How to Set Up Your Muse Email

Muse Mail is the dedicated email address Meta announced for Muse at its Connect conference on September 23. It gives your agent an address of its own, so you can add it to an email thread or forward things for it to handle. The rollout is reaching users in waves, so the first step is checking whether the feature has arrived for you. If it has, setup takes a few minutes.

Check Whether You Have It

Open Muse and look for a card headed “Give your Muse its own email,” with a Setup button. The rollout is reaching users in waves, and Meta has not announced a schedule or said who gets it first. If the card is not there, the feature has not reached you yet. There is no setting that turns it on, and reinstalling the app does not help. Check again in a few days.

If the card isn’t showing, ask Muse directly. For example, Aaron Makelky posted that his mailbox was already available before he knew it, and he only found out by asking Muse to turn it on. His screenshot confirms the setup flow in this guide: the card reads “Give your Muse its own email,” with a Setup button, and Muse says it will check once you’re done. He also says the feature gives you a UI for the inbox, though his screenshot shows only the setup card, not an inbox list.

Set It Up in Three Steps

1. Tap Setup on the card. Muse creates the mailbox.
2. Tell Muse you’re done. The agent checks that the mailbox is live.
3. Ask Muse for your address and save it somewhere you can find it, such as your notes app or password manager.

That is the whole flow as users have seen it so far. Meta has not published official setup steps, so the card and the agent’s own confirmation are the guide.

What Your Address Looks Like

Addresses appear to end in @muse.ai, with a handle of 3 to 32 lowercase letters, digits, or hyphens. That format comes from RuntimeWire’s static inspection of the Muse app before launch, and Meta has not confirmed it. Treat it as a useful hint. Whatever Muse tells you your address is, that is your address.

Copy-Paste Prompts

Use these word for word, or adapt them to your setup.

I tapped Setup on the Muse Mail card. Check whether my mailbox is live and tell me my email address.

My Muse Mail address is [your address]. From now on, use it when you contact anyone on my behalf, and keep my personal email out of it.

Check my Muse Mail inbox for anything new and summarize it in three bullets.

A Named Setup: The Moving-Quote Inbox

Maya is moving house and wants quotes from three moving companies without putting her personal address on three more mailing lists. She taps Setup on the Muse Mail card, tells Muse the mailbox is ready, and asks for the address. She gives the Muse address to all three companies. The quotes land in Muse’s inbox, not hers, and Muse pulls the prices into one comparison she can read in a single message. Her personal inbox never sees the thread.

What Can Go Wrong

Muse says the mailbox isn’t live yet. Setup can take a while to propagate, so wait a few minutes and tell Muse to check again. If it still isn’t live after a day, tell Muse the exact message you see on the card and let it work from that. A second snag is that the handle you want may already be taken. Handles have to be unique, so pick a variation, add a word that describes the job, and move on.

How Muse Mail Differs From the Gmail Connector

The Gmail and Outlook connectors connect Muse to accounts you already own. Muse Mail gives the agent an address of its own, so other people can write to Muse directly. Use the connectors when you want Muse to read your own mail, and use Muse Mail when you want mail to reach the agent without passing through your inbox. Connecting Muse to your apps covers the connectors, and inbox triage shows how Muse works through your own mail once it is connected.

One more option, separate from Meta’s feature, is third-party agent-email services such as AgentMail, Dead Simple, Email Bump, and Carly, which sell inboxes that work with Muse through a custom connector. They exist for people who want an agent address now, while Muse Mail is still rolling out. They come from other companies, and their setup runs through their own accounts and API keys.
