The Cover Letter Is Dying

The cover letter is dying slowly, and the data is finally catching up to what hiring managers have been saying privately for years.

A 2026 ResumeGenius survey of 625 hiring managers found that 65% do not read cover letters for every application.^[1] Greenhouse's 2025 research across the US, UK, Ireland, and Germany describes the wider problem: employers and candidates are both using AI while trust in hiring is falling.^[2]

The cause is not mysterious. Wharton's Knowledge faculty have argued straightforwardly that "AI Is Killing the Cover Letter" — mass LLM adoption has stripped the format of its signaling value, because generation is now effectively free.^[3] iHire's 2025 State of Online Recruiting survey found that 29.3% of job seekers had used AI to write or customize a resume or cover letter, up from 17.3% in 2024.^[4]

Polished became the new baseline. Baselines aren't signals.

What Hiring Managers Actually Reward

If polish is no longer signal, what is?

The ResumeGenius research has the clearest answer I've seen. 78% of hiring professionals said generic and tailored letters were easy to distinguish, and 81% valued tailored letters more.^[1] Specificity is the variable hiring managers say they're actually weighting.

That maps to what I've seen working in 2025-2026:

1. A specific reason this role. Not "I'm passionate about your mission." A two-sentence explanation of why this team, this stack, this customer base, this stage of the company.
2. A concrete connection between your background and what they need. One project, one outcome, one number.
3. Evidence outside the form. A portfolio link, a write-up, a recording — anything that's harder to fake than a paragraph.

The Formats That Are Getting Used

A few alternative formats are growing fast enough to mention by name.

Async intro videos

Tools like Loom, Willo, and Spark Hire have made it trivial to attach a 60-second video to an application. Async video platforms report candidate completion rates around 80% on structured interview invites,^[5] which is the wrong comparison to a cover letter but the right reference for "candidates will do this when asked."

The honest caveat: I haven't seen a clean head-to-head study showing intro videos beat cover letters on response rate. What I can say is that intro videos are rare enough in cold applications that submitting one is itself a signal: this person took this seriously enough to record themselves. The bar is "did this person take this seriously?" That bar filters out essentially all bot traffic.

Personalized direct outreach

This is the lever with the cleanest supporting data. Salesso's 2025 LinkedIn InMail analysis puts personalized outreach at ~9.4% reply rate vs. ~5.4% for generic messages, with top personalized performers reaching 18–25%.^[6] That's recruiter-to-candidate data, not candidate-to-hiring-manager, but the directional point — personalization roughly doubles reply rate — has held across studies for years.

For a job application, the play is: find the hiring manager, reference something they've published or worked on, and send a short message. The evidence supports a directional advantage for personalization, not a guaranteed response rate. The catch is that it does not scale. You can do five of these a week. That's the point.

A short, specific cover letter when one is required

Three sentences, not three paragraphs:

1. The specific thing about this role/team that made you apply
2. The one most relevant thing on your resume
3. One concrete question or proposal that shows you've thought about the actual work

This is faster to write, easier for the hiring manager to read, and harder to generate generically.

What About AI-Detection at Intake?

I expected to find that major ATS platforms now auto-flag AI-generated cover letters. They mostly don't. Jobscan's 2026 review explicitly states that Workday, Greenhouse, and Lever do not auto-detect or auto-reject AI-written applications.^[7]

That doesn't mean nobody notices. The same hiring-manager research says tailored and generic letters are easy to distinguish.^[1] The point isn't that bots get filtered automatically. It's that bot-grade output gets deprioritized by humans who've now seen ten thousand examples of it.

In Practice

Almost nobody is doing this. The applicants getting hired in 2026 figured out that "more applications" stopped working and "more distinctive applications" started working.

A Note on Camera Anxiety

A lot of people stop reading at "record yourself on camera." Fair. It's uncomfortable.

The video doesn't need to be polished. It needs to be a person. Bad lighting is fine. Stumbling on a sentence is fine. Reading from notes is fine. What it needs to convey is that there's a specific human attached to this application who has thought about this specific role for more than nine seconds.

Record it once. Reuse it for similar roles. Re-record only when the role or company is meaningfully different. Most applicants drastically overestimate how many videos they need to make.

Stay Organized

Track which roles got the video, which got the personalized outreach, which got the bare-minimum cover letter, and what your response rates look like across the three. You'll be surprised. Oplinque is free for this; a spreadsheet works too.
