How to Use Muse to Find Important Emails
Use Muse to dig buried confirmations, receipts, and school or medical emails out of your inbox. Includes search prompts and what Muse can't promise yet.
Can Muse Do This?
Muse, Meta's personal AI agent, does some of its safest work on read-only jobs, and search is exactly that: you connect your email with read access, describe what you're hunting — a lost flight confirmation, a year of receipts, every message from your kid's school — and Muse can sweep the connected account, including attachment contents where it can read them. What separates this from your mail client's search box is that Muse understands intent rather than keywords, so 'anything about Maya's medication' can catch the pharmacy reminder, the pediatrician's note, and the insurance explanation, not just messages containing one word. Because it works asynchronously, a long sweep can finish after you've closed the app. The limits: Muse only sees the account you connected, deep searches of years of mail may take a while or occasionally stall given launch-week reliability reporting, and you should verify any message it surfaces before acting on it.
- Muse can only search mail in accounts you actually connected — nothing in other inboxes or in offline folders will be found.
- Launch-week agents sometimes fail to finish long jobs; for a multi-year sweep, split the range into chunks.
- Treat results as leads: open and confirm each message yourself before filing taxes, disputing a charge, or acting on medical mail.
How to Ask Muse
- 1
Connect email read-only
A search never needs send access. Read-only guarantees the sweep changes nothing, which is exactly the risk profile you want for archival digging.
- 2
Describe the thing, not the keyword
Instead of guessing what words the sender used, describe the event and the people: 'the confirmation for the school physical in August' beats searching 'appointment' and wading through noise.
- 3
Bound the range and senders
'Between June and August, from anyone at Lincoln Elementary or the district office' shrinks the sweep, which makes it faster and its results easier to check.
- 4
Ask it to note the gaps
The most valuable output is often what's missing: 'list which expected documents never showed up' turns a search into a to-do list.
- 5
Verify each hit at the source
Ask Muse to quote sender, date, and the key line from each match, then open the originals. Summarized search results are a map, not the destination.

Goal: Find every email I need for [PURPOSE, e.g. this year's tax filing] and line them up in one place. Context: My mailbox goes back [RANGE, e.g. two years] and the documents are scattered across [FOLDERS OR ACCOUNTS]. Requirements: - Look for [TYPES, e.g. receipts, donation confirmations, invoices] dated [DATE RANGE]. - For each match record sender, date, amount, and any reference number. - Skip marketing mail even when it mentions [TOPIC] — only real records count. Actions: - Search the mailbox category by category, including inside attachments where you can read them. - Note gaps: which expected items have no matching email at all. Approval: This sweep is read-only — do not move, tag, archive, or delete anything you find, and check with me before doing anything to any message. Output: A table of matches sorted by date, a short list of what looks missing, and totals for [FIGURE, e.g. deductible amounts] as a starting point — not a final answer.
Example
A parent assembling every school form and medical reminder before the first day of term.
Search my inbox for everything school- and health-related from the past six weeks: permission slips, the bus-route confirmation, the pediatrician's reminder about vaccination records, and any email from Lincoln Elementary or the district. For each match give me the sender, the date, what's being asked of us, and any deadline. Check inside attachments where you can — most forms arrive as PDFs. Then tell me what's still outstanding, like forms I apparently never submitted or confirmations I never received. This is read-only: don't move, tag, or delete anything, just show me what you found.
What Information Should You Provide?
What the email is about, in plain terms
Intent-based description lets Muse catch varied wording; a single guessed keyword is how important mail stays lost.
Approximate date range
Bounds keep the sweep fast and the result list short enough to actually review.
Likely senders
Organizations, clinics, or stores name themselves inconsistently — listing the ones you know helps, and Muse can infer related domains.
Whether attachments count
Receipts, forms, and tickets usually live inside PDFs; including them makes the search slower but far more complete.
The account(s) to search
Muse finds nothing in an account you never connected — deciding scope up front avoids false 'it's not there' conclusions.
Approval and Safety
For this task, it is smart to make Muse check with you before it takes certain actions. Decide your rules up front and include them in the prompt.
Any action on a found message — Searching and filing are different jobs; keep the sweep read-only and decide the fate of each message yourself.
Forwarding results to anyone — Found mail often contains personal or financial details — the summary alone may reveal more than you intend to share.
Acting on a match you haven't opened — Before paying, disputing, or submitting based on a search result, open the original message and confirm it says what the summary claims.
Tips for Better Results
- Chunk long ranges: a sweep of 'all of 2025' is more reliable as four quarterly passes, especially while the product is new.
- Pair searches with gap-hunting — 'what's missing' is frequently more useful than what turned up.
- For tax or legal use, ask for reference numbers and exact quotes so you can jump straight to the source message.
- If the first pass comes back empty, loosen the sender constraint before loosening the date range; wording varies more than timing.
- Keep a running instruction for recurring hunts (monthly receipts, school mail) so the next search starts from a tested prompt.
Find Important Emails FAQ
Can Muse search my email?
Yes, within the account you connect and at the access level you choose — read-only is enough for search. Meta says people pick which apps Muse connects to and how much access each gets, so a search-only setup never needs send permissions.
Can Muse find receipts in my email for taxes?
It can sweep the connected account for purchase records, extract amounts and dates, and flag gaps — including inside attachments where it can read them. Given the product is days old, treat the output as preparation for your accountant rather than a finished reckoning, and spot-check the originals.
Does Muse read my whole mailbox?
It reads what's in the connected account and the scope you give it. If you'd rather it not wander, bound the request by folder, sender, and date range — the search stays tighter and faster. Nothing outside the connected account is visible to it.
Can Muse find emails with attachments?
Ask it to include attachment contents and it can look inside files like PDFs as part of the sweep. That's slower than a subject-line scan, so it's worth bounding by date and sender — and worth verifying, since attachment parsing is exactly the kind of step launch-week agents sometimes fumble.
Is searching my email with Muse private?
Meta says Muse runs in a secure VM that houses your data, and that conversations and VM data aren't shared with Meta's ad systems. Retention specifics haven't been published; you can tell Muse to forget specific things, and check the Muse app's privacy settings — press reporting (CNBC) describes AI-training use as opt-out, so review it yourself.
