A cover letter is not a summary of your resume in paragraph form. It exists to do the one thing a resume structurally cannot: connect your specific experience to this employer's specific problem, in your own voice. When it is read at all, it is usually read after the resume has already interested someone, and it decides whether that interest turns into a call.
Does anyone still read them?
Inconsistently, which is the honest answer. Large-volume recruiting often skips them. Hiring managers at smaller organisations frequently read every one. Any role involving writing, client contact or judgement tends to get read closely, because the letter is a work sample.
The practical conclusion: write one whenever the field exists, but do not spend an hour on it. Twenty to thirty focused minutes on a letter that says something specific beats a polished template that says nothing. If the application makes it optional and you have nothing particular to say about that employer, that is a signal you should be applying somewhere else.
The structure
Four paragraphs, 250 to 400 words, one page with room to spare. Anything longer is not being read to the end.
- The opening. Which role, and one specific reason you are writing to them rather than anyone.
- The proof. One or two concrete stories showing you have done the thing they need done.
- The fit. Why this organisation, demonstrated with evidence you have looked into it.
- The close. A short, confident sign-off.
Paragraph one: the opening
Delete "I am writing to apply for the position of X as advertised on your website." It uses a whole sentence to convey information the system already has.
Weak: "I am writing to express my interest in the Marketing Manager role at Northfield Group. I believe my skills and experience make me an excellent candidate for this position."
Stronger: "Your posting for a Marketing Manager mentions rebuilding the demand generation function after two years of channel-led growth. I did exactly that at Halberd Software last year, taking email from an afterthought to the largest single source of qualified pipeline."
The second version proves in two sentences that you read the posting and have relevant experience. That is the entire job of the opening. If you have a referral, use it here and name the person: an internal name is the strongest opening available.
Paragraph two: the proof
Pick the one or two requirements the posting emphasises most and tell a short story against each. Situation, what you did, what resulted. Two or three sentences per story.
Weak: "I have excellent project management skills and a proven ability to deliver results under pressure while working collaboratively with stakeholders at all levels."
Stronger: "I inherited a fifteen-site network refresh that was four months behind schedule and over budget. I renegotiated the vendor sequencing, moved to a rolling regional rollout instead of a single cutover, and delivered the remaining twelve sites on the revised date with no unplanned downtime. The approach is now the standard template for that client's rollouts."
Do not restate resume bullets. Give the context and the reasoning that would not fit on the resume. The letter is where you get to explain why you made a decision, which is what a hiring manager is actually assessing.
Paragraph three: why this organisation
This is the paragraph that separates a tailored letter from a template, and the one most people skip or fill with flattery.
Weak: "I have long admired your company's reputation as an industry leader and its commitment to innovation and excellence."
Stronger: "I have followed your move into the mid-market tier since the pricing change last spring. Having spent three years selling a product that was repositioned in the same direction, I know the awkward stretch where enterprise messaging still hangs around the smaller segment, and I would like to work on that problem here."
Sources for a genuine version of this paragraph: the company's own blog or engineering posts, recent funding or acquisition news, a product change you noticed as a user, something the hiring manager has published, the way the posting is written. Fifteen minutes of reading is enough.
If you cannot write this paragraph honestly, the letter will read as generic no matter how good the rest is.
Paragraph four: the close
Short. No begging, no presumption.
Too passive: "Thank you for taking the time to consider my application. I hope to hear from you at your earliest convenience."
Too pushy: "I will call your office on Tuesday to arrange an interview."
About right: "I would welcome the chance to talk through how I would approach the first ninety days in this role. I am available at short notice and happy to work around your schedule."
Sign off with "Yours sincerely" if you have a named recipient, "Yours faithfully" if you do not, or "Best regards", which is safe in either case and standard in most markets.
Addressing it
Find the name. The posting, the company's team page, LinkedIn searched by company and job function, or the recruiter who posted the vacancy. "Dear Sarah Whitfield" or "Dear Ms Whitfield" both work; match the formality of the industry.
If you genuinely cannot find a name, use "Dear Hiring Manager". Never "To Whom It May Concern", which reads as a letter written for nobody, and never "Dear Sir/Madam" in markets where it has fallen out of use.
Format
- Match the visual style to your resume: same font, same header with your contact details. It looks like a considered set rather than two separate documents.
