Do Cover Letters Still Matter? When to Write One and When to Skip It

The honest answer is "it depends," which isn't satisfying but is more useful than the two extremes people usually argue — that cover letters are always essential, or that nobody reads them anymore. Both are true somewhere, just not everywhere at once. The deciding factor is less about industry and more about how the specific role is being hired for.

High-volume roles: usually skip, or keep it very short

Roles that receive hundreds of applications through a large careers site are frequently screened for keyword and requirement match before a human ever opens an attachment. A cover letter uploaded as a separate file in this pipeline often goes unread entirely. If the application form has an optional cover letter field, a three-sentence note that adds one piece of information not obvious from the resume is worth the two minutes it takes; a full page is not.

Smaller companies and specific referrals: usually worth it

At a company small enough that a hiring manager reads applications directly, or when you've been referred by someone on the team, a cover letter is far more likely to actually be read — and far more likely to matter, because it's one of the only places you get to explain motivation rather than just qualifications. A resume shows what you've done; a cover letter is the one place to say why this particular role, at this particular company, rather than any similar one.

What makes a cover letter worth reading

• It says something the resume can't — a reason for the career move, a specific connection to the company's product or mission, or context around a transition.
• It's short. Three to four paragraphs is a ceiling, not a target to fill.
• It names the actual company and role, not a placeholder left over from a template.
• It doesn't repeat the resume's bullet points in sentence form — that adds length without adding information.

The template trap

A generic cover letter that could be sent to any company in the industry is arguably worse than no cover letter at all, since it signals the letter was an afterthought rather than removing that impression. If you're applying broadly and can't write something specific for each posting, it's more honest — and usually more effective — to skip the letter and put that time into tailoring the resume instead.

A simple rule of thumb

If the posting explicitly asks for one, write it — skipping an explicit request is read as not following instructions, regardless of the company's size. Everywhere else, match the effort to how personally the application is likely to be reviewed: the smaller and more targeted the application, the more a genuine cover letter is likely to help.
