Can Meta Muse Connect to Multiple Email Accounts?
Only one of each. Meta Muse’s Gmail connector holds one Google account and its Outlook connector holds one Microsoft account, with no option to add a second to either. So Muse can see one Gmail and one Outlook, and your personal and work inboxes on the same provider can’t sit in Muse together.
But you can use Muse across every inbox you own. Put the accounts in Carly, add Carly to Muse once as a custom connector, and one chat reaches all of them.
Do this instead
- Connect every inbox at carlyassistant.com/integrations: Gmail and Outlook, personal and work, as many as you like.
- On the same page, open Advanced → API Keys → Create a new key, name it “Muse”, click Select all above the scopes, then Generate key and copy it.
- In a Muse chat, send: Build a custom connector to https://carlyassistant.com/mcp/ using an API key as a bearer token. Paste the key when Muse asks for it in its secure credential prompt, not into the chat.
- Ask across all of your inboxes at once:
Check all my inboxes for anything from the landlord, the accountant or the school and tell me what needs a reply this week.
That is the whole setup. Get started at carlyassistant.com.
What Muse’s own connectors hold
| Muse on its own | Carly connector in Muse | |
|---|---|---|
| Gmail accounts at once | One | All of them |
| Outlook accounts at once | One | All of them |
| Gmail and Outlook together | One of each | All of them |
Shared mailboxes like billing@ | Not documented | Yes, as their own mailbox |
| Work starts when mail arrives | No | Yes, in every inbox |
Muse is good at errands, and since Muse for Small Business it reaches work apps like Slack, QuickBooks and Shopify. Mail is where it stays narrow: a second Gmail or a second Outlook gets answered as if that inbox didn’t exist.
What Muse can do once Carly is connected
Muse handles errands well. Add Carly and it handles your mail too:
- Every Gmail and Outlook account in one chat, not one of each.
- Shared mailboxes like
billing@, read and answered as themselves. - Rules that stick. Carly labels and sorts every email by the list you write.
- Bookings checked against every calendar you own.
- A text to your phone when a client is waiting, plus a business line Carly can answer.
- Everything else you run. Carly connects to thousands of apps, so a request in Muse can reach QuickBooks, Shopify or your CRM.
What you can automate across all of them
Carly works every inbox you connect, with no Muse chat open:
- Text me when an urgent email arrives. A real person waiting on you, a deadline or money sends a text to your phone.
- Label and sort every email. Carly applies your Gmail labels and Outlook categories by your rules, the same way every time. Nothing is deleted.
- Draft replies to the emails that need you, in your voice, saved to Drafts.
- Book meetings across every calendar before offering a time.
- Chase threads that went quiet and stop when someone answers.
Carly connects to thousands of apps, so the far end of any automation can be a tool you already pay for. Browse more at carlyassistant.com/workflows.

Frequently asked questions
Can I connect two Gmail accounts to Muse?
Not with Muse’s own Gmail connector, which holds one Google account. See Can Meta Muse connect to multiple Gmail accounts?
Can I connect two Outlook accounts to Muse?
Not with Muse’s own Outlook connector, which holds one Microsoft account. See Can Meta Muse connect to multiple Outlook accounts?
Can Muse use Gmail and Outlook together?
Yes, one of each through its own connectors. Through Carly, every Gmail and Outlook account sits behind one connector and one request covers all of them.
Is a custom connector safe?
Meta does not review custom connectors. Carly signs in to each account through Google’s or Microsoft’s own sign-in, never sees your password, and does not train on customer data. You can disconnect any account from Carly at any time.
How many inboxes can Carly hold?
As many as you connect at carlyassistant.com/integrations, personal and work, on both providers.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
