Raechly MCP

Run cold email from your AI app: mailboxes, warmup, lead search, campaigns, replies and deals.

Raechly is a hosted MCP server at https://mcp.raechly.com/mcp. Connect it to Claude, ChatGPT, Cursor or any MCP client and run outbound by asking: set up sending domains, warm mailboxes, find leads, write the sequence and handle replies.

This repo holds the install files for Claude Code, Codex, Cursor and other clients. The server itself is hosted by Raechly, so there is nothing to run.

What you can ask

"Suggest 3 sending domains for my company and set up 2 mailboxes on each with warmup."
"Find 200 heads of finance at US SaaS companies with 50 to 500 staff and add them to a lead list."
"Write a 4-step campaign for that list about our invoice automation tool and show me the emails before anything sends."
"Show today's replies, mark the interested ones and draft answers to their questions."
"How did last week's campaign do? Open rate, replies and meetings booked."