- Include the date and the company name and address if you are producing a formal letter; skip them if you are pasting into a text field.
- Submit as PDF unless asked otherwise, named clearly with your name and the role.
- If the application has a message box rather than an upload, paste the letter body in without the formal letterhead. Keep it shorter still, around 200 words.
Our cover letter builder pairs the layout to whichever resume template you are using, which removes the fiddly part.
Three situations that need different handling
Career change
Address it directly in paragraph one rather than hoping nobody notices. State the target role, name the transferable evidence, and be concrete about what you have done to close the gap.
"After seven years teaching secondary science I moved into corporate learning design, and I have spent the last two years building blended programmes for adult learners. The compliance course I designed last year is now used by 900 staff across three sites. Classroom teaching turns out to be excellent preparation for the part of this job that involves getting people to engage with material they did not choose."
Employment gap
One sentence, factual, then move on. "I took eighteen months out for family caregiving and returned to consulting work in March." Do not apologise and do not over-explain. Length signals discomfort.
Under-qualified on paper
If you meet most of the requirements but not all, name the gap once and counterweight it, rather than pretending it is not there.
"I have four years rather than the five you have specified, and no direct experience in insurance. What I do have is three years of building compliance-bound reporting in a similarly regulated environment, and a track record of getting productive in a new domain quickly."
Do not do this for a gap you cannot bridge. If the role requires a licence you do not hold, no letter will fix that.
Things to cut
- "I believe" and "I feel". Hedging weakens every sentence it appears in. "I led the migration" is stronger than "I believe my experience leading the migration would be valuable".
- Restating your whole resume. They already have it.
- Salary discussion, unless the posting explicitly asks for expectations.
- Explaining why you are leaving your current job, particularly anything negative about the employer.
- Adjective stacking. "Dynamic, results-driven, passionate self-starter" is four words that mean nothing.
- Anything the reader cannot act on. Every sentence should either prove something or ask for something.
Speculative letters, when there is no vacancy
Writing to an organisation with no advertised role is worth doing in small industries and for senior positions, where hiring is often reactive. The structure changes: instead of matching a posting, you are proposing a problem you could solve.
Lead with the observation rather than yourself. "You have opened two sites this year and your careers page shows no one owning fulfilment operations centrally. That is usually the point where per-site processes start contradicting each other." Then give your evidence in two or three sentences, and close by asking for a short conversation rather than a job. Twenty minutes is an easy thing to say yes to; a job is not.
Send it to a named person with hiring authority, not a general inbox, and follow up once after a fortnight. The hit rate is low, but the responses you do get come with almost no competition attached.
Email applications and short message fields
When you are applying by email, the letter goes in the body of the message rather than as a second attachment, and the subject line matters. "Operations Manager application - James Okafor" is clear and searchable. Do not write "Job application" or leave it blank.
Keep the emailed version shorter than a formal letter, around 200 words, and put the strongest sentence first because the preview pane shows the opening line. Attach the resume as a PDF, name it properly, and check it is actually attached before sending, which is a mistake people make more often under pressure than they expect.
Where an application form gives you a small free-text box instead of an upload, treat it as the letter and write three tight paragraphs. Do not write "please see attached", and do not paste a formal letterhead with dates and addresses into a text field, which looks like a document dropped in the wrong place.
A worked example, end to end
"Dear Ms Whitfield,
Your posting for an Operations Manager describes a warehouse running at 96 per cent pick accuracy with a peak season approaching. I spent the last two years fixing the same problem at Kestrel Logistics, and took accuracy from 96.4 to 99.1 per cent without adding headcount.
The gains came from two changes. I re-slotted the pick faces by velocity rather than by product family, which cut average travel per order by roughly a third, and I moved training from a one-off induction to a fortnightly fifteen-minute session on the floor. Errors fell fastest among staff in their first three months, which is where most of them had been coming from. We held the improvement through the following peak with a 40 per cent volume increase.
I have been following your move to a single national distribution centre. Consolidation of that kind usually exposes exactly this problem: processes that worked at two smaller sites break when the pick face triples. That transition is the part of the job I would most like to work on.
I would welcome the chance to talk through how I would approach the first ninety days here. I am available at short notice.
Best regards,
James Okafor"
