Cover Letter — What to Include and What to Leave Out

I've Reviewed Hundreds of Cover Letters. Here's What Separates the Ones That Get Read From the Ones That Get Deleted

I want to tell you something as an HR professional who has sat on the hiring side of this process for over fourteen years.

Employer reading cover letter

When a cover letter comes through that is genuinely good — genuinely tailored, genuinely human, genuinely specific — it stands out so clearly that the hiring manager often forwards it to the team before they have even finished reading the resume.

And when a cover letter is generic, rambling, or missing the point entirely? It gets closed within fifteen seconds.

The gap between those two outcomes is not talent. It is not experience. It is knowing what to put in and what to leave out.


Why Most Cover Letters Fail Before the Second Paragraph

Here is the most common cover letter mistake I see — and it happens in the very first line.

"I am writing to apply for the position of Marketing Coordinator as advertised on your website."

That sentence tells the reader exactly nothing they don't already know. They know you're applying. They know where they posted the role. You have used your most valuable real estate — the opening line — to say absolutely nothing.

A cover letter has one job in the first ten seconds: make the reader want to keep reading. If your opening line doesn't do that, the rest of the letter rarely gets a chance to.

Now let's fix that — and everything else.


What to Put In Your Cover Letter

A Real Person's Name at the Top

"Dear Hiring Manager" is the cover letter equivalent of a mass text message. It tells the reader immediately that this letter was not written specifically for them.

Take five minutes to find out who you are actually writing to. Check the job posting, the company's LinkedIn page, or their website. If you genuinely cannot find a name after searching, "Dear [Department] Team" is warmer than the generic alternative. But the effort to find a real name is almost always worth it.

An Opening That Earns the Next Line

Your first sentence should either demonstrate genuine excitement about this specific company, reference something specific about their work, or lead with a career moment that is directly relevant to what they need.

Something like: "When I read your job description for this role, the phrase 'building systems that scale' immediately brought to mind the process redesign I led that cut onboarding time in half — and I knew this was a conversation worth having."

That sentence has a hook, a credential, and a reason to keep reading. That is what your opening line should be doing.

Two Accomplishments That Directly Answer "Why You?"

This is the heart of your cover letter. Not a paragraph about your personality. Not a list of adjectives. Two specific, concrete things you have done that prove you can do what they are asking.

Use numbers wherever you can. Not because recruiters are robots who respond only to data, but because numbers make vague claims real. "Improved customer satisfaction" is forgettable. "Brought customer satisfaction scores from 67% to 89% in one quarter" is a conversation starter.

Ask yourself before you write this section: if I had thirty seconds in an elevator with the hiring manager, what two things would I tell them I've done? Put those in the letter.

Genuine Reason You Want This Role Specifically

Hiring managers can tell the difference between a candidate who wants a job and a candidate who wants this job. The second type is dramatically more appealing to hire — because motivation and fit matter as much as skills.

Do your research. Read their About page. Look at what they've launched recently. Check what their leadership talks about publicly. Find something real that genuinely interests you and say so specifically. One focused, authentic sentence here outperforms a full paragraph of flattery.

A Closing That Moves Things Forward

Thank them briefly, restate your interest in one clear sentence, and indicate you look forward to the conversation. Keep it warm and direct. You do not need to be formal to the point of sounding robotic, but you do need to close with confidence — not with apology.


What to Cut From Your Cover Letter

Anything Already on Your Resume — Verbatim

Your cover letter and resume are a team. They should complement each other, not repeat each other. The resume lists what you did. The cover letter explains why it matters, what you learned, and how it applies to this role. If the reader could swap one for the other and not notice the difference, your cover letter isn't doing its job.

Meaningless Descriptors

"Hard-working." "Passionate." "Team player." "Results-driven." "Go-getter."

These words appear in almost every cover letter ever submitted. They are not wrong — but because everyone claims them, they mean nothing. Replace every adjective with a specific example. Don't tell them you're detail-oriented. Show them the moment your attention to detail caught something important.

Personal Details That Don't Serve the Application

Your commute situation, your family circumstances, your general life story — unless directly relevant to why you want this role or why you're a strong candidate, leave it out. A cover letter is not a personal essay. It is a professional pitch that happens to have a human voice.

Any Sentence That Starts With an Apology

"Although I don't have direct experience in..." / "Even though my background is primarily in..." / "I know I may not be the obvious choice..."

Every one of these opens a negotiation against yourself before the conversation has even started. If you are applying, apply with conviction. Address gaps by pivoting to transferable skills and genuine enthusiasm — not by spotlighting your own doubts.

Typos. Full stop.

A single typo in a cover letter can undo everything else you got right. Spell-check is not enough — read it aloud, read it backwards, and ask someone else to read it before you submit. A letter with errors signals to a hiring manager that either you don't care about this role, or you don't pay attention to detail. Neither is the impression you want to make.


The Real Purpose of a Cover Letter

A resume answers the question: What have you done?

A cover letter answers the question: Why are you the right person for this specific job at this specific company right now?

When you write your next one, keep that question front of mind for every sentence. If a line doesn't help answer it, cut it. If it does, make it as specific and human as you can.

A great cover letter will not get you the job on its own. But it can absolutely get you into the conversation — and that is all you need it to do.
