. You don't need to explain their origin.

If a journal specifically asks whether this was submitted elsewhere: Be honest. Say where it was submitted and why you're now targeting this journal. Some journals ask routinely; a truthful answer is fine and won't automatically count against you.

When reviews transfer (e.g., Science to Science Advances): This is different. If the editor offers a transfer, the original reviews come with the manuscript and you'll need to address them. In this case, your cover letter should briefly acknowledge the transfer and note that you've revised in response to the previous review.

What NOT to include in a cover letter

Editors have read thousands of cover letters. These patterns signal that you haven't thought carefully about what they need:

Summarizing your abstract verbatim. The editor will read your abstract. Don't repeat it. Your cover letter should contain information the abstract doesn't: specifically, why this journal and why now.

Vague "significant contribution" language. "This paper makes an important contribution to the field" tells the editor nothing. Every author thinks their paper is important. Show the significance with specifics: a number, a gap you're filling, a prior paper you're building on.

Generic journal praise. "We chose [Journal Name] because of its high standards and wide readership" could describe any journal. Find something specific: a recent paper in this journal that your work connects to, or a methodological focus that matches yours.

Listing your co-authors' credentials. The editor doesn't care that three of your co-authors are full professors. They care what you found. The author list and affiliations are on the title page.

Going over 400 words. At 400 words, editors are still reading. At 600, they're skimming. There's almost nothing you need to say in a cover letter that can't be said in 300-350 words.

Asking the editor to consider the paper favorably. "We hope you will consider this paper for publication" is filler. Of course you do: that's why you submitted. Cut it.

Burying your finding. If your main result appears for the first time in paragraph three, you've already lost the editor's attention. The finding goes in sentence one.

The skeleton (when none of the above fits exactly)

Dear [Editor name or "Editor"],

[FINDING SENTENCE: We show that / We demonstrate that / We report that + your main result in one sentence]

[SIGNIFICANCE: 2-3 sentences. What does this explain, enable, or change? Include numbers. End with the broadest relevant implication.]

[JOURNAL FIT: Name a specific recent paper from this journal. Explain the connection. Say why this journal's readers will care.]

[LOGISTICS: Competing interests. Data availability. Trial registration if applicable.]

Sincerely, [Name, Institution, email]

Target length: 200-350 words. Never more than 400.

About "we are pleased to submit our manuscript entitled..."

This is the most common opening in academic cover letters. Editors have read it thousands of times. It tells them nothing about your paper.

Compare:

Version A (what most researchers write):

"We are pleased to submit our manuscript entitled 'Calcium-dependent FOXO3a activation drives doxorubicin resistance in solid tumors' for consideration in Nature Communications."

Version B (what gets read):

"We show that FOXO3a nuclear localization is driven by intracellular calcium flux, not AKT phosphorylation as previously assumed."

Version B gives the editor a reason to keep reading in the first 15 words. Version A makes them wait until after the title to learn anything.

Other common openings to replace:

The first sentence is your best shot at making an editor stop and read the second one. Use it.

Competing interests and logistics

Every cover letter needs this, whether required or not:

No conflicts: "All authors declare no competing interests."

Funding: "This work was funded by [Grant]. The funders had no role in study design or the decision to publish."

Industry ties: "[Author X] has received consulting fees from [Company A]. [Author Y] holds equity in [Company B]. All other authors declare no competing interests."

Do not skip this. Editors check, and omitting it looks careless or evasive.

Suggested reviewers: how to do it right

Many journals ask for suggested reviewers in the cover letter or submission form. Most authors treat this as a box to tick. That's a mistake: suggested reviewers who actually get assigned tend to give faster, more informed, and more constructive reviews.

Who to suggest:

• People who have published directly on your topic in the last 3-5 years, but are not current or recent collaborators (within 5 years)
• Mid-career researchers are better choices than famous senior figures: they're more likely to accept the invitation and give a thorough review
• Include people from different institutions and, if relevant, different countries
• Aim for 3-5 names

What information to include:

• Full name
• Institution and department
• Email address (this is what editors actually need: don't make them look it up)
• Optional: one sentence on why they're qualified ("Published foundational work on X mechanism in 2023")

Example format:

Suggested reviewers:
- Dr. Jane Smith, Department of Molecular Biology, University of X (j.smith@university.edu): Published closely related work on [topic] in Nature Communications (2024)
- Dr. Ahmed Hassan, Institute for [Field], [University] (a.hassan@uni.edu)

Who NOT to suggest:

• Your PhD supervisor, postdoc mentor, or anyone you've co-authored with recently
• People at the same institution as any of your co-authors
• Anyone you're currently collaborating with on another project
• Very famous researchers who are likely overloaded with requests

Opposed reviewers: Most journals also let you request exclusions for people with conflicts of interest. Use this option for direct competitors who have made hostile statements about your work, not just anyone who might be critical. A reasonable exclusion request signals you understand the process; an unreasonable one signals paranoia.

Format: "We request that [Name] be excluded as a reviewer due to [conflict, e.g., direct competition on an overlapping project currently in review]."

Before you submit: final checklist

• [ ] First sentence states your finding, not your topic
• [ ] At least one number (sample size, effect size, p-value, or equivalent)
• [ ] You named a specific paper from this journal, not the journal itself
• [ ] Competing interests declared
• [ ] Data availability addressed
• [ ] Under 400 words total
• [ ] Editor addressed by name if you know it
• [ ] No "we are pleased to submit"

The Bottom Line

A cover letter doesn't need to be long or elaborate. It needs to answer two questions for the editor: is this paper in scope, and does it meet the journal's significance threshold? If your cover letter does that clearly and honestly, it's doing its job.
