How to Connect Multiple Gmail Accounts to Grok
Grok has a capable Gmail connector, but xAI does not document a way to connect two Gmail accounts at once. The built-in Google Workspace connection can search mail, handle drafts, send, reply, forward, label, and trash. It can even trigger an automation when a new email matches a sender, recipient, or subject. That still leaves the personal-plus-work problem unanswered. Carly keeps each Gmail identity as a separate connection and exposes them to Grok through one custom connector.
Grok’s Gmail connection is unusually capable
xAI launched Grok Connectors in May 2026 on the web, iOS, and Android. Google Workspace is one integration covering Gmail, Drive, Docs, Sheets, and Calendar. Unlike the read-only connectors many assistants started with, xAI says Grok can read and write emails, documents, spreadsheets, and events.
The Gmail and Google Calendar documentation is specific about the permissions. Search and reading use gmail.readonly; modifying drafts and labels adds gmail.modify; sending adds gmail.send; and label management adds gmail.labels. Those additional scopes are requested only when the corresponding tools are enabled.
Connectors are available to all Grok users. In Business and Enterprise workspaces, a team administrator must provision the connector in the cloud console before members can use it.
The second-account behavior is not documented
xAI’s setup guide describes authorizing a Google account, and its Outlook documentation says Grok can access only the signed-in user’s mailbox. None of xAI’s connector pages states whether selecting Gmail a second time adds another identity, replaces the first, or produces an error.
That wording matters. Several third-party pages claim you can simply repeat the authorization for another Gmail address, but xAI does not make that promise. Until the product documents or exposes named connections, the safe answer is: one signed-in Gmail identity is documented; simultaneous multi-account support is not.
Email triggers do not solve account routing
Grok’s Automations can run on a schedule, and SuperGrok adds a genuine email trigger. An automation fires when an incoming message matches a sender, recipient, or subject filter, with that email supplied as context.
Since July 2026 Grok can start work on its own two ways: a schedule, or an incoming email that matches your filters. Email is the only event it watches. The connectors it has to Salesforce, Teams, SharePoint, and the rest never fire anything — they wait to be asked inside a conversation.
xAI does not say which inbox is watched if several mail connectors exist. An email trigger therefore is not evidence that Grok can hold several Gmail accounts or reliably choose among them.
1. Give each Gmail account a role
Use names that make sense inside an instruction. For example, all fictional:
| Address | Role |
|---|---|
fictional.ava.chen@gmail.com | Personal |
fictional.ava.chen@adobe.com | Main Company |
fictional.ava.chen@nike.com | Client |
The role is convenient for searching. The full address is safer for anything that sends or changes data.
2. Connect every Gmail account to Carly
- Sign in at carlyassistant.com.
- Open carlyassistant.com/integrations.
- Find Gmail and click Connect.
- Choose the first Google account and approve the permissions.
- Return to the integrations page and select Gmail → Connect again.
- Choose Use another account if Google preselects the previous login.
- Confirm the full address after every authorization.
The accounts are not forwarded or merged. Each one keeps its own credentials and permissions, which is what makes a named-account instruction reliable.
3. Add Carly to Grok as a custom connector
Grok has a real paste-a-URL connector flow:
- Open grok.com/connectors.
- Choose New Connector.
- Select Custom.
- Enter
https://carlyassistant.com/mcp/as the MCP server URL. - Complete authorization.
xAI’s custom connector instructions require a server reachable over the public internet; a local server needs a tunnel. Carly is already remote, so no local setup is required.
4. Test each inbox before enabling writes
Start with one read-only request per address:
In
fictional.ava.chen@adobe.com, list the sender and subject of the five newest unread messages. Do not change anything.
In
fictional.ava.chen@nike.com, find the newest thread containing “launch plan.” State the source address and do not draft.
Then test a cross-account search:
Search the Adobe and Nike example accounts for “renewal” from the last 30 days. Include the full source address in every row.
5. Reuse this account-routing prompt
Treat
fictional.ava.chen@gmail.comas Personal,fictional.ava.chen@adobe.comas Main Company, andfictional.ava.chen@nike.comas Client. Always state the target address before changing anything. Wait for approval before sends, replies, labels, trash, or calendar changes.
Then repeat the address in each action:
Draft a reply from
fictional.ava.chen@adobe.com. Do not send yet.
Apply the Follow Up label in
fictional.ava.chen@nike.comonly.
Grok’s Gmail connector next to Carly
| Need | Grok Google Workspace connector | Carly |
|---|---|---|
| Read and search one Gmail account | Yes | Yes |
| Draft, send, reply, and label | Yes, when write tools are enabled | Yes, with the account’s permissions |
| Keep several Gmail identities connected | Not documented | Yes |
| Search across two inboxes in one request | Not documented | Yes |
| Trigger from an incoming email | SuperGrok | Yes |
| Add by remote MCP URL | Yes | Grok connects to Carly by URL |
Carly offers free Zapier-style workflows; AI agents start at $35/month.
Quick fixes
| Problem | Fix |
|---|---|
| Gmail appears read-only | Enable the Gmail write or send tools so Grok can request the additional scopes |
| Business connector is missing | Ask the Grok team administrator to provision it in the cloud console |
| Google authorized the wrong address in Carly | Reconnect and choose Use another account |
| Custom connector cannot be reached | Confirm the URL is public and uses the supported remote transport |
| Results come from the wrong inbox | Put the full address in the prompt and require source attribution |
| Email automation watches an unclear mailbox | Test with a harmless filtered message before relying on the trigger |
Frequently asked questions
Can Grok connect two Gmail accounts?
xAI does not document a multi-account setup or describe what happens when a second Gmail identity is authorized. Connecting each account to Carly gives Grok one account-aware route to all of them.
Can Grok send Gmail messages?
Yes. The connector documents draft, send, reply, forward, label, trash, and delete tools. Write and send scopes must be enabled before those actions are available.
Can Grok react to a new email automatically?
Yes, on SuperGrok. Email-triggered automations match incoming messages by sender, recipient, or subject. xAI does not document multi-inbox routing for those triggers.
Does Grok support custom MCP connectors?
Yes. Choose New Connector, select Custom, paste the public MCP server URL, and authenticate. This is separate from the remote MCP tooling in the xAI developer API.

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."
