How long should a cover letter be?
Three to four short paragraphs on a single page, totalling 250 to 400 words. Hiring managers skim, so density matters more than length. The opening should state the role you are applying for, the body should connect two or three of your achievements to the job requirements, and the closing should request an interview and thank the reader.
Do I need to address the cover letter to a specific person?
Wherever possible, yes. A name shows you researched the company and is more engaging than "Dear Hiring Manager." Check the job ad, the company website, or LinkedIn for the recruiter or department head. If you genuinely cannot find a name, "Dear Hiring Manager" or "Dear [Department] Team" is acceptable. Avoid the dated "To Whom It May Concern."
Should the cover letter repeat what is on my resume?
No. The resume lists what you did; the cover letter explains why it matters for this specific role. Pick two or three accomplishments from your resume that map directly to the job description, then expand on them with context, scale, and outcome. A cover letter that simply summarises the resume is a wasted page.
Are cover letters still expected in 2026?
It depends on the role and country. In the US, UK, and Europe, around 60 to 70 percent of employers still read cover letters when supplied, especially for senior, creative, and customer-facing roles. Tech roles often skip them. When the application form has a cover letter field, fill it. When in doubt, include one - it rarely hurts.
How do I open a cover letter without sounding generic?
Skip phrases like "I am writing to apply for..." Lead with a hook: a quantified result from your last role, a specific reason you admire the company, or a direct connection between your skills and a challenge mentioned in the job ad. The first sentence decides whether the reader continues, so make it specific to this job.
Can I reuse the same cover letter for multiple jobs?
You can reuse a base structure, but every cover letter should mention the specific company name, role title, and at least one detail unique to that posting. A copy-pasted letter is easy to spot and signals low effort. Use the builder to save your base draft, then spend five to ten minutes tailoring the middle paragraphs to each new application.
