In the included example, a freelance consultant’s offer became 4 emails of 69, 36, 65 and 21 words, 6 subject lines and one reply ask per email.

Who it’s for
Built for agencies, freelancers and B2B founders who do their own outbound.

What breaks, and when
A long first email that ends with a calendar link reads like every other pitch, and it gets left unanswered.

What you get
• Sequence shape: days 1, 3, 8, 15 with body limits of 90, 60, 80 and 40 words
• Subject-line rules (2-4 words, A/B pairs), the personal-line test and the reply ask

Install in 30 seconds
Unzip into ~/.claude/skills/ (Claude Code) or upload it as a custom skill in the Claude app, then ask: “Can you write a 4-email cold sequence for my agency’s offer?”. Nothing to run.

What it does not do
It doesn’t send email or find leads, and it never invents numbers: it uses the proof you give it.

FAQ
Q: How is this different from asking Claude without the skill?
A: The skill carries a fixed method, fill-in templates and a full worked example, so Claude follows the same structure every time instead of improvising a new one.
Q: How do I get the files?
A: After paying, open it in your Whop library: in “Download — cold-email-sequence” the lesson “cold-email-sequence.zip” has the zip attached.
