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.

The worked example it ships

COLD EMAIL SEQUENCE — HubSpot pipeline cleanup → VP Sales at B2B SaaS (20-80 people)
Sender: Marcus Hale, freelance HubSpot consultant · first prospect: Dana Whitfield, VP Sales, Northbeam (55 people) · trigger: 2 AE roles posted in August · plain text, no links

1) SEQUENCE MAP — 4 emails over 15 days, one reply ask
Email 1 · day 1 · new thread | 2 AE roles → no next step → 31% to 6% → reply question
Email 2 · day 3 · new thread | forecast call 90 to 35 minutes → same question, shorter
Email 3 · day 8 · new thread | a 5-minute HubSpot check → Reply CHECKLIST
Email 4 · day 15 · new thread | last email → now, next quarter, or no

2) SUBJECT LINES — 6 lines
Email 1 · A | two new AEs
Email 1 · B | Northbeam pipeline
Email 2 | 31% to 6%
Email 3 · A | forecast call length
Email 3 · B | one HubSpot report

Install

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.

Ask Claude

“Can you write a 4-email cold sequence for my agency's offer?”

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

What is a Claude skill?

A folder with a SKILL.md, a method, fill-in templates and a worked example. Claude loads it when your request matches and follows that method instead of improvising.

How is this different from asking Claude without the skill?

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.

What does it not do?

It doesn't send email or find leads, and it never invents numbers: it uses the proof you give it.

How do I install it?

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.
