## Research notes
Vendor's own MCP docs state the MCP server is a paid service with no free tier. Smaller/lesser-known player than most others in this sweep, but has a real vendor-hosted, documented MCP server - more than several larger competitors (Klenty, Outplay, Mailshake, QuickMail) have. 2026-09-07: https://mcp.supersend.io/mcp returned 401 with a JSON-RPC body: {"jsonrpc":"2.0","error":{"code":-32001,"message":"Missing or invalid credentials. Use Authorization: Bearer <key> or X-Supersend-Api-Key: <key>..."}} (https://mcp.supersend.io/mcp).
