Cold email engine from Claude Code (100k/month)

You can now launch 100k+ emails / month from claude code and get +3% reply rates.

I open-sourced our Cold Email OS.

I've been doing cold email outbound for 3 years. Booked hundreds of calls for clients and myself from it.

Now I'm launching campaigns in 30-40min.

Every action is an endpoint, a CLI, or an MCP command the agent can call.

- Domain buying - Inboxes set up - warm-up - lead sourcing and signal sourcing - waterfall enrichment and verification - AI variables for personalisation - Sequencer set up with copy and lead enrollment - CRM Sync

All I do is review the end state before launching

UI is dead. Cold email is just a few MCP calls now.

I broke the whole thing down in a video masterclass. For the people who'd rather read than watch, there's a Notion doc. You also get the skills repo we actually used to build it.

If you want all 3:

and I'll send it over :)
