The conventional wisdom says always include a cover letter unless the application specifically says not to. The practical reality is more nuanced. Some roles genuinely value a well-written cover letter. Others go directly to the resume. Understanding which situation you are in helps you invest your writing effort where it will have the most impact.
Roles where cover letters genuinely matter
Cover letters matter most in roles where writing is itself a core competency, communications, marketing, public relations, consulting, policy, and similar fields. In these roles, a cover letter is a work sample. Recruiters read it to assess how well you write, how clearly you think, and whether your voice fits the company.
Cover letters also matter more at smaller companies where hiring is less process-driven. At a startup with a ten-person team, the hiring manager is likely reading every application personally and a compelling letter that shows genuine interest in the company and role can make a real difference.
For roles that are highly competitive and where your application needs differentiation, a strong cover letter can provide the context your resume cannot. If your career path is non-linear, if you are changing industries, or if there is something about your background that needs explaining, a cover letter is the right place to do it.
Roles where cover letters rarely get read
At large companies with high application volumes, especially in technical roles, cover letters often go unread in the initial screening phase. Recruiters reviewing 200 applications for a software engineering role are focused on the resume. The cover letter is opened, if at all, only after the resume has already passed the initial screen.
For roles where speed of screening is paramount, writing a cover letter is often a poor investment of your time relative to spending that same time optimizing your resume or researching the company for an interview. Know your audience.
Easy Apply applications on LinkedIn often do not include a cover letter option at all. When the application method does not support one, you obviously do not need one. When it does support one but does not require it, use the context to judge whether this is a role where it will be read.
How to write a cover letter that actually gets read
The cover letters that get read are short, specific, and direct. Three to four short paragraphs. The first sentence tells the recruiter exactly why you are excited about this specific role at this specific company. Not a generic opener, a specific one.
The middle section connects your most relevant experience directly to what the role needs. Not a summary of your resume, but a focused argument for why your background is specifically relevant to their situation. One or two concrete examples that are not already obvious from your resume.
The closing is confident and direct. Something like: “I would welcome the chance to discuss how my experience building customer success teams in high-growth SaaS companies could support your team’s goals.” Then stop. Long closings with multiple hedged phrases like “I look forward to hearing from you at your earliest convenience” add nothing.
The difference between a generic and a specific cover letter
A generic cover letter says: “I am excited to apply for the Marketing Manager position at [Company]. I am a results-driven professional with experience in marketing and communications, and I believe my skills would be a strong fit for your team.”
A specific cover letter says: “I saw that your team is expanding into the mid-market segment, and I spent the last three years building the marketing infrastructure that helped my company’s expansion from SMB to mid-market grow ARR from $8M to $45M. I would like to talk about how those same approaches might support what you are building.”
The specific version requires more effort. It requires you to actually research the company, understand their current situation, and connect your experience to it. That effort is exactly what makes it worth reading. Generic cover letters are not worth the time they take to write or to read.
Cover letter length: what actually works
One page maximum. Most effective cover letters are three to four paragraphs, totaling two hundred to three hundred words. If you find yourself writing more than that, you are probably repeating your resume or explaining things that do not need explaining.
Each paragraph should have a clear purpose: introduction and hook, relevant experience connected to the role, evidence of company-specific research or fit, and a direct close. If a paragraph does not serve one of those purposes, cut it.
Do not pad a cover letter with pleasantries, background that is already in your resume, or phrases that could be copied and pasted into any application. Every sentence should either tell the recruiter something specific about why you are a strong fit for this role or give them a concrete reason to read your resume with more attention.

Frequently Asked Questions
Should I always include a cover letter?
Include one when requested, when writing ability is core to the role, or when you need to explain context your resume cannot. For high-volume technical roles, it is often not read.
How long should a cover letter be?
Three to four short paragraphs, 200-300 words maximum. If you are writing more, you are probably repeating your resume.
What should the first sentence of a cover letter say?
Start with something specific. “I have spent four years doing exactly what this role requires” beats “I am excited to apply for this position.”
What should I leave out of a cover letter?
Do not restate your resume, explain why you need the job, apologize for gaps, or use clichés. Every sentence should add information not already in the resume.

Anonymous and approximate. We store one number for this article and nothing about you.
Email digest
We also run a layoff tracker, built from company filings and official notices. A plain email summary of what changed on these trackers: headline numbers, the largest new entries, and links to the sources. You confirm your address by clicking a link we email you, and one click unsubscribes. Already subscribed? Use this form to change what you get. The boxes replace what you had.
Our mail provider records whether you open an email and which links you follow, including the confirmation email, which is measured before you have agreed to anything. Unsubscribing stops the sending and the recording together.
You can read every past edition first. Each one is kept permanently, exactly as it was sent.
Privacy note: what we store and how to erase it
What we store: your email address, the choices above, and timestamps (signed up, confirmed, last sent). Nothing else about you.
What our mail provider records: whether you opened an email and which links you followed, tied to your address. That is Brevo, the service that delivers these emails, and it works by adding a small invisible image and by routing links through its own address. We read it to see which sections people use. Unsubscribing stops the sending and the measuring at the same time, and erasing your row removes it from our side.
The confirmation email is measured too: the same invisible image is in the one message that asks your permission. If you open it, Brevo records that against your address before you have agreed to anything, and it records it even if you then never confirm. We would exempt that message if we could. Brevo offers no way to switch its measuring off for a single email, and the one setting that exists covers every email we send or none of them. If you would rather not be measured at all, do not open it. Nothing else is ever sent to an unconfirmed address, and the signup is deleted from our side after 30 days.
About the links: links in the digest pass through a counter on this site that adds 1 to a total for that link and sends you straight on. It records no identifier, no IP address and no browser details, so it counts how many times a link was followed and can never say who followed it.
What it is used for: sending you exactly the emails you ticked, nothing else. The address is never shared, sold, or used for any other purpose.
How to erase it: click the unsubscribe link in any email. That stops all sending immediately, and unsubscribed addresses, along with signups that were never confirmed, are hard-deleted automatically after 30 days. You can also ask via the contact page.
