Most cover letter rejections trace back to a small set of avoidable mistakes.

You'd be shocked how often a strong candidate loses an interview because their cover letter opened with 'To Whom It May Concern' and closed with 'I hope to hear from you soon.' Recruiters read the first two lines and decide whether to keep going.

These are the ten mistakes we correct most often in cover letter audits — and the fixes to apply before you send another application.

The 10 Mistakes

  • 1. Generic opening ('To Whom It May Concern' — always looks lazy).
  • 2. Restating the resume verbatim instead of adding context.
  • 3. No mention of the company, product, or mission.
  • 4. Full page of text — reads as noise, cut to 3/4 page.
  • 5. Keyword stuffing to match the JD word-for-word.
  • 6. Different font or formatting than the resume.
  • 7. Contact info in a graphic header the ATS can't parse.
  • 8. No measurable achievement in the proof paragraph.
  • 9. Weak close ('Thank you for your consideration').
  • 10. Attaching as an image or scanned PDF.

The Quick Fixes

  • Replace 'To Whom It May Concern' with 'Dear [Team Name] Team'.
  • Add one measurable result the resume didn't have room for.
  • Reference something the company shipped or announced in the last 6 months.
  • Match your resume's font, size, and header block.
  • End with a specific ask: 'I'd love the chance to discuss how my [skill] could support your [goal].'

The One-Minute Test Before Sending

  • Read the first sentence — would you keep reading if you were the recruiter?
  • Search the letter for the company name — appears at least once?
  • Count keywords — 5–7 from the JD, no more.
  • Copy-paste into Notepad — does the format survive?
  • Read the close — does it request a specific next step?

Key Takeaways

  • Generic openings and closes signal low effort — cut them.
  • Add context the resume can't fit; don't restate the resume.
  • Match the resume's formatting so both parse consistently.
  • One measurable achievement in the proof paragraph does most of the work.

Frequently Asked Questions

Is 'To Whom It May Concern' really that bad?

Yes. It's the most-cited cliché in recruiter surveys. 'Dear [Team] Team' or 'Dear Hiring Manager' both outperform it.

Should I always reference the company?

At least once, and preferably something specific from the last 6–12 months. It's the highest-signal move in a short letter.

Conclusion

Cover letters aren't dead — lazy cover letters are. Fix these ten mistakes and the letter starts working for you instead of against you.
