Open with why you're excited about this specific role, give one or two concrete examples of what you'd bring, and close by asking for the interview. Keep it to half a page and never reuse it word-for-word.
The three-paragraph formula
- Hook — name the role and one genuine reason this company interests you.
- Proof — one or two specific examples of relevant skills or wins (pull from your resume, don't repeat it).
- Close — restate your interest and politely ask to talk.
Make it specific
The fastest way to sound generic is to write something you could send to any company. Mention the actual role, a product you like, or something from the job post. One specific sentence beats a paragraph of buzzwords.
Warm and professional, like emailing a respected adult. Confident, not cocky. Enthusiastic, not desperate.
Common questions
Do I even need one?
If there's a field for it, yes — many hiring managers read it first. A thoughtful note is an easy way to stand out.
How long?
Half a page, three or four short paragraphs. They're busy.
