Imagine Sarah, a software engineer, sending out 50 job applications with tailored cover letters. Yet, only a handful get responses. Why? The answer lies in how US ATS processes cover letters (what it extracts) and how that impacts the job application funnel. Many candidates overlook that applicant tracking systems (ATS) don’t just scan resumes—they also parse cover letters, often in surprising ways.
Understanding this process can dramatically increase your chances of landing interviews. This detailed guide will break down what ATS extracts from your cover letters, how recruiters and hiring managers use this data, and how to optimize your documents with actionable examples and templates from HireFlow.
Quick Checklist: Preparing Your Cover Letter for ATS Success
- Use standard fonts like Arial or Times New Roman – fancy fonts break parsing.
- Keep formatting simple: avoid tables, text boxes, and images.
- Include clear contact information at the top matching your resume.
- Incorporate key job-related keywords naturally within your text.
- Use common headings such as "Introduction," "Skills," and "Closing."
- Save and upload cover letters in ATS-friendly formats: typically .docx or .pdf (text-based).
- Match your cover letter’s tone and content with your resume for consistency.
- Proofread to avoid spelling errors that confuse ATS keyword matching.
How US ATS Processes Cover Letters (What It Extracts)
Applicant Tracking Systems are designed to scan large volumes of job applications quickly. While most applicants focus on resumes, ATS software also parses cover letters to extract meaningful data. But what exactly does it pull out?
1. Contact Information Extraction
ATS looks for your name, phone number, email, and sometimes LinkedIn URLs in the cover letter header. This data is cross-checked with your resume to ensure consistency. Inconsistent contact details can lead to confusion or lost communication.
2. Keyword Identification
ATS scans your cover letter for job-specific keywords—skills, certifications, tools, and action verbs. For example, if the job description emphasizes “React.js” and “Agile methodology,” the ATS looks for these terms in your letter. Keywords must be embedded naturally; keyword stuffing can backfire.
3. Sentiment and Tone Indicators
Some advanced ATS platforms analyze sentence structure and tone to gauge professionalism and enthusiasm. They flag overly generic or negative language, preferring confident, positive phrasing that aligns with company culture.
4. Structural Elements and Formatting
ATS detects headings, paragraphs, bullet points, and section breaks. Clear structure helps the system segment your letter for easier analysis. Poor formatting—like embedded images or complex tables—may cause the ATS to skip sections.
5. Customization Flags
Some ATS algorithms compare cover letters against the job description to identify customization. Generic cover letters without specific references to the company or role may be scored lower.
Understanding these extraction points allows candidates to tailor cover letters that get past ATS filters and into the hands of recruiters and hiring managers.
Mini Before/After: Optimizing a Cover Letter for ATS
Before Optimization
"Dear Sir/Madam, I am excited to apply for your job opening. I have lots of experience with software development and leadership. Please review my resume."
After Optimization
"Dear Hiring Manager, I am eager to apply for the Senior Frontend Developer role at Acme Corp. With 5+ years experience leading Agile teams and expertise in React.js and JavaScript, I am confident in driving innovative web solutions that align with Acme’s goals."
The second example includes specific keywords ("Senior Frontend Developer," "Agile teams," "React.js"), personalized company mention, and quantified experience—all signals ATS extracts and values.
Step-by-Step: How ATS Extracts Data from Cover Letters
- Upload and File Conversion: The ATS converts your cover letter file (PDF, DOCX) into plain text for parsing.
- Header Parsing: Extracts contact info and basic identifiers from the top section.
- Keyword Scanning: Searches for skills, qualifications, and role-specific terms matching the job description.
- Contextual Analysis: Uses algorithms to understand phrase relevance, avoiding false positives from keyword stuffing.
- Formatting Interpretation: Recognizes headings and bullet points to segment content logically.
- Customization Check: Compares letter content to job ad for tailored language and company mentions.
- Sentiment and Tone Assessment: Flags professionalism and enthusiasm levels via natural language processing.
- Data Integration: Merges extracted data with resume info to build a candidate profile.
- Ranking and Scoring: Scores cover letter relevance and quality to influence overall application ranking.
