How to write a cold email
A cold email earns a reply by being about the prospect, short, and easy to say yes to. Most cold emails fail because they open with the seller, run long, and ask for too much. The winning formula is relevance plus brevity plus a single small ask.
Short answer
Write a cold email by researching one specific trigger about the prospect, opening with them not you, stating a relevant problem you solve with proof, and closing with one low-friction ask. Keep it under 100 words, make the subject line short and specific, and send from a real person. Personalize the first line, template the rest.
Step by step
Research one specific trigger
Find a real reason to reach out now: a role change, funding, a job posting, a product launch. One specific observation beats generic flattery.
Write a short, honest subject line
Keep it to a few words, specific and not clickbait. Lowercase, question, or a relevant reference often outperforms polished marketing copy.
Open about them, then state the problem
Lead with the prospect and a problem you know their role faces, not your company. Add one line of proof or a peer result.
- Line 1: personalized trigger about them
- Line 2: the relevant problem
- Line 3: proof (a peer result or metric)
- Line 4: one small ask
Make one low-friction ask
Ask for a small yes: openness to learn more or a brief call, not a 30-minute demo from a stranger. Lower the bar to reply.
Keep it under 100 words and mobile-friendly
Short paragraphs, one idea, no attachments. Most cold emails are read on a phone in seconds.
Common mistakes
Opening with "I am reaching out because we are the leading..." No one cares about you yet. Earn attention with relevance to them first.
Asking for a 30-minute meeting in the first email. The ask is too big for zero trust. Start with a smaller yes.

Frequently asked questions
How long should a cold email be?
Under 100 words, ideally 50 to 75. Cold emails are read fast, often on a phone. Every extra sentence lowers reply rates. Say one relevant thing, offer one proof point, and make one small ask, then stop.
What makes a good cold email subject line?
Short, specific, and honest, usually a few words that reference something real about the prospect. Lowercase and question-style subjects often beat polished marketing copy because they feel personal. Avoid clickbait that the body cannot deliver on.
Should I personalize every cold email?
Personalize the opening line with a real trigger about the prospect, and template the rest. Full manual personalization does not scale and full templating gets ignored. The hybrid, one genuine personalized line plus a proven frame, gets the best reply rate at volume.
