How to Connect Multiple Gmail Accounts to Claude
Yes, you can use several Gmail accounts with Claude, but not through Claude’s own Google connector. That connector authorizes one Google identity at a time. Connect every account to Carly instead, add Carly to Claude once, and a single conversation can search or act across the right inbox. The same Carly account holds your Outlook mailboxes and every calendar on both sides, so you set this up once for all of it.
1. Add your Gmail accounts to Carly
- Sign in at carlyassistant.com.
- Open carlyassistant.com/integrations.
- Find Gmail, click Connect, and authorize the account.
- Click Connect again for the next one, and keep going for as many accounts as you want.
If a Google Workspace account requires administrator review, ask the Workspace administrator to approve the connection, then finish authorization.
Nothing is merged or forwarded. Each mailbox keeps its own credentials, and Carly keeps them addressable by name.
Carly connects to thousands of apps, so while you are on that page you can add your calendars, files, CRM, and anything else you want Claude to reach through the same connector.
2. Add Carly to Claude
- Open Customize → Connectors in Claude.
- Choose Add custom connector.
- Paste
https://carlyassistant.com/mcp/. - Continue to authorization.
- Sign in to the Carly account holding the Gmail connections.
- Enable the connector for your conversations.
If the option is missing on a Team or Enterprise plan, the workspace administrator may need to allow custom connectors first.
What changes once every account is connected
One Claude conversation can:
- search personal and work Gmail together;
- pull threads from several company accounts into one answer;
- build a morning briefing grouped by inbox;
- draft or send from the exact Gmail address you name;
- label, move, or archive in the correct account;
- read several calendars while writing to only one.
One connector, one account. That is still the shape in Claude and Gemini. The Gmail or Google Workspace connection authorizes a single identity, so a second account overwrites the first instead of sitting beside it. Anyone running a personal address and a work address does the disconnect and reconnect dance to move between them. Connect all of them to Carly instead and the dance stops.

The connector is the smallest thing Carly does
The account routing is table stakes for Carly. It is a full AI executive assistant: morning triage cleared, replies drafted in the right account, quiet threads chased, meetings booked around every calendar, all without a conversation open. Turn on a pre-built recipe like a daily brief across every inbox and it runs from tomorrow morning.
Quick fixes when an account does not appear
| Problem | Fix |

| Workspace blocks authorization | Ask the Workspace administrator to approve Carly |
| Custom connector option is missing | Ask the Claude workspace admin to allow custom connectors |
| Carly is connected but never used | Enable the connector for the current conversation |
| Claude searches the wrong inbox | Use the full address and require source attribution |
Frequently asked questions
Can Claude connect to two Gmail accounts natively?
Claude’s Google Workspace connector authorizes one Google identity per connection, so a second account replaces the first. Connecting each account to Carly and adding Carly to Claude is the direct way to keep several available at once.
Can I mix personal Gmail and Google Workspace?
Yes. Connect each Google identity to Carly separately and give every address a clear Personal or Work role. Carly treats them as independent accounts regardless of which is a Workspace domain.
Does this merge everything into one inbox?
No. The accounts stay separate and keep their own credentials. Claude can search across them, and Carly routes each draft, label, send, or move to the address you specify.
Should the recurring inbox work run through Claude?
Claude only acts while the conversation is open. Give the recurring work to Carly and it runs unattended in the same connected accounts.
Does this work in Claude Cowork too?
Yes, and the setup is the same. Connecting multiple Gmail accounts to Claude Cowork covers the Cowork specifics.

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."
