Ask ten recruiters whether cover letters matter and you will get ten different answers, which tells you something: they are optional in effect, even when a form requires one. Plenty are never opened.
That is not an argument for skipping them. It is an argument for understanding what a cover letter is for. A resume is a record of what you have done. A cover letter answers the question the record cannot: why this job, and why you for it. When the answer is non-obvious — a career change, a gap, a slight mismatch, a company you specifically want — the letter does work nothing else can.
When it is worth writing
| Situation | Verdict |
|---|---|
| Career change or industry switch | Write one. This is where letters earn their keep. |
| Employment gap or unusual history | Write one. A neutral line here beats speculation. |
| A company you specifically want | Write one, and make it specific to them. |
| Small company or direct-to-founder | Write one. It is often read properly. |
| Strong, obvious match at a large employer | Optional. A short note is enough. |
| High-volume applications through a portal | Skip, or reuse a light template. |
| Explicitly requested in the posting | Write one, always. |
The four-paragraph structure
Under 300 words, four paragraphs, one page with room to spare. Anything longer is competing with your resume for the reader's remaining attention.
- 1. The hook — why this role, specifically
One or two sentences naming the role and the concrete reason you are applying. Not “I am excited about this opportunity” but something only someone who read the posting could write: the product, the problem, the stage the team is at.
- 2. The proof — your single strongest relevant result
Take the achievement closest to what the posting emphasises and tell it in three or four sentences: the situation, what you did, what changed. This is the paragraph that earns the interview, and it is the one most letters skip.
- 3. The bridge — why you fit this company
Connect your experience to their specific context. Team size, stage, industry, constraint. This is also where a career change, gap, or relocation gets one calm sentence of explanation.
- 4. The close — a clear, low-friction ask
One sentence. “I would welcome the chance to talk about how I would approach the first 90 days.” No apologies, no “thank you for your time and consideration”.
Openings
First sentences
Works
- I am applying for the Senior Analyst role because the posting describes the exact problem I spent last year on: reporting that three teams disagreed with.
- I have spent six years on payments infrastructure, and the reliability framing in your job description is unusual enough that I wanted to write properly.
- I am a nurse of nine years moving into clinical informatics, and I led the EHR rollout that this role would own next.
Avoid
- I am writing to express my strong interest in the Senior Analyst position at your esteemed organisation.
- Please find attached my resume for your kind consideration regarding the above-mentioned vacancy.
- I believe I would be a great fit for this role and a valuable addition to your team.
The weak openings share a property: they could have been sent to any employer on earth. The strong ones could only have been written by someone who read the posting and has something specific to say. That contrast is the whole game.
What to cut
- Restatements of your resume. If a sentence lists jobs and dates, delete it. The reader has the resume.
- “As you can see from my attached CV.” They can see. Say something new instead.
- Adjectives about yourself. Hard-working, passionate, detail-oriented. Unverifiable, and everyone claims them.
- Flattery about the company. “Industry-leading”, “world-class”. It reads as filler and tells them nothing.
- Explaining what the job involves. They wrote the posting.
- Salary expectations, unless the posting asks. It shifts the conversation before you have leverage.
- “To Whom It May Concern.” Find a name; if you cannot, “Dear Hiring Team” is fine.
Cutting these usually halves the draft, and what remains is the part worth reading.
Handling the awkward things
A cover letter is the right place to address something a recruiter would otherwise guess about. One sentence, factual, no apology, then move on.
| Situation | One line that works |
|---|---|
| Employment gap | I took eighteen months out for caregiving and returned to contract work in January. |
| Career change | I am moving from operations into analytics, having spent the last two years building the reporting my own team ran on. |
| Relocating | I am relocating to Manchester in September and am looking for a role there rather than remote. |
| Overqualified on paper | This is a step back in scope by choice — I want to be closer to the product than my last role allowed. |
| Missing one requirement | I have not used Snowflake, though I have four years in BigQuery and expect the transition to be short. |
Format and sending
- Under 300 words, four short paragraphs, generous white space.
- Same font and header as your resume — it reads as one coherent application.
- PDF, named
Firstname-Lastname-Cover-Letter.pdf. - Address a person where you can find one. The hiring manager beats the recruiter beats “Hiring Team”.
- If the form has a text box rather than an upload, paste the letter without the address block and keep it even shorter.
- When emailing directly, put the letter in the email body and attach only the resume. Nobody opens two attachments.
A reusable skeleton
Keep one template with three slots to fill per application — the specific reason, the closest achievement, and the company connection. That turns each letter into a 20-minute job instead of a blank page.
Dear [name], I am applying for [role] because [specific, non-generic reason drawn from the posting]. At [company] I [achievement with a number, chosen to match what the posting emphasises]. [One sentence on how you did it.] What draws me to [their company] specifically is [their stage, product, constraint, or approach]. [If needed: one neutral sentence on a gap, change, or relocation.] I would welcome the chance to talk about [something concrete — the first 90 days, a problem in the posting]. [Your name]
Fill the three bracketed slots per application; the rest stays
Then read it once aloud. If any sentence would survive unchanged in a letter to a different company, it is not doing anything — replace it or cut it. The same discipline that makes resume bullets work makes cover letters work.
Frequently asked questions
Are cover letters still necessary in 2026?
Not universally — many are never opened, particularly at large employers using application portals. They remain worth writing when the fit is not obvious from your resume: career changes, employment gaps, relocations, small companies where a human reads every application, and any posting that explicitly asks for one.
How long should a cover letter be?
Under 300 words, in four short paragraphs. A longer letter competes with your resume for the reader's attention and is more likely to be skimmed or skipped entirely.
What should the first line of a cover letter say?
The role you are applying for and one specific reason, drawn from the posting, that only someone who read it could write. Avoid “I am writing to express my interest” — it uses a full sentence to say nothing and signals a template.
Should I explain an employment gap in my cover letter?
Yes, in one neutral sentence — caregiving, study, health, contract search — and then move on. Naming it removes the ambiguity that makes recruiters hesitate. Explaining it at length makes it the most memorable part of your application.
Can I use the same cover letter for multiple jobs?
Use the same structure, not the same text. Keep a skeleton with three slots — the specific reason for this role, your closest relevant achievement, and the connection to this company — and fill them per application. That takes about twenty minutes and reads nothing like a template.
