  • 2Use decision rules: write a cover letter for requested applications, career changes, senior roles, or when you have unique value to explain.
  • 3Keep cover letters short (150–200 words), lead with a quantifiable hook, and end with a clear call-to-action.
  • 4Tailor at scale by maintaining templates, a company research sheet, and using tools like Resumize.ai to generate customized drafts quickly.
  • 5For pivots or complex histories, map three transferable skills and provide concrete evidence (projects, certificates, metrics).

Conclusion

Frequently Asked Questions

Attach a cover letter only if the system accepts attachments and the role benefits from additional context (senior, client-facing, or career-change roles). If the ATS restricts attachments, use the application’s summary field or LinkedIn message to include a concise 2–3 sentence pitch.
Aim for 150–200 words (roughly one short paragraph plus two supporting paragraphs). Hiring managers skim quickly, so focus on a strong hook, one quantified achievement, and a brief fit statement with a clear call-to-action.
Yes, AI tools like Resumize.ai can produce high-quality drafts that save time. However, always personalize the AI output with one company-specific sentence and proofread for accuracy and tone. AI should speed the process, not replace your judgment.
Absolutely. A concise cover letter allows you to address employment gaps positively by focusing on transferable skills, continuing education, or portfolio work that shows readiness for the role. Keep explanations brief and outcome-focused.
