Should you always include a cover letter? The answer isn't as straightforward as you might think. While cover letters can strengthen your application, there are situations where they add little value — or even hurt your chances. Here's how to decide.
The application requires one. This seems obvious, but many applicants skip required cover letters. If the system says "cover letter required" and you don't submit one, your application may be automatically rejected.
You're making a career change. A cover letter is your best opportunity to explain why you're switching industries and how your transferable skills apply. For more on this, see How to Write a Career Change Cover Letter.
You have an employment gap. Address the gap directly and positively. Explain what you did during that time — whether it was education, caregiving, health, or personal projects.
You're applying to a small company. Smaller companies with fewer applicants are more likely to read cover letters carefully. A personalized letter can make a strong impression.
You have a referral. If someone referred you, mention it. Referrals significantly increase your chances of getting an interview.
The application system doesn't accept them. Some ATS platforms don't have a cover letter field, and uploading one as an attachment won't be read.
You're applying to dozens of similar roles via easy-apply platforms. In high-volume applications where hiring managers rarely read cover letters, your time is better spent customizing your resume.
The job posting explicitly says not to send one. Respect the instructions.
If a cover letter is optional but you're unsure, write a short three-paragraph version. A concise, well-written letter is better than a long, generic one. It shows effort without demanding too much of the reader's time.

Most ATS systems do not parse cover letters for keywords the way they parse resumes. Your cover letter won't significantly affect your ATS score. However, if a human recruiter opens your file and sees a cover letter, it can help tip the scales in your favor.

Not sure if your cover letter helps? Read it honestly. If it's generic, vague, or full of clichés, it's better to skip it entirely or rewrite it. A bad cover letter actively hurts your chances by signaling low effort.
