A cold email to a busy person has seconds to work. A Boomerang study of more than 40 million emails found that short emails, about 50 to 125 words, were answered about half the time. Here is a four-line structure and a prompt that makes Claude write it for you.
The four lines
- Line 1, who you are: your name and what you do, in one sentence.
- Line 2, your proof: one real result, number or name they will recognise.
- Line 3, one ask: a single, specific thing, like a 15-minute call.
- Line 4, an easy yes: make replying take five seconds, like "Reply 'yes' and I'll send times."
