When you need to submit a cover letter with your manuscript, you'll probably write it just before submission. Like many other authors, you may find yourself wondering what to write and taking longer than you expected, causing last-minute delays and stress.
To help you write effective cover letters—and to write them quickly and easily—in this article we offer some tips on layout and appropriate wording. Also, you can download our template cover letter (Word file) to help you save time writing and help you remember to include standard author statements and other information commonly required by journals.
If you are submitting a revised paper to the same journal, note that the response letter to the reviewers is different from the cover letter used at initial submission. You can find tips and a template on writing effective response letters to the reviewers in our previous article.
Many journals require a cover letter and state this in their guidelines for authors (alternatively known as author guidelines, information for authors, guide for authors, guidelines for papers, submission guide, etc.). For some journals, a cover letter is optional or may not be not required, but it's probably a good idea to include one.
Cover letters can be helpful to journal staff in the following ways.
1. Cover letters that include standard statements required by the journal allow the journal staff to quickly confirm that the authors have (or say they have) followed certain ethical research and publishing practices.
These statements assert that the authors followed standard practices, which may include (i) adhering to ethical guidelines for research involving humans (Declaration of Helsinki), involving animals (ARRIVE guidelines), or falling under institutional guidelines; (ii) obtaining ethics approval from institutional review boards or ethics committees; (iii) obtaining informed consent or assent from participants; (iv) complying with authorship criteria (e.g., ICMJE criteria); (v) confirming no duplicate submissions have been made; and (vi) recommending reviewers for your paper, which may include specifying peers that you prefer not be contacted.
2. Cover letters can summarize your manuscript quickly for the journal editor, highlighting your most important findings and their implications to show why your manuscript would be of interest.
Some journals, such as Nature, state that while a cover letter is optional, it provides "an excellent opportunity to briefly discuss the importance of the submitted work and why it is appropriate for the journal." Some publishers, such as Springer, recommend that you write a cover letter to help "sell" your manuscript to the journal editor.
3. Cover letters that contain all of the information required by the journal (as stated in the guideline for authors) can indicate that you have spent time carefully formatting the manuscript to fit the journal's style. This creates a good first impression. Addressing the letter to a named editor at the journal also shows that you took the time to write your letter (and by extension, your manuscript) with care and considered the fit with the journal beyond just impact factor.
Cover letters should be short—preferably no more than 1 page—and they often use single line spacing. The content can be broadly divided into six sections:
Let's look at some tips for each section. And don't forget to download the template, which shows these tips already in place.

Although the cover letter is not, strictly speaking, a part of your manuscript, it can affect how your submission is perceived by the journal editor. A cover letter that is tailored to the journal, introduces your work persuasively, and is free from spelling and grammatical errors can help prime the editor to view your submission positively before he or she even looks over your manuscript.
