Most people spend hours polishing a CV and then throw a cover letter together in ten minutes. That is a mistake. A recruiter often reads the letter first, and it quietly decides whether your CV gets a proper look at all. Knowing what to include in a cover letter, and what to leave out, is one of the cheapest ways to improve your odds in a crowded job market.
Start with the job, not with yourself
Plenty of letters open with a line like "I am writing to apply for the position advertised on your website." It is not wrong, but it wastes the most valuable sentence you have. The reader already knows you are applying. Open instead with something that shows you understand what the role needs. A single sentence about the company's recent work, or about the specific problem the job exists to solve, tells the reader you have paid attention. That first line buys you the next paragraph.
What to include in a cover letter
Strip it back and a strong letter contains only a few things. First, a short statement of who you are and the role you want. Second, two or three concrete examples that match your experience to what the advert asks for. If the posting mentions managing budgets, name a budget you managed and what came of it. Third, a sentence on why this employer specifically, rather than employers in general. Everything else is padding.
Notice what is not on that list: your entire work history, your school grades, or a paragraph insisting that you are a hard worker. The CV carries the full record. The letter argues the case. If you are trying to stand out, a concrete skill carries far more weight than adjectives. Something like learning a new language can lift an application in fields where clients and colleagues are spread across borders.
How to address a cover letter
The safest approach is to find the name of the person who will actually read it. A quick look at the company site or a professional network usually turns up the hiring manager or team lead. "Dear Ms Ahmed" reads far better than "To whom it may concern," which signals that you did not check. If you genuinely cannot find a name, "Dear Hiring Manager" is fine. Try to avoid "Dear Sir or Madam" where you can, because it feels dated. And if you are applying for a role in another country, remember that your CV and letter may need professional document translation before they carry the same weight with a local employer.
How long should a cover letter be
Shorter than you think. Half a page to three quarters of a page, rarely more, which usually means three or four tight paragraphs. Recruiters read dozens of applications in a single sitting, and a wall of text gets skimmed at best. If you cannot make your case in roughly 250 to 350 words, the problem is normally focus rather than a lack of space. Cut the throat-clearing and lead with your strongest example.
How to end a cover letter
Close with intent, not with a whimper. A line that says what you would like to happen next, whether that is an interview or a short call, works better than "I look forward to hearing from you," which nearly every other applicant also writes. Thank the reader briefly, sign off with "Yours sincerely" if you used their name and "Yours faithfully" if you did not, and then stop. Resist the urge to bolt on a postscript pleading for consideration.
What to leave out
A few habits quietly sink otherwise good letters. Salary demands belong in a later conversation, not the opening pitch. Complaints about a current employer read as a warning sign. Generic flattery about a "prestigious company" is transparent. And the same letter fired at twenty employers with only the company name swapped is easy to spot, because it never mentions anything specific. If a paragraph could sit inside any application at all, cut it.
For a wider sense of the form and where it came from, the Wikipedia entry on the cover letter is a useful reference, and communities such as r/jobs on Reddit are full of real examples, both good and bad, that are worth reading before you draft your own.
Tailor every letter, every time
The single biggest lift comes from matching the letter to the specific advert in front of you. Read the job description twice, underline the words the employer keeps repeating, and make sure those exact priorities appear in your examples. A tailored letter takes an extra fifteen minutes, but it reads as though you wrote it for that one role, because you did. That effort is obvious to a reader who sees generic applications all day, and it is often the difference between a polite rejection and a first interview.
Treat it as an argument
A cover letter is not a formality to survive. It is the one part of an application where you speak in your own voice and connect your experience to a specific need. Treat it as an argument rather than an introduction, keep it short, and make every line earn its place. Do that, and the letter stops being the thing you dread and becomes the reason you get the call.
