Why cover letters get rejected: the six things a reviewer actually scores

Most cover letters do not get rejected for a mistake. They get rejected for being interchangeable.

Here is the test a hiring manager runs without thinking about it. Swap the company name in your letter for a competitor’s. Does the letter still read fine? Then it was never about this job, and the person reading it can feel that in the first paragraph.

Our free cover letter review scores letters on six dimensions. This article is that rubric, written out, with a weak and a strong version of each so you can grade your own letter before anyone else does.

The scale a reviewer is using

Before the six dimensions, it helps to know what the numbers mean. The review uses the same 0 to 100 scale for every letter, anchored like this:

• 90 to 100. A specific opening that could only have been written for this role, concrete evidence in every paragraph, natural voice, tight and purposeful.
• 75 to 89. Clearly tailored with real examples. A few generic sentences or one soft paragraph.
• 60 to 74. Competent but interchangeable. The company name could be swapped out and the letter would still read fine.
• 40 to 59. Mostly filler. Restates the resume, leans on stock phrases, little evidence.
• Below 40. Would actively hurt you. Wrong role or company, no evidence, or a serious tone problem.

Most letters we see land in the 60s. That is not a failing grade in school terms, and it is exactly the band that gets nothing back. The whole game is getting out of “interchangeable” and into “clearly tailored.”

1. Opening hook: does the first sentence earn the second?

A hiring manager reads the first sentence to decide whether to read the second. That is the entire job of the opening.

The most common opener in the pile announces the application. It names the job board. It says nothing the reader did not already know from the subject line.

Weak:

I am writing to apply for the Operations Coordinator position I saw on LinkedIn. With my background in logistics and my passion for efficiency, I believe I would be a great fit for your team.

Strong:

Last spring I rebuilt the shift-scheduling process for a 40-person warehouse team, which is why the Operations Coordinator role caught my eye.

The strong version is shorter, says something only this candidate could say, and connects it to the role in the same breath. Notice what it does not do. It does not say “I am writing.” It does not mention where the posting was found. It does not use the word “passion.”

The rule the reviewer applies: penalize any opener that starts with “I am writing to apply for” or names the job board. Both are automatic points off, because both signal that the first sentence was written on autopilot.

2. Specificity: evidence, or adjectives about yourself?

This is the dimension that separates the 60s from the 80s. Adjectives are free. Anyone can write “detail-oriented.” Evidence costs something, because you had to actually do it.

Weak:

I am a results-driven professional with strong communication skills and a proven track record of success in fast-paced environments.

Strong:

I ran the weekly forecast meeting for three regional managers, cut the report they read from nine pages to two, and the meeting went from an hour to twenty minutes.

Count the nouns you could verify in each version. The weak one has none. The strong one has a meeting, a headcount, a page count, and a duration. A reader does not have to believe you are results-driven. They can see it.

If you do not have a number, use scope, frequency, tools, or a named decision instead. “I chose to move the team from email to a shared queue” is specific even without a metric. “I improved communication” is not.

3. Job alignment: connected to this role, or asserted?

Alignment is where the swap test bites. A letter can be full of real evidence and still fail here, because the evidence was chosen for the candidate rather than for the job.

Weak:

My experience makes me an ideal candidate for this role, and I am confident I can contribute to your team’s goals from day one.

Strong:

The posting asks for someone who can own vendor onboarding end to end. At Halvorsen I onboarded 14 suppliers in a quarter, wrote the checklist the team still uses, and cut the average onboarding time from three weeks to eight days.

The weak version asserts fit. The strong version names a requirement from the posting and puts a matching result next to it. The reader does not have to do the mapping; you did it for them.

Practically, this means reading the posting before you write, picking the two or three requirements that matter most, and making sure each has a paragraph or a sentence that answers it with something you did. The free review scores this dimension against the job description when you paste it in. Without a posting, it can only judge whether the letter is tailored to any role at all.

4. Tone and authenticity: does it sound like a person?

Three things fail this dimension: corporate boilerplate, reaching for the thesaurus, and the flat cadence of unedited AI output.

