Sendlet

Overview

Sendlet is a Model Context Protocol server that lets AI agents send emails only to people you've pre-approved. Each recipient or group gets a unique private MCP URL, so any MCP-compatible assistant can call Sendlet's tools directly within conversations or agent workflows.

It runs as a remote hosted service at https://sendlet.email/mcp/{endpoint} with no local installation required. The latest release is v1.0.0, and it needs no authentication to connect.

Sendlet is categorized as AI & Agents on mcp.site and integrates with all MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain Sendlet, you can claim this listing to verify ownership and keep the information up to date.
