    Email Marketing MCP Server for Claude, ChatGPT & Cursor

    The IGSendMail MCP server is an open-source connector that lets AI assistants manage your email marketing through the Model Context Protocol. Ask Claude to add a subscriber, pull last week's campaign stats, or draft a newsletter to a list, and it happens in your IGSendMail account with your own API token. It is free on every plan, including the free plan.

    • “Import these 200 leads into the Webinar list and tag them webinar-sept.”

    Frequently Asked Questions

    An MCP (Model Context Protocol) server is a small program that exposes a product's capabilities as tools an AI assistant can call. IGSendMail's MCP server exposes your lists, subscribers, campaigns and automations, so Claude, ChatGPT or Cursor can read your stats, add contacts or draft a campaign when you ask in plain English, using your own API token.

    Any client that supports MCP: Claude Desktop, Claude Code, Cursor, Windsurf, VS Code with Copilot agent mode, and ChatGPT through its connectors using the hosted endpoint. Local clients run the server with npx; hosted clients connect to mcp.igsendmail.com with your API token as a bearer token.

    Yes. It is MIT-licensed, open source, and available on every IGSendMail plan including the free plan. You only need an API token from your account settings. Usage counts against the same sending and subscriber limits as the web app, nothing extra.

    No. Creating a campaign only makes a draft. Sending, deleting, unsubscribing and triggering automations require an explicit confirm flag and are marked destructive in the tool metadata, so compliant clients ask you before running them. The server never acts on its own; it only responds to tool calls your assistant makes.

    Add or import subscribers with custom fields and tags, search your lists, create and edit lists and merge fields, draft campaigns from HTML, launch, pause or resume them, pull full campaign statistics including opens, clicks, bounces and top links, and trigger automation workflows. Thirty-two tools in total, all documented in the package README.

    Locally the token lives in your MCP client's config and is sent only to mail.igsendmail.com over HTTPS. The hosted endpoint is stateless and reads the token from the Authorization header of each request; nothing is stored. You can revoke and regenerate the token at any time from Account → API token.
