| Section | Job it does |
|---|---|
| Opening | Earns the next sentence — no "I am writing to apply" |
| Proof paragraph 1 | One specific achievement, tied to the role's core need |
| Proof paragraph 2 | Why this company specifically, not just any company |
| Closing | Confident, direct, no apologizing for "taking your time" |
01Do you actually need one?
If the posting requests a cover letter, yes — skipping a requested one is one of the few instant, unambiguous ways to get filtered out before anyone reads your resume. If it's marked optional, a strong letter still adds context a keyword match can't: why you're making this move, what you understand about the role that a generic applicant wouldn't.
A weak cover letter costs you nothing you weren't already going to lose. A strong one is one of the only places left to actually stand out.
02Fix the opening first
"I am writing to apply for the [Role] position" tells the reader nothing they don't already know from the subject line. It's also the single most common opening line in every applicant pool, which means it's the fastest way to read as interchangeable with everyone else.
Generic opening
- "I am writing to apply for the Marketing Manager position."
- "I saw your job posting and I am very interested."
- "Please accept my application for..."
Opening that earns the next line
- Leads with a specific, relevant result
- Names the company or role's actual challenge
- Sounds like it was written for this posting, not copy-pasted
03Write two proof paragraphs, not a resume recap
A cover letter that lists the same bullets as the resume, just in sentence form, wastes the one advantage it has: room to explain why, not just what. Two paragraphs, each doing a different job:
04The mistake that ends applications instantly
Reusing the same letter for every application — and sometimes forgetting to update the company name from a previous one. It happens constantly, and it's an instant, unrecoverable signal that the application was mass-sent rather than considered. A tailored opening and one company-specific line take minutes; the alternative can cost the whole application.
Keep it short
3-4 short paragraphs, under 300 words. Long enough to make one real case, short enough that it actually gets read in full.
05Frequently asked questions
Do I still need a cover letter in 2026?
If the posting requests one, yes. If it's optional, a strong one still adds context an ATS keyword match can't.
How long should a cover letter be?
3-4 short paragraphs, under 300 words.
Should a cover letter repeat what's on my resume?
No. Pick one or two achievements and go deeper on the "why" instead of repeating the "what."
What's the biggest cover letter mistake?
Reusing the same letter for every application with just the company name swapped — and sometimes not even that.
