How long should a cover letter be?
Three to four short paragraphs, under one page. Hiring managers skim — the goal is one memorable, relevant point, not completeness.
Do I still need a cover letter in 2026?
When a posting asks for one, yes — skipping it reads as low effort. When it is optional, a tailored letter is a cheap way to stand out; a generic one adds nothing.
What if I don't know the hiring manager's name?
"Dear Hiring Team" or "Dear [Team] Hiring Manager" is fine. Avoid "To Whom It May Concern," which reads dated.
Can I reuse one cover letter for every job?
Reuse the structure, not the content. The opening and proof paragraph should change per posting; that is where "written for this job" comes from.
