The cover letter debate hasn't resolved — but the answer depends heavily on context. Here's a clear-eyed take on when they matter, when they don't, and how to write one that actually works.
The cover letter has been declared dead more times than most job search advice has been published. And yet recruiters at many companies still say a strong one makes a difference, and hiring managers at others say they don't read them at all. Both things are true, and knowing which situation you're in determines whether the effort is worth making.
The short answer: cover letters still matter in specific contexts, they've been diluted by AI-generated noise in others, and the right approach depends on where you're applying and what you want to communicate.
When They Still Matter
Cover letters carry the most weight at smaller companies, where the hiring manager is often also the reviewer, and in roles where writing is part of the job. If you're applying to be a marketer, copywriter, communications professional, or strategist, your cover letter is itself a sample of your work. A generic, formulaic one is a red flag. A sharp, specific one is evidence.
They also matter when you have something unusual to explain or communicate: a career pivot, a gap in your employment history, an unconventional background that's relevant in a non-obvious way. A cover letter is the right place to tell that story briefly and directly rather than hoping the resume makes the case on its own.
At the right company for the right role, a specific, well-written cover letter still opens doors. The people who say cover letters never matter are often generalizing from contexts where the volume is high and the screening is automated.
When They Don't
High-volume applications at large companies with automated screening often result in cover letters that are never read before the ATS filter runs. In these contexts, investing time in a cover letter produces less return than optimizing your resume for the role.
If the application is through a platform that doesn't include a cover letter field, or where the instructions explicitly say not to include one, don't. Ignoring instructions is worse than not writing one.
How to Write One That Works
Be specific and brief. One page maximum, preferably shorter. Open with something that demonstrates you've thought about this company and this role — not with 'I am writing to express my interest in.' Name something specific about the role or company and connect it to something in your background.
The middle section should answer the implicit question: why are you the right person for this specific role, given what you know about what they need? One or two concrete examples — not a recap of your entire resume — do this better than a summary paragraph. Close with one sentence about what you're hoping to do next in the conversation.
