Few things in the modern job hunt inspire as much collective groaning as the cover letter. You've already submitted a résumé packed with your experience, skills, and accomplishments — and now you're being asked to write a formal letter essentially explaining the résumé you just submitted. It can feel redundant at best and performative at worst, especially when many applicants suspect nobody reads them anyway.
And yet, here they are — still a standard fixture on job application portals, still requested by employers large and small, still the subject of entire career-coaching industries. If cover letters were truly useless, market forces would have killed them off long ago. So what's actually going on? Why does this particular ritual persist?
The answer, like most things that survive longer than expected, is a mix of genuine original purpose, institutional inertia, and a few underappreciated functions that don't always get credit. Whether you love them, loathe them, or simply endure them, it's worth understanding why the cover letter exists in the first place.
What It Was Meant to Fix
The résumé, by design, is a structured document — a tidy grid of dates, titles, and bullet points. It is excellent at conveying what you did, but it is structurally limited in explaining why any of it matters to a specific employer. A résumé lists a career; it doesn't tell a story. The cover letter was invented to fill exactly that gap: to give applicants a space to connect their past experience to a particular role and explain their motivation for wanting it.
Employers, particularly in professional and managerial roles, have always needed to assess more than raw qualifications. Can this person communicate clearly in writing? Do they understand what our organization actually does? Are they applying thoughtfully or blasting out applications to a hundred companies at once? A well-crafted cover letter was meant to answer all three questions at once, serving as a quick and low-cost filter before the expensive process of interviews began.
There's also the matter of fit. Two candidates can have nearly identical résumés but wildly different reasons for applying — one is passionate about the mission, the other just needs a paycheck. The cover letter was designed to surface that distinction, giving hiring managers a signal about genuine interest and cultural alignment that a list of job titles simply cannot provide.
The Origins
The cover letter's roots stretch back to the era of formal business correspondence in the 19th century, when applying for a position meant sending a handwritten letter of introduction to a prospective employer — often with a separate document listing one's qualifications attached. The letter and the qualifications sheet were always a pair; one introduced the person, the other listed the credentials. This pairing was simply the professional norm of the time.
The modern résumé as a distinct document began taking clearer shape in the early 20th century, with career advisors and business schools in the United States formalizing its structure through the 1930s and 1940s. As the résumé became standardized, the accompanying letter of introduction became standardized alongside it, eventually earning the name "cover letter" — quite literally the letter that covered, or accompanied, the enclosed résumé. By the post-World War II economic boom of the late 1940s and 1950s, the cover letter was a firmly established convention in white-collar hiring.
The rise of typewriters, and later word processors in the 1980s, made producing polished cover letters accessible to more people, further cementing the practice. When online job applications emerged in the late 1990s and early 2000s — with platforms like Monster.com (launched in 1999) and later LinkedIn (founded 2003) — application forms simply digitized the existing convention rather than rethinking it, and the cover letter text box became a permanent fixture of the online hiring experience.
Why It Still Exists Today
One honest reason cover letters persist is institutional momentum. Hiring processes are deeply conservative by nature — companies develop workflows, train HR staff, and build applicant tracking systems around established conventions. Removing the cover letter field from an application requires a deliberate decision, and in the absence of that decision, it simply stays. Many hiring managers have never worked in a world without them and don't question their presence.
But there are also genuine functional reasons they survive. Studies and surveys of recruiters — including recurring data from the Society for Human Resource Management (SHRM) — consistently show that a meaningful portion of hiring managers do read cover letters, particularly for senior, creative, or client-facing roles where communication ability is a core job requirement. In those contexts, the cover letter isn't redundant; it is the test. A candidate who writes a compelling, well-targeted letter has already demonstrated a key skill the job demands.
Cover letters also serve an important function for the applicant. The act of writing one forces a candidate to articulate — to themselves, first — why they actually want a specific job. That process of reflection can sharpen interview performance, improve the quality of applications sent, and occasionally reveal that a candidate isn't as interested as they thought. In that sense, the cover letter is as much a tool for the applicant as it is a filter for the employer.
The Misunderstood Side
One of the most common misconceptions about cover letters is that they exist to summarize the résumé. This misunderstanding is so widespread that it has practically become the norm — and it's exactly why so many cover letters feel hollow. A cover letter that simply restates bullet points from a résumé adds no information and signals low effort. The format was never designed to be a prose version of your work history; it was designed to add context and voice that a résumé structurally cannot.
Another misconception is that cover letters are universally ignored. The reality is more nuanced: they are often skipped in high-volume, entry-level hiring, where recruiters process hundreds of applications and rely heavily on automated screening. But in smaller organizations, specialized industries, and senior-level searches, they carry considerably more weight. Declaring cover letters "dead" because they're skipped in some contexts is a bit like declaring conversation dead because people also send emails.
Finally, there's a tendency to view the cover letter as a hoop to jump through — an arbitrary obstacle invented by bureaucracy. In truth, it emerged from a very human need: the need to know who you're hiring, not just what they've done. Whether any individual cover letter achieves that goal depends enormously on how it's written and how carefully it's read. Like many workplace conventions, the cover letter is neither as useless as its critics claim nor as essential as its defenders insist — it is a tool, and tools are only as good as the hands that use them.
