Free Tool · Claude Skill

Cold email copy, written the way we write it for clients.

Install once. Say “write cold email copy for [website]” in any Claude chat. It researches first, then walks you through it step by step — direction, subject line, body, final copy — confirming at each stage instead of dumping a wall of text you throw away. You end up with a campaign you actually send.

Read the site. Before I write, let me confirm direction.

Target: Heads of People at 200-1,000 person tech. Pain: onboarding drags for weeks. Angle: cut time-to-productive, not headcount. Proof: Ripp:l cut onboarding 40%. Work?
You
yes, go

Body structure — value prop → one proof point → soft CTA, with {{recent_hire_signal}} personalization. Approve?

Final copy: email 1 + 2 follow-ups, all variants, ready to paste. Spintax applied, opt-out line in, no links in email 1.
The four steps

A stepwise flow, like a Typeform. You confirm the direction before the copy, so the final draft is one you already agreed with — not a lucky first guess.

01
Confirm direction

It researches your site or brief silently, then hands back the target, core pain, value prop, and proof point in one screen. You approve or adjust before a single line gets written.

02
Subject + first line

Two or three complete options, each a different strategy — observation-led, trigger-led, direct — with a recommendation and why. You pick.

03
Body structure

Value prop, which case study to lean on, the AI personalization variables, and CTA style — confirmed before the full draft, so the copy lands where you expected.

04
Final copy

Email 1 plus follow-ups, every variant, ready to paste. Spintax applied, opt-out line in the body, no links in the first email — the way we ship it for clients.

Want the strategy behind the copy?

Great copy is the last 10%. Infrastructure, targeting, and sequencing are the other 90% — and where campaigns actually get won or lost. That’s what we run for clients.
