Most cover letters make the same mistakes. And most recruiters — who may read dozens of cover letters a day — can spot those mistakes in the first three sentences. If your cover letter is following any of these patterns, it could be undermining an otherwise strong application.
Mistake 1: Starting With "I Am Writing to Apply For..."
This is the single most common cover letter opener, and it wastes the most valuable real estate you have. The recruiter already knows you're applying — you're attached to a job application. Start with something that immediately communicates your value or creates interest.
Instead, try: "After five years driving 40% revenue growth at a B2B SaaS company, I'm excited to bring that same momentum to [Company Name]."
Mistake 2: Repeating Your Resume Word for Word
Your cover letter is not a prose version of your resume. Recruiters read both, and if your cover letter just restates your job titles and dates, you've wasted their time and a real opportunity. Use your cover letter to tell the story behind the resume — the context, motivation, and specific value you bring to this particular role.
Mistake 3: Making It All About You
Counterintuitively, the best cover letters aren't primarily about the candidate. They're about what the candidate can do for the company. Phrases like "I want to grow my skills" or "I'm looking for an opportunity to learn" focus on what you want. Shift the framing: what problem can you solve for them? What specific result can you deliver?
A strong cover letter answers one question from the employer's perspective: "Why should I spend time interviewing this person instead of the next candidate in my inbox?"
Mistake 4: Using a Generic Template With Zero Personalization
If you're sending the same cover letter to every company with only the company name swapped out, recruiters can tell. Research the company. Reference something specific — a recent product launch, a company value, a challenge in their industry. One specific, researched sentence is worth more than three paragraphs of generic enthusiasm.
Mistake 5: Writing More Than One Page
Recruiters are busy. A cover letter longer than one page signals poor communication skills and a lack of respect for the reader's time. Aim for three to four focused paragraphs. Every sentence should earn its place.
Mistake 6: Ending Passively
Ending with "I hope to hear from you" puts the ball entirely in the employer's court. It sounds uncertain and forgettable. End with a confident, specific call to action: "I'd welcome the opportunity to discuss how my background in supply chain optimization could support your Q3 goals — I'm available for a call any time this week."
Mistake 7: Not Proofreading
A typo in a cover letter — especially getting the company name wrong — is an immediate red flag about your attention to detail. Read it aloud, use spell-check, and have someone else review it before you hit send. Getting the company name wrong is an especially common and fatal error when using templates.
Before sending any cover letter, find one specific thing about the company — a recent news story, a product feature, a stated company value — and reference it in the opening or closing paragraph. This single change sets you apart from 90% of applicants.
What a Strong Cover Letter Actually Looks Like
A strong cover letter opens with impact, immediately explains why you're a strong fit for this specific role, shares one or two concrete achievements that demonstrate your value, shows genuine interest in the company (not just the job), and closes with a clear, confident call to action. It's specific, concise, and written for the reader — not for you.
