Email Inbox for Meta Muse: Documents and Sign-In Emails
Muse is Meta’s personal AI agent. It does tasks for you on a cloud computer of its own, in the Muse app for iOS and Android and on the web. Meta started Muse in the United States in September 2026, and in Singapore in October 2026. Muse Spark is the Meta model behind it.
Meta’s help pages describe no email address for Muse itself (checked 2026-11-12). Muse gets your documents and email in three ways: files that you upload, an email account that you connect, and the Mail app on a Mac. This guide shows each way, and how to keep documents and sign-in emails apart from the rest of your mail.
Upload documents in the conversation
Attach the file to your message in a Muse conversation, then ask your question. Muse can summarize the file or answer questions about it. It can also use files from earlier in the same conversation (Meta Help: How to use Muse with artifacts).
Muse reads these file types:
- documents: PDF, DOCX, plain text and Markdown;
- spreadsheets: XLSX and CSV;
- images: PNG, JPEG, GIF and WebP.
Muse saves the files that it makes in the Library tab. For one quote or one receipt, an upload is the fastest way. No mailbox is necessary.
Connect your email account
Muse uses connectors (links to Meta apps or to other apps) to work with your accounts (Meta Help: How Muse works with connectors).
- In Muse, open Settings > Connectors.
- Find Gmail and select Connect. You can also ask Muse: “Connect my Gmail.”
- Sign in to your Google account and complete the authorization steps.
- Ask Muse: “Find the newest email with a PDF attachment and summarize the PDF.”
When you connect email, you choose whether Muse only reads your mail or can also send email for you (Meta Newsroom). By default, Muse asks for your approval before it sends an email.
Use a separate inbox for documents and sign-in emails
When you connect your main mailbox, Muse can search all of your mail. To limit what it reads, give it a separate inbox. We recommend a separate Gmail account, because it is free and Muse has a Gmail connector. Email inboxes for AI agents and people lists other services, with prices.
- Create a new Google account with a Gmail address (Gmail Help: Create a Google Account for Gmail).
- In your main Gmail, open Settings > See all settings > Forwarding and POP/IMAP, and add the new address as a forwarding address.
- Open the verification email in the new account and click the link.
- In your main Gmail, create a filter for each sender, for example a contractor. Select Forward it and choose the new address (Gmail Help: Automatically forward Gmail messages).
- Connect the new account to Muse, not your main account.
Use the new address for sign-up emails of accounts that you own and that you let Muse use. Keep account recovery on your own email address.
Muse on a Mac: the Mail app
The Muse app for Mac can work with apps on your Mac, such as Mail. For each app, you choose Off, Read only or Read and interact. Muse also needs the macOS permissions Full Disk Access and Automation (Meta Help: How Muse works with files and apps in your Mac).
If Muse only reads your documents, choose Read only for Mail. To change the access later, open Settings > File System Access in Muse.
Email services that are not in the list
If your email service is not in the list of connectors, you can ask Muse to create a custom connector. Muse guides you through the steps, which can include the API information of the service. Muse keeps the credentials in its Secure Credentials Store.
Meta does not review custom connectors or how they use your information. Connect only a service that you trust, and give it the smallest access that the task needs.
Set when Muse asks you first
Meta’s help describes two approval settings (Meta Help: How Muse works with your guidance and approval):
| Setting | Muse asks you before |
|---|---|
| Ask for some actions | every write action, for example a sent email, and important read actions |
| Always ask | every action |
When Muse asks, you can allow the action once, allow it for the task, allow it for a site, always allow it for a connector, or deny it. A sent email cannot be undone, so allow email sending once at a time.
Three small uses
- Contractor quotes. Forward the quote attachments to the separate inbox, or upload them. Ask Muse to compare the prices, the proposed dates and the exclusions. Example: €900 for October 15 and €1,050 for October 10. Muse can show that the earlier date costs €150 more.
- Sign-up emails for a research tool. Receive the confirmation email or sign-in link for an account that you use. Tell Muse not to put codes or links in summaries.
- Order receipts. Collect receipts in the separate inbox. Ask Muse for a list of merchants, dates and totals, and keep the original emails to compare.
A prompt to compare quote PDFs
Use only the emails from contractors in my connected Gmail. Make a table of the quote PDFs with these columns: contractor, total price, proposed date and exclusions. Name the source email and attachment of each row, with the PDF page number when you can. Flag missing or unreadable details. Do not guess.
Your data in Muse
Muse keeps the files that you upload. The setting Help improve our AI models in Settings > Data controls is on when you start to use Muse. If you do not want Meta to use your conversations to improve its AI models, turn it off before you upload private documents (Meta Help: How to manage your Muse data).
