The most common cover letter mistakes (and how to fix them)

No, the cover letter isn't dead

The idea that "nobody reads cover letters anymore" is largely outdated. According to several recent surveys of recruiting professionals, a large majority of recruiters say they read cover letters in full rather than skim them, and most consider them a real factor in deciding whether to invite a candidate to interview.

Some studies go further: a significant share of recruiters say a strong cover letter can get an otherwise average candidate an interview invite, while a weak one can sink an otherwise strong application. A majority of recruiters also report having rejected a candidate based on the cover letter's content alone, and a large share specifically cite spelling or grammar mistakes as a rejection reason.

Repeating the resume word for word

A cover letter isn't there to turn your resume into sentences. It should explain the why: why this role, why this company, why now. Recruiters expect new information, not a summary of what they already read on the resume. It's the place to give real context and genuine motivation, not to list dates and titles again.

A too-generic opening line

"I am writing to submit my application" tells the recruiter nothing. A good opening shows in one sentence that you understand the role and have a specific reason to apply, rather than a line that could be sent unchanged to any company.

Mistakes to fix first

• A letter that's too long: aim for 250-400 words, three to four paragraphs fitting on one page, essential over exhaustive
• No mention of the target company, an immediately recognizable sign of an unpersonalized mass send
• Content that simply duplicates the resume instead of going deeper on one or two specific examples
• A tone that's visibly AI-generated with no editing pass: recruiters say they can easily spot overly formal or repetitive phrasing, which reads as a lack of effort
• Stuffing in keywords lifted from the job posting, which makes the text feel artificial rather than relevant, on an exercise meant to demonstrate your ability to communicate clearly

A simple structure that works

A three-part flow covers most of what recruiters say they look for: an opening paragraph that hooks with genuine, specific motivation for the company, a middle paragraph directly connecting your experience to the role's concrete needs, and a closing paragraph that wraps up with enthusiasm and a clear opening toward an interview.
