Do you even need one?
Check the job listing first. If it says "no cover letter" or "cover letter optional," a short, well-written one still rarely hurts — but a poor one can. If the listing says nothing, include one. If it explicitly asks for one, write a good one.
The default position: when in doubt, write it. A hiring manager who reads it and finds it useful is in a better position than one who wonders why you didn't send one.
What a cover letter is actually for
A cover letter isn't a re-reading of your CV. It's the one place you can speak directly to the hiring manager as a person, not as a list of bullet points.
It should do three things:
- Say specifically why you want *this* role at *this* company (not a copy-pasted generic line)
- Point to one or two things from your CV that are most relevant to their needs
- Be short enough to actually get read
Structure that works
Opening paragraph — get to the point
Don't open with "I am writing to express my interest in…" That's the most common opening line in any recruiter's inbox. It says nothing.
Instead, open with the *specific* reason you're applying:
*"I've been following [Company]'s work in carbon accounting since your research team published the 2024 footprint report — and the Head of Analytics role caught my attention immediately because your current data gaps map precisely to the analytical work I've been doing for the last three years."*
One sentence or two. Specific, direct, and already different from 90% of what they'll read.
Middle paragraph(s) — make the connection
Pick one or two things from your CV that speak most directly to the role. Expand on them — not to repeat information, but to add context that the CV can't carry.
What can't fit in a CV bullet point:
- Why you made a decision
- What you learned from a project
- How a skill developed over time
- What drew you to this kind of work
Keep it to 2–3 short paragraphs at most. Don't narrate your entire history. If it's taking longer to write than to read, it's too long.
Closing — be clear about what comes next
Don't end with "I look forward to hearing from you" on its own — it's passive. Be slightly more direct:
*"I'd welcome the chance to talk through how my experience mapping geospatial data at scale fits what you're building. I'm available for a call this week or next."*
One confident sentence is enough. Then sign off.
What to avoid
- Flattery: "You are the world leader in…" reads as padding
- Restating the CV: "As you can see from my attached CV, I have five years of experience in…" — they'll read the CV
- Weak hedging: "I believe I may be a good fit…" — either you are or you're not
- Template phrases: "I am a passionate team player with a proven track record of…" — every cover letter says this
- Length: If it's over half a page, it's too long for most roles
The right length
Aim for 250–350 words. That's three to four short paragraphs. A hiring manager reading dozens of applications will notice a cover letter that respects their time.
