A cover letter structure that works
- Opening (2–3 sentences): the role, and one specific reason you fit or want it.
- Evidence (1–2 paragraphs): two examples mapped to the ad’s top requirements, each with a result.
- Why them: something true and specific about the team, product or mission.
- Close: a one-line summary of fit and availability. Skip “I look forward to hearing from you at your earliest convenience”.
Your resume carries the facts; the letter connects them to this job. Check the resume itself with the ATS resume checker.
Questions people ask
How long should a cover letter be?
Usually 250–400 words, three or four short paragraphs, and never more than one page.
Do applicant tracking systems read cover letters?
Many systems store the cover letter with your application, and a recruiter may read or search it. It is less standardised than the resume, so write it for the human reader first.
What should a cover letter include?
Why this role and company, two or three concrete examples that match the job’s main requirements, and a short close. Address a named person if you can find one.
Is my cover letter stored?
The basic checks run in your browser. If you ask for AI feedback, the text is sent once to an AI model through Vercel AI Gateway and not saved by ResumeATS.
