Claude Code · Cold email
Cold email from Claude Code
Lead Scorer exposes its whole outbound motion as an MCP server. Point Claude Code at it and cold email becomes something you ask for in a sentence instead of something you click through. The right host for repeatable runs — pair it with the downloadable skills and it drives the whole motion up to the approval step.
Go from an empty list to a reviewed email sequence without leaving the chat: pull real companies, resolve the decision-maker, write the messages, queue them for approval.

Paste one into Claude Code once the server is connected. No tool names required — it picks them.
- ›Find 50 SaaS founders in France with 2 to 10 employees, add them to a new list, and draft a cold email campaign for them.
- ›Take my list “Q3 fintech”, find contact emails for anyone missing one, and write a three-touch email sequence anchored on each company's business model.
- ›Read the drafts in my campaign “October outbound” and rewrite every one where the first line would work for any other company.
What Claude Code can do on cold email
- → Pull companies from the official French State registry (SIRENE + INPI RNE) filtered by NAF/APE code, headcount and département — every one carries a verified SIREN and a real dirigeant.
- → Find verified professional emails for the people worth writing to, and attach them to the lead record.
- → Read the campaign authoring context — your product, the lead's enrichment, the angle — before a single line is written.
- → Write the first touch and the follow-ups per lead, anchored on facts from the enrichment rather than generic openers.
- → Re-read its own drafts through the campaign action list and rewrite the ones that do not hold up.

Where you stay in the loop
