Cover Letter Mistakes That Get You Rejected

A cover letter has one job: make the hiring manager want to read your resume. Most letters fail before the second paragraph, not because the candidate is unqualified, but because the letter repeats the resume, sounds generic or makes the reader work too hard. Here are the most common mistakes and how to fix each one.

1. Starting with "I am writing to apply for..."

Recruiters read this sentence dozens of times a day. It tells them nothing. Open with the most relevant thing about you instead.

Weak: "I am writing to apply for the Marketing Coordinator position at Brightside."

Better: "Last year I grew an email list from 2,000 to 11,000 subscribers for a local retailer, and I would like to bring the same approach to Brightside as your Marketing Coordinator."

2. Repeating your resume line by line

The resume lists what you did. The cover letter explains why it matters for this job. Pick two or three experiences that match the job posting and tell the short story behind them: the problem, what you did and the result.

3. Sending the same letter to every company

Hiring managers can tell when a letter was copied. Mention something specific: a product you use, a recent project, a value on their careers page. One genuine sentence about the company is worth more than a paragraph of general praise.

4. Talking only about what you want

"I am looking for a role where I can grow" is honest but self-focused. Employers hire to solve problems. Frame your skills around what the team needs, then mention growth briefly at the end.

5. Making it too long

Keep it to one page, roughly 250 to 350 words, in three or four short paragraphs. If you cannot say it in one page, the message is not clear yet.

6. Typos and wrong names

Using the wrong company name or misspelling the manager's name can end your application on the spot. Read the letter out loud, then check names, job title and dates one more time. If the posting does not name a person, "Dear Hiring Team" is fine.

7. Apologizing or underselling

Phrases like "although I do not have much experience" or "I know I am not a perfect fit" hand the reader a reason to say no. If there is a gap, focus on related skills and your ability to learn quickly, with an example.

8. Using empty buzzwords

"Results-driven team player with excellent communication skills" could describe anyone. Replace adjectives with evidence: "I coordinated a team of six volunteers to run a food drive that collected 1,800 pounds of donations."

9. No clear ending

Close with confidence and a next step: "I would welcome the chance to discuss how I can support your content team. I am available for a call any weekday afternoon." Then thank the reader.

10. Ignoring the job posting

The posting tells you what the employer cares about. If it mentions "managing vendor relationships" three times and your letter never touches on vendors, you have missed the point. Highlight the three requirements that appear most often, then make sure your letter gives one real example for at least two of them. Use the same terms the posting uses where they honestly describe your work, because some companies screen applications with software that looks for matching language.

11. Hiding the useful number

Numbers make claims believable, but only when they are true and easy to verify. Compare these two sentences.

Vague: "I improved the front desk process and helped customers."

Specific: "I redesigned the check-in process at a 12-room clinic, which cut average waiting time from about 20 minutes to about 12 and meant fewer patients left without being seen."

If you do not have exact figures, an honest estimate with the word "about" is fine. Never invent a number you cannot explain in an interview.

A short example letter

Here is a compact letter of about 200 words for a customer support role. Use it as a pattern, not a script.

Dear Hiring Team,

Last spring I answered about 60 customer emails a day for an online bookstore and brought our average reply time from two days to under six hours. I would like to bring that same focus on fast, friendly answers to the Customer Support Specialist role at Harbor Home Goods.

The posting asks for someone who can handle returns and explain policies clearly. At the bookstore, I rewrote our returns macros so customers saw the steps in a simple list, and the number of follow-up questions on returns dropped noticeably. I also trained two new teammates on our ticket system in their first week.

I shop at Harbor Home Goods and appreciate how clearly your product pages describe sizes and materials. I would enjoy helping customers feel as confident as those pages make them.

Thank you for your time. I am available for a call any weekday after noon.

Sincerely,

Dana Whitfield

Notice what it does: the opening gives proof right away, the second paragraph answers a specific request from the posting, and the third shows genuine interest without gushing.

How to edit your own draft in five passes

1. Cut the first sentence. Often the real opening starts in sentence two.
2. Circle every "I". If most sentences start that way, rewrite a few so they start with the employer's needs or a result.
3. Replace each adjective with proof. Delete "hardworking" and show the work.
4. Trim to one page. Remove anything the resume already says clearly.
5. Read it aloud. Awkward phrases and missing words are easy to hear.

A simple structure that works

1. Hook (2 sentences): your strongest relevant achievement and the role you want.
2. Proof (1 paragraph): two examples that match the job requirements.
3. Fit (1 paragraph): why this company and this team.
4. Close (2 sentences): thanks and next step.

Quick takeaways

• Open with your most relevant achievement, not a formal announcement.
• Tell the story behind two or three resume items instead of repeating them.
• Customize every letter with at least one specific detail about the company.
• Keep it to one page, roughly 250 to 350 words.
• Use true, specific numbers and proofread names, titles and dates.

Frequently asked questions

Do I always need a cover letter?

If the posting asks for one, yes. If it is listed as optional, a good letter can still help, especially when you are changing careers or your resume does not tell the whole story. A weak, generic one will not.

Should I write one for an internal job or an email application?

Yes, but keep it shorter. For an email application, a few sentences in the body of the email can serve as the letter, with the resume attached.

What if I do not know the hiring manager's name?

Try the company's website or professional networking pages. If you cannot find a name, "Dear Hiring Team" or "Dear [Department] Team" is perfectly acceptable. Avoid old-fashioned phrases like "To whom it may concern".

Can I use an AI tool to write it?

You can use one to get a draft or fix awkward wording, but the final letter must reflect your real experience. Add your own examples, delete anything inaccurate and make sure it sounds like you, because you may be asked about any line in an interview.
