How to Connect Multiple Gmail Accounts to Claude Cowork
Yes—you can connect multiple Gmail accounts to Claude Cowork with Carly. Add every personal Gmail and Google Workspace account to Carly once, connect Carly to Claude, and Cowork can search or act across the right inbox without making you disconnect one Google account and sign in to another. 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 Google Workspace shows an administrator-review message, ask the Workspace administrator to approve the connection, then repeat the authorization.
There is no forwarding, POP import, or mailbox merge. Each Gmail account remains its own connection, so Carly can route work to the right one.
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 Cowork to reach through the same connector.
2. Connect Carly to Claude Cowork
In Claude:
- Open Customize in the sidebar.
- Select Connectors.
- Click +, then Add custom connector.
- Paste
https://carlyassistant.com/mcp/. - Click Add and authorize your Carly account.
- In the Cowork task, open + → Connectors and enable Carly.
Anthropic documents this path in its remote MCP connector guide. On Team and Enterprise, an Owner may need to add the connector to the organization before members can connect it.
What the finished setup gives you
With one Carly connector in Cowork, you can:
- search several Gmail accounts in one task;
- build one briefing from personal and work inboxes;
- compare threads across two company accounts;
- draft or send from the exact address you choose;
- organize the correct inbox with labels and moves;
- check several calendars while creating an event on only one.
The accounts stay separate underneath. Carly supplies the multi-account routing, and Claude remains the workspace where you run the task.
Why Claude’s native Gmail connector does not solve this
Anthropic says Claude can access Gmail, Calendar, and Drive data for the Google account connected to Claude. That works well for one identity. It does not create one Cowork task with several independent Google logins available at the same time.
Native Gmail versus Carly in Cowork
| Need | Claude’s native Gmail connector | Carly connector |
|---|---|---|
| Search one Google account | Yes | Yes |
| Use multiple independent Gmail accounts | Not in one native connection | Yes |
| Compare several inboxes in one task | No | Yes |
| Send from a named connected Gmail account | Native Gmail creates drafts but does not send | Yes, with the connected account’s permissions |
| Run recurring multi-account workflows | No | Yes |
Anthropic notes that the native Gmail connector can send, reply to and forward email, asking your approval by default. Carly can supply the send and workflow layer as well as the multi-account connection. Carly offers free Zapier-style workflows; AI agents start at $35/month.
The connector is the smallest thing Carly does
Carly does not stop at handing Cowork your inboxes. It is a full AI executive assistant that works them: triage done before you sit down, drafts parked in the right account, follow-ups chased, meetings booked across every calendar, with no task open. Pre-built recipes like a daily brief across every inbox take a few clicks to turn on.
Quick fixes when an account does not appear
| Problem | Fix |
|---|---|
| Google connected the same address twice | Remove the duplicate and reconnect with Use another account |
| Workspace blocks the connection | Ask the Workspace administrator to approve Carly |
| Carly is installed but unavailable in Cowork | Open + → Connectors and enable it for the task |
| Cowork searches the wrong inbox | Use the full address and request a source-account column |
| Claude cannot add Carly | Ask the Claude Owner to enable the custom connector |
Frequently asked questions
Can Claude Cowork connect two Gmail accounts natively?
Claude’s Google connector is tied to the Google identity you authenticate. Carly is the straightforward way to make several separately connected Gmail identities available inside one Cowork task.
Can I connect personal Gmail and Google Workspace together?
Yes. Connect each account separately to Carly, add Carly to Claude.
Should the recurring inbox work run inside Cowork?
Cowork only acts while a task is open. Give the recurring work to Carly and it runs unattended in the same connected accounts.
Does Carly merge the inboxes?
No. The Gmail accounts remain separate. Cowork searches across all of them at once, and every draft, label, send, or move lands in the correct account.

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."
