Your cover letter is often your first impression — and for many candidates, it is also their last. Hiring managers typically spend 30-60 seconds scanning a cover letter before deciding whether to read your CV. One avoidable mistake can send your application straight to the rejection pile. Here are 7 cover letter mistakes that get people rejected in 2026, with real examples and exactly how to fix them.
For a comprehensive step-by-step approach to writing a winning cover letter, see our complete cover letter guide.
1. Opening with a generic introduction
The mistake: Starting with "I am writing to apply for the position of [role] at [company]." This opening tells the hiring manager nothing they do not already know (they are holding your application, after all). It wastes your most valuable real estate — the first sentence — on zero-value information.
Example of the mistake:
"Dear Hiring Manager, I am writing to apply for the Marketing Manager position at ABC Company. I believe I am a good fit for this role."
How to fix it: Open with a specific hook — an achievement, a connection to the company, or a compelling reason you are drawn to the role.
"When ABC Company launched its sustainability campaign last quarter, I knew I wanted to be part of a team that puts purpose at the centre of its marketing. As a Marketing Manager who grew organic traffic by 120% at my current role, I would love to bring that same energy to your team."
2. Making it too long
The mistake: Writing a full-page (or multi-page) essay that recounts your entire career history. Hiring managers are busy — they review dozens or hundreds of applications. A long cover letter signals that you cannot communicate concisely, which is itself a red flag for most roles.
How to fix it: Keep your cover letter to 250-400 words (roughly three-quarters of a page). Structure it in 3-4 tight paragraphs: a compelling opening, 1-2 middle paragraphs linking your experience to the role, and a confident closing with a call to action. Every sentence should earn its place. If a detail is already on your CV, do not repeat it — instead, add context or impact.
| Cover letter length | Hiring manager reaction | Recommendation |
|---|---|---|
| Under 150 words | Feels lazy, lacks substance | Too short — add more substance |
| 250-400 words | Concise, focused, respectful of time | Ideal length |
| 400-600 words | Acceptable if every line adds value | OK for senior roles |
| Over 600 words | Unlikely to be read in full | Too long — cut ruthlessly |
3. Focusing on yourself instead of the employer
The mistake: Writing "I want this job because..." and "I am passionate about..." without connecting it to what the employer actually needs. A cover letter that reads like a personal statement tells the hiring manager about your desires — but they are looking for someone who can solve their problems.
Example of the mistake:
"I am looking for a new challenge that will help me develop my skills in project management. This position would be a great step in my career."
How to fix it: Flip the perspective. For every "I want" statement, rewrite it as "Here is what I can deliver for you." Research the company's challenges, goals, and culture, then show how your experience directly addresses them.
"Your Q3 report highlighted a goal of reducing project delivery times by 20%. In my current role, I implemented an agile framework that cut delivery times by 25% across three teams — and I am excited to bring that methodology to your operations."

The mistake: Typos, grammatical errors, inconsistent formatting, or addressing the letter to the wrong company. A single spelling mistake can be enough to disqualify you — it signals carelessness, and hiring managers wonder: if this is the quality you deliver when trying to impress, what will you produce day-to-day?
How to fix it: Proofread at least three times — once for content, once for grammar, and once for formatting. Read the letter out loud; your ear catches errors your eyes skip. Use a spelling and grammar tool, but do not rely on it exclusively. Have a friend or colleague review it. Triple-check the company name, the hiring manager's name (if known), and the job title. Format consistently: one font, one font size, clear paragraph spacing.
5. Not tailoring to the specific role
The mistake: Sending the same cover letter to every employer with only the company name changed. Generic letters are obvious and signal that you are mass-applying rather than genuinely interested. Hiring managers see through "find-and-replace" applications instantly.
How to fix it: For each application, customise at least three elements: (1) why you are drawn to this company specifically, (2) which of your skills match this job description's key requirements, and (3) a reference to something specific about the company (a recent project, their values, their market position). Use keywords from the job posting to pass ATS filters. For tips on decoding what employers really want, see our guide to reading job postings.
6. Copy-pasting your CV into letter form
The mistake: Simply restating your CV in paragraph form: "In 2020 I worked at X. In 2022 I moved to Y. My responsibilities included..." This adds no new information and wastes the hiring manager's time. They already have your CV — the cover letter should complement it, not duplicate it.
How to fix it: Use the cover letter to tell the story behind your CV. Pick 2-3 achievements that are most relevant to the role and add context: what the challenge was, what you did, and what the measurable outcome was. Show personality, motivation, and how you connect to the company's mission. The cover letter is your chance to answer the question "Why you, why here, why now?"

7. No call to action in the closing
The mistake: Ending with a passive statement like "I hope to hear from you" or "Thank you for considering my application." These closings are forgettable and fail to convey confidence or initiative. They give the hiring manager no reason to prioritise your application.
Example of the mistake:
"Thank you for your time. I look forward to hearing from you."
How to fix it: End with a confident, specific call to action that expresses eagerness and availability.
"I would welcome the opportunity to discuss how my experience growing B2B pipelines can support your expansion goals. I am available for an interview at your convenience and can be reached at [phone/email]. Thank you for your time — I look forward to speaking with you."

Frequently asked questions
Do employers actually read cover letters in 2026?
Yes. The majority of hiring managers still read cover letters, especially for mid-to-senior roles. A strong cover letter differentiates candidates with similar CVs and demonstrates communication skills, cultural fit, and genuine interest in the role.
How long should a cover letter be?
The ideal length is 250-400 words (roughly three-quarters of a page). Hiring managers spend 30-60 seconds on an initial scan, so conciseness is key. Structure it in 3-4 short paragraphs with a compelling opening, relevant experience, and confident closing.
Is it okay to use the same cover letter for multiple applications?
No. Generic letters are the top reason for rejection. Customise at least the opening paragraph, the skills you highlight, and your company-specific research for each application. A template structure is fine, but the content must be adapted.
What should the first sentence of a cover letter say?
Lead with a specific achievement, a connection to the company, or a compelling value statement. Avoid "I am writing to apply for..." — it wastes your most valuable sentence. Make the reader want to continue.
Should I mention salary expectations in my cover letter?
Only if the job posting explicitly asks for them. In that case, provide a range based on market research. If not requested, leave salary for the interview stage where you have more leverage and context.
Conclusion
A cover letter is not a formality — it is your pitch. By avoiding these 7 mistakes, you transform your application from generic noise into a targeted, compelling case for why you are the right hire. Open strong, stay concise, focus on the employer, proofread relentlessly, and close with confidence. That is how you get interviews instead of rejection emails.
