A cover letter can make or break your job application. While many candidates focus on what to include, far fewer understand what to avoid—and that’s often where mistakes happen. Even a well-qualified applicant can be rejected due to poor tone, generic content, or simple formatting errors.
Recruiters typically spend less than 10 seconds scanning a cover letter. That means every word matters. A single mistake—like using a generic greeting or repeating your resume—can reduce your chances dramatically. Understanding common pitfalls is essential if you want your application to stand out in a competitive job market.
In this comprehensive guide, you’ll learn the most critical mistakes to avoid in a cover letter, supported by examples, checklists, and expert insights. Whether you’re writing your first application or refining your job search strategy, this article will help you create a professional, effective, and compelling cover letter.

One of the biggest issues candidates face is making avoidable mistakes that immediately signal a lack of professionalism. These errors can range from small typos to major structural flaws.

| Repeating resume | Adds no value | Highlight key achievements |
