If you've searched this question before, you've probably found two completely different answers. Some sources will tell you cover letters are dead, a relic from before online applications and applicant tracking systems. Others insist they're still essential, and that skipping one costs you the job. Both of those can't be true at once, which is usually a sign the real answer is more conditional than either side wants to admit.
It is. Whether a cover letter helps you depends a lot on the role, the company, and honestly, on how good the cover letter actually is.
Reality Check
Cover letters aren't obsolete, but a generic one is worse than sending none at all.
A widely cited 2024 US survey of hiring managers found that only around a quarter read cover letters regularly, and nearly half never read them. That sounds like a case for skipping them entirely, until you notice what the same research and recruiters consistently say about the ones that do get read: specific, short, and clearly written letters still make a real difference. It's the vague, templated ones dragging the average down.
A resume tells an employer what you've done. It's not very good at explaining why you're applying, why now, or why this particular role, and that's exactly the gap a cover letter can fill. It matters most in a handful of situations: when you're changing industries or roles and your resume alone doesn't make the connection obvious, when you're applying to a smaller company where the hiring manager is likely reading applications personally rather than relying entirely on a screening system, and for senior or communication-heavy roles where how you write is itself part of what's being assessed.
Graduate programs, universities, and many NGOs still request one formally, and in those cases it's not optional, whatever the general trend looks like.
For high-volume roles, especially anything processed at scale through an applicant tracking system, the resume does most of the early work. Recruiters supporting dozens of open roles at once are often scanning for fast signals, like relevant experience, skills, and location, before a cover letter enters the picture at all. In that first pass, a strong resume that doesn't get shortlisted usually isn't rescued by a cover letter attached to it.
This doesn't mean cover letters are pointless for these roles. It means they tend to matter later in the process, once a shortlist is already forming and a recruiter is deciding between a few borderline candidates rather than filtering hundreds of applications.
The recurring advice across recruiters, again and again, comes down to the same thing: specificity beats length. A short, genuinely tailored paragraph that answers why you, why this role, and why now tends to outperform a longer, more generic letter that could have been sent to any employer in your field.
That also means restating your resume in sentence form isn't much of a cover letter at all. If a hiring manager can already see your work history on the page in front of them, repeating it back to them in paragraph form doesn't add anything. What actually adds value is context your resume can't provide on its own: the reasoning behind a career change, a genuine connection to the company's work, or a specific example that didn't fit naturally into your resume's bullet points.
Before deciding whether to write one, it's worth asking a few honest questions. Is this role at a smaller company, a senior position, or one where written communication is clearly part of the job? Does my resume already explain everything relevant, or is there real context missing, like a career change or an employment gap? If I do write one, can I say something specific to this role and this company, or would I just be restating my resume?
If the honest answer to that last question is "restating," it's genuinely better to either skip the cover letter or take the time to make it specific. A generic one isn't neutral. It actively signals less effort than no letter at all.
Writing a cover letter that's genuinely specific to a role starts with actually knowing where your experience aligns with what the employer is looking for, and where it doesn't. Guessing at that from a blank page is how most generic letters happen in the first place.
Vistr's cover letter generation works from your Job Match Analysis, pulling from the parts of your experience that genuinely align with the role, rather than producing a generic template filled in with your name and the job title. The goal isn't a faster way to write something forgettable. It's a faster way to write something specific.
