The real reason cover letters still get read
Most advice about cover letters focuses on what to write. The more useful question is why a busy reviewer bothers opening one at all.

A cover letter is, by most accounts, the least-read document in a job application, skimmed for a few seconds if it is opened at all. And yet recruiters consistently say a genuinely good one still changes an outcome. Those two facts are not actually in conflict.
What "skimmed" really means
A reviewer moving fast is not reading sentence by sentence, they are scanning for one thing: does this person clearly understand what the role actually needs, stated in their own words rather than restated from the job posting. That scan takes seconds, and most cover letters fail it in the first two lines by opening with a generic greeting and a summary of the attached resume.
What survives the scan
A single, specific line that shows real understanding of the role's actual problem, not the job title. "I have spent the last two years untangling a legacy billing system very similar to what your posting describes" reads completely differently from "I am excited to apply for this position," even though both are one sentence.
Why most advice makes this worse
Templates optimize for completeness, covering education, motivation, and fit in three tidy paragraphs, which produces a letter that is technically thorough and reads as generic precisely because every applicant's template looks the same. The specific line is the whole point; everything else in the letter is scaffolding around it.
The honest scope of what a cover letter can do
It rarely gets an underqualified candidate an interview, and it rarely loses a strongly qualified one their shot. Where it actually moves the needle is the wide middle ground, tie-breaking between similarly-strong resumes, which is exactly where most hiring decisions happen.
