Can Meta Muse Send Emails From Gmail and Outlook?
Yes. Muse drafts and sends from the Gmail and Outlook accounts you connect, and its Gmail connector now holds more than one account. Out of the box, sending is set to ask: Muse writes the email and waits for you to approve it.
With Carly, Muse sends from every address you own, on your rules. Personal and work, Gmail and Outlook, shared mailboxes like billing@ included, with attachments. Routine replies can go out on their own, every email is logged in your CRM, and the files that come back get saved where they belong.
Set it up in Muse
- Connect every mailbox you send from at carlyassistant.com/integrations, shared ones included.
- Paste the prompt below into Muse. It adds Carly as a custom connector.
- When Muse asks for a key, open your Carly account page, click API keys, name the key “Muse”, leave every permission ticked and click Generate key. Paste it into Muse’s secure credential prompt, not the chat.
- Send from the right address:
Reply to the invoice question from my billing@ address and attach last month’s statement.
Carly setup prompt for Muse
Paste this into Muse. It adds Carly and walks you through connecting every address you send from.
Help me set up Carly. I'll add it to you myself: tell me exactly what to click for the app you are, one step at a time, and wait for me to confirm before moving on. If you can do the setup yourself (Claude Code, Codex, Muse, Grok Bot), go ahead, and ask me for any key in your secure credential prompt, never in the chat. Once it's added, walk me through connecting my accounts, check it worked by listing every mailbox and calendar you can see through Carly, and ask what I want to hand off first. The steps are below.
# Connect Carly to an AI app
> Carly connects to thousands of apps, from Gmail, Outlook and calendars to Slack, HubSpot and QuickBooks, and keeps working after a chat is closed: answering email, booking meetings, following up and running workflows the moment something happens.
MCP server: https://carlyassistant.com/mcp/ (streamable HTTP, OAuth)
## Setup
1. Add the Carly plugin (some apps call it a connector):
- ChatGPT: open https://chatgpt.com/plugins/plugin_asdk_app_6a67a26316b88191860222f918d4ec54 (or open Plugins and search "Carly"), add it, and sign in.
- Claude (claude.ai, Claude Desktop, or Cowork): open https://claude.ai/directory/carly, click Connect, and sign in.
- Claude Code: `claude mcp add --transport http --scope user carly https://carlyassistant.com/mcp/`, then /mcp, pick carly, and authenticate.
- Codex: `codex mcp add carly --url https://carlyassistant.com/mcp/`, then `codex mcp login carly`.
- Cursor: add {"mcpServers": {"carly": {"url": "https://carlyassistant.com/mcp"}}} to ~/.cursor/mcp.json, then sign in to carly from Customize.
- Muse: a custom connector to https://carlyassistant.com/mcp/ with a Carly API key as its bearer token. The key comes from carlyassistant.com/account (API key under Carly) and goes in Muse's connector settings, not in a chat message.
- Grok: grok.com/connectors > New Connector > Custom, paste https://carlyassistant.com/mcp/, and sign in.
- Grok Bot: a custom remote MCP server named carly at https://carlyassistant.com/mcp. Approve it and sign in.
- Perplexity: Plugins in the sidebar (or Customize > Connectors), then Add custom > Connector > Add MCP connector. Choose Remote, name it Carly, paste https://carlyassistant.com/mcp/, pick OAuth, check the box and click Add, then click the Carly card to sign in.
- Anything else: a remote MCP server (streamable HTTP) named carly at https://carlyassistant.com/mcp/. It signs in with OAuth.
Sign in with a Carly account, or create one at carlyassistant.com.
2. Once it's added, Carly's tools show up in the chat. If they don't, turn Carly on for the chat or start a new chat.
3. Connect accounts at https://carlyassistant.com/integrations. Under Accounts, click Connect Google or Connect Microsoft, pick the account and grant everything it asks for. If the page shows an email field instead, type the address, click Add Email, click Connect Google or Connect Microsoft on the new address, then Connect with Google or Connect with Microsoft. For an address that is already connected, open Manage access and click Connect next to anything missing. Repeat for every account, then connect any other apps.
