A cover letter is a short, personalized letter that goes with your resume and explains why you fit one specific job. It should run no longer than a page, use three to five short paragraphs, and add context your resume cannot: why this employer, why this role, and what you have done that proves you can do it. For remote and work-from-anywhere roles, it also tells the employer where you are, which time zone you work in, and how you operate without supervision.
TL;DR
-
Send a cover letter when the posting asks for one, and consider one when it is optional, especially for competitive roles.
-
Keep it to one page and three to five short paragraphs. Do not repeat your resume.
-
Tailor every letter to the role, use the employer’s own wording, and address a named person when you can.
-
For remote jobs, state your location, time zone, and how you work independently.
-
Use AI for a first draft only. Rewrite it so the examples and voice are yours.
What a cover letter does
Your resume lists what you did. Your cover letter connects it to the job in front of you. Harvard’s career services describes it as a writing sample and part of the screening process that can show your writing skills and strengths and improve your chances of an interview.
That matters most in remote hiring. Employers who work asynchronously read a lot of written communication, and your letter is often the first sample they see.
Do you need one?
Use a simple rule:
-
The posting requires one. Send it. Skipping it usually means your application is incomplete.
-
The posting says not to send one. Follow the instruction. Following directions is part of the test.
-
The posting says nothing. Send a strong, tailored letter if the role matters to you. A rushed, generic letter can hurt more than it helps, so if you cannot make it specific, do not pad your application with it.
In the UK, the government’s National Careers Service advises that you always include a cover letter when applying with a CV. US employers vary more, so read each posting.
How to structure a cover letter
The format is standard, and plain is better. A university career office in Germany recommends three to five short paragraphs separated by blank lines, left-aligned, in the same font and size as your resume. Harvard adds that the letter should be concise, factual, and limited to a single page.
Here is a layout that works:
| Part | What goes in it | Length |
|---|---|---|
| Header | Your name, email, phone, city and time zone, the date | 3 to 4 lines |
| Greeting | The hiring manager’s name if you can find it | 1 line |
| Opening | The role, why this company, and your strongest relevant point | 2 to 3 sentences |
| Body (1 to 2 paragraphs) | Specific examples that match the job’s main requirements | 4 to 6 sentences each |
| Closing | A short thank-you and a clear next step | 2 to 3 sentences |
| Sign-off | “Sincerely,” and your name | 2 lines |
Greeting
Address a specific person where possible. Check the job post, the company’s team page, or LinkedIn. If you find no name, “Dear Hiring Team” is better than a stiff “To Whom It May Concern.”
Opening
Skip the line that says you are writing to apply. The employer knows. Start with the reason you are a fit: a result you delivered, a problem you solved, or a specific thing about the company that drew you in.
Body
Pick two or three requirements from the posting and answer each with one concrete example. Use numbers where you honestly have them. Harvard’s advice is to tell a story about your experience with relevant, specific examples rather than repeat your resume.
Closing
Restate your interest in one sentence and say you would welcome a conversation. Do not apologize or hedge.
How to tailor it to the role
Tailoring is the difference between a letter that gets read and one that gets skimmed. Do this in about 20 minutes:
-
Read the posting twice. Highlight the three or four duties that appear most often.
-
Research the organization. Read its about page, recent announcements, and any public handbook. Harvard’s guidance is to research the organization and address how your skills meet its needs.
-
Borrow the vocabulary. NYU Abu Dhabi’s career center advises using the company’s language and keywords from the job description. If the posting says “customer onboarding,” do not call it “client setup.”
-
Match each requirement with proof. One requirement, one example.
If your resume itself needs the same treatment, our remote resume guide covers it, and the article on adding two remote proof bullets shows how to make remote experience visible fast. For help matching your application to current hiring patterns, a guide on aligning your CV with market trends is a useful companion.
If you have little experience
Lead with projects, coursework, volunteer work, freelance gigs, or self-taught skills, and describe what you did and what changed because of it. A walkthrough on writing a cover letter with no experience shows how to build the letter around evidence instead of job titles.
What to add for a remote or work-from-anywhere job
Remote roles draw applicants from everywhere, so your letter has to answer practical questions before the recruiter asks them. Utah State University’s remote work program advises you to communicate your location, time zone, and ability to work independently. It also notes that broader competition makes tailoring more important.
In practice, cover these points in a sentence or two each:
-
Where you are and where you will be. Give your current location and time zone. If you travel, say how you keep core hours. Be accurate: some employers can only hire in certain countries, and a role labeled “remote” may not mean “anywhere.”
-
How you work without supervision. Name a real example: a project you ran across time zones, a written process you created, a tool you used to keep a team aligned.
-
How you communicate in writing. Your letter is the proof. Keep it clear and specific.
-
Your overlap with the team. If the posting names working hours, say whether you can meet them.
Before you submit, run through our remote job application checklist to confirm location rules, time-zone expectations, and paperwork. If you plan to work from another country than your employer’s, read how to negotiate working abroad as a remote employee before you promise anything in writing.
Five mistakes that sink cover letters
-
Sending the same letter everywhere. Harvard lists untailored letters first among the errors to avoid.
-
Repeating your resume. The letter should add a story or context, not restate your job history.
-
Writing to nobody. Find a name when you can.
-
Running past one page. Harvard’s guidance is a single page.
-
Passive, stiff phrasing. NYU Abu Dhabi recommends the active voice and a professional tone that matches the company’s own.
Two more worth checking: typos, and a file name that does not include your name.
Using ChatGPT to write a cover letter
Yes, an AI assistant can help, as a drafting partner and not an author. It is useful for turning your notes into a first draft, tightening long sentences, and suggesting a structure. It cannot know what you actually did, and it tends to produce generic phrasing that recruiters recognize.
A safer workflow:
-
Paste in the job description and your own bullet points, not just your resume.
-
Ask for a draft of three to five short paragraphs under one page.
-
Replace every vague claim with a real example and number from your own work.
-
Remove any claim you did not make. AI can invent skills, employers, and results.
-
Read it aloud. If it does not sound like you, rewrite it.
-
Check the company name, the role title, and the contact name before sending.
FAQ
What do I write in a cover letter?
Open with why you fit the role and the company. Then give two or three specific examples that match the posting’s main requirements, and close with a clear, polite next step. Keep it to one page.
How long should a cover letter be?
One page, in three to five short paragraphs. Many career offices recommend this, including Harvard’s. If a paragraph does not support your fit for the job, cut it.
Do I need a new cover letter for every application?
Yes, at least a customized version. You can reuse your strongest examples, but the opening, the company-specific reasons, and the keywords should change each time. A generic letter can be worse than none.
What should a remote cover letter include?
Everything a normal one does, plus your location, time zone, and a concrete example of working independently. If the role has location or hours requirements, address them directly.
Can ChatGPT write my cover letter?
It can produce a draft, but you should edit it heavily. Add your own examples, delete anything untrue, and make sure the tone matches you and the employer.
