Connect to your Rapidmail email marketing account to read recipient lists and subscribers, view newsletter performance stats, check delivery activity, and manage individual subscriber records. Muse can help you look up subscriber details, add new subscribers with opt-in, update subscriber info, and unsubscribe people.

Example request: "Show me the open and click stats for my last newsletter campaign."

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use Rapidmail to help me. It is a free service with an MCP server at https://rapidmail.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.

- rapidmail_get_recipientlist: One recipient list by id. GET /recipientlists/{id}.
- rapidmail_get_recipientlist_activity_stats: Subscription activity of one recipient list between two dates (for example new subscriptions and unsubscriptions).
