Meta Muse With Multiple Accounts (2026)
Meta Muse connects to your email and calendar through built-in connectors for Gmail, Google Calendar, Outlook Mail, and Outlook Calendar. Each of those connectors holds one account.
That covers someone with one Gmail. It does not cover the person with a personal Gmail, a business Gmail, and a client’s Outlook, which is most people who run their own business. Add Carly to Muse as a custom connector and Muse works across all of them at once.
What Muse sees natively
| Your setup | What Muse’s own connectors reach |
|---|---|
| Personal Gmail + business Gmail | One of the two |
| Two Outlook accounts | One of the two |
| One Gmail + one Outlook | Both, one of each |
| Calendars on two different Google accounts | One account’s calendars |
A shared mailbox like billing@ | Not documented |
The one mixed pair that works natively is one Gmail plus one Outlook, because they are different connectors. A second account on the same provider is where it stops.
The fix: one Carly connector for every account
Carly holds as many Gmail and Outlook accounts as you connect, plus every calendar on both sides. Muse reaches all of them through a single custom connector.
- Sign in at carlyassistant.com and open carlyassistant.com/integrations.
- Find Gmail or Outlook, click Connect, and repeat for every account you want.
- At the bottom of 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 this message, then paste the key when Muse asks for it in its secure credential prompt:
Build a custom connector to https://carlyassistant.com/mcp/ using an API key as a bearer token.
Then ask across everything at once:
Check all my inboxes and calendars and tell me what I need to handle before my 2pm.
Carly connects to thousands of apps, so the same connector can bring your CRM, files, and task list into Muse too.

Where Carly goes past the connector
Muse handles errands well, and since Muse for Small Business it reaches apps like Slack, QuickBooks and Shopify too. Carly is built for the accounts that pay you.
It watches every connected mailbox and calendar on its own. When a client emails your business address, a Carly workflow can draft the reply from that account, book the call around every calendar you have, and log it in your CRM before you open Muse. Booking pages and group scheduling come with it, across unlimited connected calendars.
Carly offers free Zapier-style workflows; AI agents start at $35/month.
Frequently asked questions
Can Meta Muse connect two Gmail accounts?
Not through its own Gmail connector, which holds one Google account. Carly holds both and reaches Muse through one custom connector. See can Meta Muse connect to multiple Gmail accounts?
Can I use Muse for work and personal email at the same time?
Natively, only if one is Gmail and the other is Outlook. With Carly connected, any mix works, including two Gmails.
Is a custom connector safe?
Meta does not review custom connectors, so it is worth knowing what you are connecting. 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.
Does Muse keep the accounts separate?
Yes. Nothing is merged or forwarded. Each account stays its own connection in Carly, and every draft, send, or calendar change lands in the right one.

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."
