Overview

Letterkeel is an MCP server that lets you send email from your own domain through multiple providers: SMTP, Resend, SendGrid, Mailgun, and Postmark. Connect it to Claude, Cursor, VS Code, or any MCP client to compose and dispatch messages on demand.

This is a hosted remote server at https://mcp.apify.com/?tools=cybermax/send-email&via=mcp-registry. Authentication requires an API key. Version v1.0.1 is the current release. No local installation needed — just point your client at the endpoint and you're ready to go.

Letterkeel appears in the Communication category on mcp.site and works with Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and other MCP clients. Maintainers can claim this listing to verify ownership and keep information up to date. Learn more at https://cybermaxtools.com/store/letterkeel-send-email/.