4. To check it worked, ask Carly to list every connected mailbox and calendar.
5. Something to hand off first: "Check all my inboxes for anything that needs a reply today."
## Business calls and texts
Business SMS, business phone calls, voicemail and a team's voice and text agents are a separate connector, Carly Teams, at https://carlyassistant.com/team/mcp. It needs membership of a Carly organization and its own connection. Its setup is https://carlyassistant.com/team/mcp.txt.How sending works in Muse
Every permission on Muse’s Gmail connector can be set to Allow or Ask. In the settings we checked, drafting was set to allow, and sending and unsubscribing were set to ask. Meta’s launch post describes the same split: “people choose what Muse can do, whether it reads their mail or can also send on their behalf,” and Muse “checks with the person before sensitive actions like sending an email.”
So a send in Muse goes: you ask, Muse drafts from the right connected account, an approval card appears, you tap, it goes. Inc reported that Muse “could already schedule meetings, update your calendar, send emails” from launch.
Where sending stops
Every send is a judgment call. Muse decides what to write each time. Its own connect screen warns that Muse “may take unexpected actions. Monitor it carefully.” That’s fine for a one-off email. It’s a lot to monitor for the twentieth routine reply of the day.
Approval is the default. Leave sending on ask and routine mail waits for you. Switch it to allow and you’re trusting an improvising agent with your outbox.
Gmail and Outlook are separate connectors. Each has its own accounts and permissions, so one sending rule doesn’t span both.
| Muse on its own | Muse with Carly | |
|---|---|---|
| Addresses it can send from | Its connected Gmail and Outlook accounts | Every address you connect, shared mailboxes included |
| Routine replies | Muse writes each one, asks first | Your template, sent by your rule |
| Every sent email logged in your CRM | When you ask | Automatically |
| Follow-ups when nobody replies | When you ask | Drafted every weekday morning |
Sending on rules with Carly
Carly sends the same way every time, from the right address, by the rules you write. Ask Muse to set any of these up once Carly is connected:
- Reply to routine mail. “Send our rate sheet to anyone who asks for pricing” goes out from the address they wrote to, attachment included.
- First reply to new leads. When a lead emails for the first time, Carly sends a tailored reply from your own mailbox.
- Forward matching mail. Receipts to your bookkeeper, applications to the hiring manager, with their attachments.
- File what comes back. Signed contracts and invoices land in the right Dropbox or Drive folder automatically.
- Update your CRM. Every email to a client is logged on that person in Carly’s CRM, HubSpot or Salesforce.
- Chase quiet threads. Carly drafts the follow-up when nobody has answered for as long as you choose.
Carly also has its own email address, so clients can write to it directly and it answers for you. Carly connects to thousands of apps. Free Zapier-style workflows; AI agents from $35/month. Get started.
Frequently asked questions
Can Meta Muse send emails without asking me?
Sending is set to ask by default, and Meta says Muse checks with you before sensitive actions like sending an email. With Carly, you decide which replies go out on their own and which wait in Drafts.
Can Carly send attachments through Muse?
Yes. Ask Muse and Carly sends the file from whichever Gmail or Outlook account you choose, and automatic replies can carry attachments too, like a rate sheet or a contract.
Can Muse send from my work email?
Yes, if that account is connected. A client’s mailbox or a shared address like billing@ goes in through Carly. See Can Meta Muse connect to multiple email accounts?
Can Muse send email from its own address?
Meta said at Connect in September that Muse will get its own email address. Until that reaches your account, you can give Muse a real inbox of its own on CarlyEmail.
Can Muse send from Outlook?
Yes, through its Outlook Mail connector. See Can Meta Muse access Outlook?

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."
