Connect to Sarbacane email marketing platform to read campaigns and statistics, manage contact lists and custom fields, view blacklists and unsubscribers, and draft new email campaigns. Campaigns created are saved as drafts and must be sent from Sarbacane.

Example request: "Show me the open and click rates for my last email campaign and add these new contacts to my subscriber list."

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use Sarbacane to help me. It is a free service with an MCP server at https://sarbacane.usefulapi.io/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.
