Connect guide

Connect your email to Muse

Updated 29 October 2026

Muse, Meta's personal AI agent, can read, search and reply to your email through Mailopoly. Connect your mailbox to Mailopoly, ask Muse to add Mailopoly as a custom connector, sign in and ask. One connection covers every account you own — Gmail, Outlook, Yahoo, iCloud and any IMAP mailbox — and on a paid plan your Slack, Teams, WhatsApp, Instagram, Messenger, TikTok and X messages too.

Muse can reach the apps in its own connector list. Mailopoly is the route to your mail as a whole: one connector that gives Muse everything that reaches you, already sorted. Every address you own is searched in one pass, Cleanbox separates the mail you'd want to read from the promotions, invoices and events are extracted on arrival, and replies go out from whichever address the conversation belongs to.

Mailopoly is going through Meta's connector review. Until it's listed, you add it as a custom connector — one sentence in a chat, then a sign-in. Nothing changes on the Mailopoly side when the listing goes live.

Setup is the same three steps for every provider. The only part that changes is how your mailbox connects to Mailopoly: Gmail and Outlook use a Google or Microsoft sign-in, and most other providers use an app password you generate in your account's security settings. Pick your provider below for the exact steps.

Pick your email provider

Each guide has the exact steps for connecting that provider to Mailopoly, example prompts and the things that go wrong. The Muse side is the same for every provider and is below.

Messaging channels — paid plans

On a paid plan, Muse gets your business channels through the same connection: read a week of a channel, find a message, reply back out through it. Pro and Business include channels; Single, Duo and Unlimited add them as app connections. The free trial covers email only.

How to add Mailopoly to Muse

Add Mailopoly to Muse

Open a chat in Muse — on the web or in the app — and ask it to create a custom connector for a remote MCP server called Mailopoly at `https://fastapi.prod.aws.mailopoly.com/mcp-server/`. Muse walks you through the rest.
Sign in with your Mailopoly account when prompted, then choose what Muse is allowed to do. Reading, making changes and sending are separate permissions.
Back in a chat, ask.

Mailopoly is going through Meta's connector review. Until it appears in Muse's connector list, Muse takes it as a custom connector — the same connection, added with one sentence instead of a tap. Muse connects from Meta's cloud, so there's nothing to install.

Whatever you've connected to Mailopoly is what Muse can reach. Reading, making changes and sending are separate permissions, and you can revoke Muse at any time from Settings → Security in the Mailopoly app — see the security page and the Mailopoly MCP page for other clients.
