The mistakes

  • Repeating your resume word for word instead of adding context.
  • Using the wrong company name or a generic greeting when the name is easy to find.
  • Focusing on what you want rather than what you offer.
  • Writing more than one page.
  • Leaving out a clear call to action.
  • Apologizing for gaps or missing qualifications.
  • Skipping the proofread.

The fix

Tailor every letter, keep it to three or four focused paragraphs, and lead with the value you'll bring.
