Cover Letter vs No Cover Letter: When It Actually Matters

The cover letter debate has been raging for years. "Always send one." "Nobody reads them." "They're dead." "They can make or break your application."

The honest answer is: it depends. And understanding when it depends — and why — is more useful than a blanket rule in either direction.

When Cover Letters Are Actually Read

Cover letters get read in specific situations. Know them, and you'll know exactly when to invest time in one.

Direct applications to SMEs and startups

When you apply directly to a small or mid-size company — especially one not using an enterprise ATS — there's often a founder, department head, or office manager reading everything. They want to know you read the job description and you actually want this job, not just a job. A good cover letter here can be the difference between shortlist and rejection.

Roles that explicitly ask for one

If the job posting says "please include a cover letter" or "applications without a cover letter will not be considered," this isn't optional — it's a compliance check. Ignoring this instruction signals that you either didn't read the ad or you don't follow instructions. Neither is a good start.

Senior and leadership roles

The more senior the role, the more motivation, culture fit, and judgment matter. A cover letter for a Director or VP role gives a hiring manager context that a resume never can: why this company, why now, what you're bringing to a specific problem they have. At this level, skipping the cover letter is leaving a significant tool unused.

Career changes where your resume doesn't tell the story

If you're moving industries, switching functions, or returning after a gap, your resume alone will raise questions. A cover letter that directly addresses the transition — and explains why your background is actually an advantage for this role — does work that no amount of resume tweaking can replicate.

Referral applications

If someone referred you and the hiring manager is already expecting your name, a cover letter contextualises the recommendation and gives them something to work with when they mention you to the team. It also shows you took the referral seriously.

When Cover Letters Are Usually Ignored

Knowing when not to bother saves time and prevents you from submitting something generic that actually works against you.

High-volume applications through large job boards

When a company posts a role on a major job board and receives 400+ applications, the first pass is almost always ATS-automated. No human is opening cover letters at this stage. Your energy is better spent on ATS optimisation and a strong, keyword-aligned resume.

Roles using ATS-only screening with no human first pass

Some companies — particularly large enterprises and scale-ups with high hiring volumes — use ATS as their sole initial filter. If the system ranks you below the threshold, your cover letter never gets seen. Fix the resume before you worry about the letter.

Technical roles where skills and portfolio speak louder

For software engineering, data science, design, and similar roles, your GitHub, portfolio, or take-home project will matter far more than anything you write in a cover letter. Recruiters and hiring managers at tech companies know this. A brief, sharp summary is enough.

When "optional" means everyone sends one

Here's the nuance: when a role is highly competitive and the application form has an optional cover letter field, a large percentage of applicants will send one. If you skip it, you're at a disadvantage — not because yours would be read, but because yours is absent. In these cases, send one — but only if it's good.

The Risk of Not Sending One When It's Optional

When in doubt, send one.

A bad cover letter can genuinely hurt you: it signals low effort, poor writing, or that you copy-pasted something generic. Hiring managers notice.

A good cover letter never hurts. At worst, it's skimmed for 10 seconds and filed. At best, it's the thing that tips the decision in your favour when you're up against an equally-qualified candidate.

The question isn't whether to send — it's whether you can send a good one. If you can't, don't send a bad one. If you can, always send it.

What a Good Cover Letter Actually Does

A strong cover letter does specific work that your resume can't.

It answers questions your resume raises. Employment gap? Career change? Relocating from another city? Applying for a role slightly below your seniority level? A single sentence of direct explanation in a cover letter prevents a recruiter from drawing the wrong conclusion and moving on.

It shows you've read the job description. Mirroring the language of the posting — their exact terms for the role, the team, the problem — signals that you're applying specifically to them, not just farming applications. It's more noticeable than you'd think, because most applicants don't do it.

It adds one specific reason for this company, not just this role. A sentence about why this particular company — a product you use, a problem they're working on, a recent announcement that connects to your experience — is worth more than three paragraphs of self-description.

It stays under 300 words. Hiring managers at busy companies don't read essays. Three tight paragraphs: why this role, what you bring that directly matches, and a brief close. That's it.

What a Bad Cover Letter Looks Like

Bad: "I am writing to apply for the position of Marketing Manager as advertised on LinkedIn. I am a hardworking individual with excellent communication skills and a passion for marketing. I believe I would be an asset to your team and I look forward to hearing from you."

This cover letter tells the recruiter nothing. It mirrors no job description language, provides no specific claim, and could have been written by anyone for any role. It also starts with "I am writing to apply" — which is the most used opener in cover letters and the first thing that signals low effort.

Good: "Your job description mentions scaling organic acquisition in a competitive SaaS market — that's exactly what I spent the last 3 years doing at [Company], growing blog traffic from 12K to 180K monthly visits through SEO, content strategy, and conversion optimisation. I'd welcome the chance to bring that approach to [Company Name]."

This opener mirrors the job description language ("organic acquisition", "competitive SaaS market"), provides a specific metric, names the skill set, and signals genuine interest in this company specifically. It does more work in three sentences than most cover letters do in three paragraphs.

ATS and Cover Letters

Do ATS systems read cover letters? Some do, some don't — it depends on how the company configures their system. You can't know in advance.

Best practice: treat every cover letter as ATS-readable.

• No tables or columns — same rules as your resume
• Standard formatting — plain text structure, no design elements
• Keywords included — mirror the key terms from the job description naturally in your opening and body paragraphs
• Submit as DOCX or plain text PDF when given a choice

Even if the ATS ignores it, a human will eventually see it — and you want it to be clean and scannable when they do.
