10. Final Verdict: Should You Write One?

It depends. Studies show:

• ~53% of hiring managers say a cover letter influences their decision.
• But only ~26% read cover letters frequently.

✅ Bottom Line: A well-written cover letter won’t hurt—and could help. A bad one? Better not to send.

• You’re applying through a referral
• You’re making a career switch
• There are employment gaps to explain
• You’re applying for a role that involves writing, strategy, or communication
• The job posting requests one

In these cases, a cover letter helps you add context, tell your story, and build a stronger emotional connection.

• The application clearly says “no cover letter”
• There’s no option to upload or include one
• You can’t tailor it—sending a generic one is worse than none
• You're submitting via a mobile app or a portal with no field for it

⚠️ Don’t submit a weak cover letter just to check a box.

• Personalization – Address the hiring manager, mention the company’s mission
• Narrative – Explain transitions, goals, or enthusiasm
• Extra keywords – Boosts ATS visibility
• Differentiation – Shows effort and thoughtfulness
• Soft skills showcase – Demonstrates writing and communication skills

Great cover letters are:

• Customized for the specific company and role
• Less than 1 page
• Focused on what you bring to the table
• Written in a conversational yet professional tone

📌 Template approach doesn't work. Tailoring is key.

• Starting with “To Whom It May Concern”
• Regurgitating your resume
• Talking only about what you want
• Overusing buzzwords without proof
• Writing more than one page
• Failing to explain why you’re interested

“If the resume impresses me, I’ll check the cover letter to see how they think and write.”
— Amanda B., Tech Recruiter

“I love when someone explains why our mission matters to them. That connection sticks.”
— Kareem H., Nonprofit Hiring Manager

“A generic letter turns me off. If you're going to write one, make it matter.”
— Tanya R., Fortune 100 Recruiter
