Unisender Mcp

Connects Claude to the UniSender email marketing platform with API key authentication. Exposes 10 tools covering list management (create lists, get subscriber counts), contact operations (subscribe users, fetch contacts by list), campaign workflows (create emails, send campaigns, check delivery stats), and template retrieval. Includes two composite skills that chain operations together: one for the full send flow from list to delivery, another for pulling complete campaign analytics. Useful when you're managing email campaigns programmatically and want Claude to handle subscriber management, campaign creation, or pull performance metrics without jumping into the UniSender dashboard. Runs via stdio or as an HTTP server for streamable responses.