Weak:

Moreover, I am deeply committed to leveraging my expertise to drive impactful outcomes. Furthermore, I thrive in collaborative environments and am passionate about fostering innovation.

Strong:

I like the unglamorous parts of this work. The onboarding checklist was not exciting to write, but it is the reason nobody on the team has to ask me how vendor setup works anymore.

The weak version could have been generated for any job on earth. Every sentence is the same length. “Moreover” and “furthermore” are doing the work that actual content should do. The strong version has an opinion, a concrete object, and a sentence rhythm that changes.

The tell for AI-sounding text is not that it is wrong. It is that it is smooth. If your letter praises the company in a way that reads like its About page, or arrives in tidy groups of three, edit until at least one sentence contains something only you would have said.

5. Structure and length: 250 to 400 words, and every paragraph moves

A cover letter should be roughly 250 to 400 words. Under that, it usually says nothing. Over it, the reader skims, and skimming is where your evidence gets lost.

Weak: a single 480-word block that opens with your career history from 2015, moves to your values, mentions the role in paragraph four, and closes with your availability.

Strong: three or four paragraphs. The opening is one specific hook. The middle is one or two paragraphs of evidence, each tied to a requirement in the posting. The closing is two or three sentences with a next step.

The review counts the words in the body itself, excluding the address block, date, and signature, and flags padding in both directions. A short letter that says nothing scores as low as a long one that buries the point.

6. Closing: a concrete next step, or a trail-off?

The last sentence is the second thing a reader remembers. Most letters throw it away.

Weak:

Thank you for your time and consideration. I look forward to hearing from you and hope to have the opportunity to discuss my qualifications further.

Strong:

I would like to walk you through the onboarding checklist and where I think it would break at your scale. I am free any afternoon next week.

The strong version proposes something specific, shows a little confidence without begging, and makes the next step easy. The weak version is the closing everyone writes, which means it signals nothing.

The red flags a reviewer notices before the scores

Separate from the six scores, the review lists red flags. These are the things a hiring manager sees in the first ten seconds, before they have consciously evaluated anything. Any one of them can end the read.

• Cliches. “I am writing to express my keen interest.” “Team player.” “Wear many hats.” Stock phrases the reader has seen a thousand times.
• Generic filler. Sentences that assert enthusiasm or fit without evidence and would survive a find-and-replace of the company name.
• AI-sounding text. Uniform sentence length, “moreover” and “furthermore,” tidy tricolons, company praise that reads like marketing copy.
• Tone mismatch. Over-familiar, servile, or grandiose relative to a professional application.
• Formatting. A broken salutation, an unaddressed “To Whom It May Concern,” a wrong or missing company or role name. This one is fatal more often than you would expect, because it is proof the letter was recycled.
• Unsupported claims. A claim in the letter that the attached resume does not back up. The review only checks for this when you supply your resume alongside the letter, which is one good reason to.

An empty red-flag list is a real result, not a consolation prize. A well-written letter should have none.

What to do in the next ten minutes

You do not need to rewrite the whole letter. The parts worth keeping are the ones only you could have written, and a good review protects those. Do this instead:

1. Delete the first sentence. Replace it with the single most relevant thing you have done for this kind of role.
2. Find every adjective about yourself. Replace each with a noun you could verify: a project, a number, a decision, a tool.
3. Open the posting. Pick the two requirements that matter most. Make sure each one has a sentence in your letter that answers it with evidence.
4. Read the letter out loud. Any sentence that you would never say to a person, rewrite or cut.
5. Rewrite the last sentence to propose a specific next step.
6. Run the swap test. Change the company name. If the letter still reads fine, go back to step 3.

Then run it through the free cover letter review. It scores the six dimensions, lists the lines that are weak with a drop-in rewrite for each, and only reuses facts already in your letter. Where a stronger version needs a number you did not give it, you get a placeholder to fill in rather than an invented figure. If you upload a file, it comes back byte for byte.

If your resume is the weaker half of the application, start with the free resume review instead. A letter can only align to a resume that already makes the case.