Common Cover Letter Mistakes That Hurt ATS Parsing
- Overly Fancy Formatting: Using tables, images, or decorative fonts that confuse ATS extraction.
- Generic Language: Lacking job-specific keywords or company references.
- Inconsistent Contact Details: Mismatched emails or phone numbers between resume and cover letter.
- Keyword Stuffing: Repeating keywords unnaturally, triggering ATS penalties.
- Submitting Wrong File Types: Uploading scanned images or non-text PDFs that ATS can't read.
- Ignoring ATS Formatting Tips: Not using standard headings or bullet points.
Avoiding these pitfalls improves the chances that your cover letter is correctly processed and positively scored by ATS, increasing visibility to recruiters.

How Recruiters and Hiring Managers Use ATS Cover Letter Data
Cover letters processed by ATS do not just vanish into a black hole. Recruiters and hiring managers rely on the extracted data in several key ways:
1. Candidate Ranking and Shortlisting
The ATS generates a composite score by combining resume and cover letter data. Candidates with high keyword matches and well-structured cover letters rise to the top of the shortlist, saving recruiters time.
2. Validating Candidate Fit
Hiring managers scan cover letter phrases to confirm the candidate’s motivation and cultural fit. Customization flags from ATS signal genuine interest versus generic applications.
3. Supporting Interview Decisions
Cover letter content, especially unique achievements and soft skills, can tip the scales when candidates have similar resumes. ATS-extracted data helps recruiters pick standouts.
4. Preparing Recruiter Notes
Recruiters often use ATS summaries to prepare talking points before interviews, relying on the parsed cover letter details to understand the candidate’s narrative.
Troubleshooting ATS Cover Letter Submissions: Common Issues and Fixes
If your cover letter isn’t yielding interview invites despite quality content, consider these troubleshooting tips:
- File Format Problems: Switch between .docx and text-based PDFs. Avoid scanned images.
- Hidden Formatting Errors: Remove tables, columns, and graphics. Use plain text formatting.
- Keyword Gaps: Re-examine the job description and add missing keywords naturally.
- Contact Info Mismatch: Ensure email and phone number match exactly between cover letter and resume.
- Generic Language: Personalize with company name and role-specific details.
- Length Issues: Keep cover letter concise—typically one page—so ATS can process it fully.
Addressing these factors will improve ATS readability and boost your chances of getting noticed by recruiters.
FAQ: How US ATS Processes Cover Letters (What It Extracts)
1. Do all ATS systems read cover letters?
Not all ATS platforms require or parse cover letters, but most major US ATS systems do if you upload one. Even when not mandatory, submitting a well-optimized cover letter can increase your score and visibility. It's best practice to treat the cover letter as a complementary document supporting your resume in the ATS ecosystem.
2. Can ATS detect if my cover letter is generic?
Yes, many ATS tools use natural language processing to identify generic phrases and lack of company-specific keywords. Cover letters that don’t mention the company name, job title, or role details may be flagged as generic, lowering your ATS score and reducing recruiter interest.
3. Should I include keywords in my cover letter like in my resume?
Absolutely. Incorporate relevant keywords naturally within your cover letter’s narrative to reinforce your qualifications. This synergy increases the likelihood that ATS will detect a strong match between your profile and the job description, improving your ranking during automated screening.
4. What file format is best for ATS-compatible cover letters?
The safest formats are text-based PDFs and Microsoft Word documents (.doc or .docx). Avoid scanned images or PDFs created from images, as these are not machine-readable. When in doubt, check the company’s application instructions or HireFlow’s recommendations for supported formats.
5. Can formatting like bullet points or headings help ATS read cover letters?
Yes. Clear formatting—such as headings, paragraphs, and simple bullet points—helps ATS segment and interpret your cover letter content. However, avoid complex formatting like tables or embedded graphics that might confuse the parser and cause data loss.
6. How do recruiters use the data extracted from cover letters by ATS?
Recruiters use ATS-extracted data to quickly assess candidate fit, rank applicants, and prepare for interviews. Cover letter insights complement resume data by highlighting motivation, communication skills, and cultural alignment. This helps recruiters and hiring managers decide whom to prioritize for further review.
