ChatGPT · Cold email

Cold email from ChatGPT

Lead Scorer exposes its whole outbound motion as an MCP server. Point ChatGPT at it and cold email becomes something you ask for in a sentence instead of something you click through. The one to pick if your day already runs in ChatGPT and you would rather not open a second dashboard.

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.

Connect ChatGPT

OAuth — ChatGPT discovers the flow from the server and hands you the Lead Scorer sign-in. Runs in chatgpt.com with developer mode enabled.

Three prompts to start with

Paste one into ChatGPT 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 ChatGPT 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

Drafts land in your approval queue. No email leaves an inbox until you approve it, and you set the daily cap and the sending window.

What is ChatGPT?

ChatGPT is OpenAI's assistant. Developer mode lets you register a remote MCP server as an app, after which its tools are callable from an ordinary chat.

Built by OpenAI.
