The Claude Code Cold Email System

Your whole cold email system, run by Claude Code for you.

Domains, mailboxes, warm-up, lists, copy and replies. 37 lessons and a Claude Code system that remembers your business, writes in your voice, and handles all the work.

One time · every dollar you've already spent with me comes off

A system you run, with the lessons behind every step.

No agency retainer.

No paid lead database.

No DNS headaches.

No copy that sounds like AI wrote it.

You won't have to set up domains, mailboxes and authentication by hand. Claude does the clicking and checks its own work.

You won't have to rent a lead database. You'll build lists from free public data the paid ones don't have.

You won't have to write every email and every reply yourself. Claude drafts them in your voice, for your approval.

Claude Code handles all the work, and it stops to ask before it spends a dollar.

What the system has built

A few of the lists the system's lead sources have produced:

YouTube creators in a niche, with verified emails
Contractors pulled from public permit records
Local businesses confirmed to be running ads right now
A messy CRM reconciled into a sendable list
Built to replace what you'd otherwise pay for
Crunchbase
BuiltWith
PitchBook
StoreLeads
D7 Lead Finder

Why I'm the one who built it

When I started my first business, every one of my early clients came from cold email. Every one of my businesses has grown from cold email. Later I built a cold email agency that grew quickly and ultimately got acquired in 2026.

A few months later, Claude Code could connect to every tool we used. Automations that took my team days to build, Claude now does naturally. So I built something that wasn't possible before: a system in Claude Code you can run yourself for the cost of the tools.

ChannelAverage B2B cost per leadWho you get
LinkedIn ads$202Whoever clicks and fills out the form
Meta ads$145Whoever the algorithm finds, bots and junk included
Your cold email setupabout $16 per interested replyOnly the companies and people you chose

Your tools run about $247 a month, plus about $97 for contacts: about $344. At 1,000 emails a business day and 1 interested reply per 1,000, that's about 22 interested replies a month, or about $16 each.

If you're thinking…

"I'm not technical."

You don't need to be. Claude does the technical work, tells you in plain words what it did, and stops to ask before it spends money or changes anything.

"Doesn't cold email just land in spam?"

It does when the setup is wrong, which is why so much of the system is authentication, warm-up and deliverability checks.

"What else will I pay for?"

A paid Claude plan, plus your sending tools: about $247 a month at full volume, and about $97 for contacts.

"I bought one of your $17 or $12 products."

Every dollar you've already spent with me comes off.

This is for you if

You sell to businesses, you want your own cold email system rather than renting an agency's.

It's not for you if

You want to put in zero work. If that's you, I can build it for you instead. See Build & Release →
