Do You Even Need a Cover Letter Anymore
If the application has a cover letter field — yes. If it's optional, the answer is still usually yes for any role you actually want. Cover letters give you the one chance to add context a resume can't: why this role, why this company, why now. Skipping it signals low effort. The exception: roles that explicitly say 'no cover letter' or applications where you have a strong referral and the recruiter has indicated they don't need one.
The Structure That Works
Open with a sentence that signals fit and shows you understand the role — not 'I'm writing to apply for the X position' (the recruiter knows what role you applied to). Second paragraph: connect your most relevant experience to the job's core requirements with one specific example. Third paragraph: show you understand the company beyond the job posting — a recent product launch, a strategic direction, a value that resonates. Close with a confident, specific ask: a conversation about how you can contribute to the specific work the team is doing.
Length: Shorter Than You Think
Three short paragraphs. Maximum one page, but ideally half a page. Recruiters skim cover letters even more than resumes. Long cover letters get scanned for keywords and discarded. Tight cover letters get read.
What to Avoid
Generic openings ('I am writing to express my interest...'). Restating your resume in paragraph form. Discussing what the job will do for you ('this role would be a great opportunity for my growth') instead of what you'll do for them. Apologizing for gaps or weaknesses. Listing every relevant qualification — pick one or two and make them count. Cliché phrases ('hit the ground running,' 'team player,' 'passionate'). Calling yourself the 'perfect candidate.'
How to Customize Without Starting From Scratch
Build a cover letter template with a fixed structure and three variable sections: opening hook, relevant experience example, and company-specific paragraph. For each application, only the variable sections change. This lets you write a tailored letter in 15-20 minutes instead of starting blank every time.
When to Address Gaps or Concerns
If you have an obvious red flag (career gap, industry change, lack of typical credentials), address it briefly and confidently in the cover letter — not the resume. One sentence acknowledging the situation, one sentence framing why it makes you a stronger candidate. Don't dwell. Don't apologize. Frame the narrative on your terms.
