Cover letters have long been considered optional, outdated, or a formality. But in an era where hiring starts with a machine scan, do they still have a purpose? And can they help you get past ATS systems?
The short answer is yes. But only if they’re written strategically.
This guide breaks down how to write a cover letter that aligns with ATS requirements while still delivering value to a recruiter who might read it next.
Do ATS Systems Scan Cover Letters?
Some do, some don’t. It depends on how the employer has configured their software. Many ATS platforms allow recruiters to filter by resume match first and review cover letters second. Or not at all.
However, when a cover letter is parsed, the system will scan it for keywords the same way it scans your resume. This makes it a secondary but useful way to reinforce your fit for the role.
Even when it’s not parsed, a well-written cover letter can build interest and context for your application. It’s your chance to add detail that doesn’t fit neatly into bullet points.
When a Cover Letter Actually Helps
- You’re changing industries or job functions. A cover letter can explain the why behind your transition.
- You have non-obvious but transferable experience. You can highlight connections that may not be clear on your resume.
- You’re applying to a company you admire. Personalizing your interest in their mission can set your application apart.
- You want to add context to a gap or career pivot. Resumes are limited. Cover letters can fill in the blanks.
How to Write a Cover Letter That Works for ATS
1. Use a Standard Format
Avoid templates with columns, tables, or visuals. Keep it left-aligned and text-based. Include:
- Contact info
- Date
- Hiring manager name (if known)
- Company name and job title
2. Mirror the Job Description Language
Just like your resume, the cover letter should reflect the job’s language. Use specific phrases and skills mentioned in the posting. This reinforces relevance for both ATS and recruiters.
3. Focus on One or Two Key Stories
Don’t restate your entire resume. Choose one or two examples that illustrate your qualifications and impact, and explain why they matter for this specific role.
Example: “In my previous role at Beacon Analytics, I led the migration of over 200 client records to a new CRM platform, improving data access and cross-team visibility. This project directly reflects the data management and collaboration skills outlined in your posting.”
4. Show That You Understand the Role
Use a few lines to reflect what the company needs and how you plan to meet that need.
“I understand you’re looking for someone who can manage end-to-end campaign execution while improving team workflows. That’s exactly what I focused on in my last role at a fast-growing SaaS startup.”
5. Keep It Concise
Aim for three short paragraphs or under 300 words. The goal is clarity, not formality. Focus on what matters most.

Final Thoughts
Cover letters are not always required. But when done well, they can bridge the gap between your resume and your story. They’re especially valuable when:
- You need to explain something
- You want to show enthusiasm
- You want to highlight alignment that might not be obvious
If your resume says “what,” your cover letter can say “why.”
And in a system that often filters out nuance, that might be exactly what gets you through.
