On October 8, 2026, Google Cloud announced coworker agents: Gemini agents with their own Workspace account and an @agents.company.com email address. What Google said, what it left open about signatures, and how to get a coworker agent's email signature ready before it sends. On October 8, 2026, Google Cloud announced coworker agents: Gemini agents that a team creates for a role, each with its own Workspace account, calendar, Drive and an email address on an `@agents.company.com` domain. Google has not said what a coworker agent's email will end with. In Gmail, a saved signature is added by the compose window, and an agent writing through its own account may never open one. Decide now how the agent will sign: its name, its role, that it is an AI, and the person or team it works for. ## Google gives each coworker agent an account, an address and an audit trail Thomas Kurian, CEO of Google Cloud, introduced the Gemini agent at Gemini at Work 2026, in a [keynote post](https://cloud.google.com/blog/products/ai-machine-learning/welcome-to-gemini-at-work-2026) dated October 8, 2026. On coworker agents, it says: - **Its own address.** Coworker agents have "dedicated identities" with their own `@agents.company.com` email addresses, "their own persistent storage, and only have access to the context that you or your team members provide." - **Its own Workspace account.** "You simply describe the role you need, and Gemini creates it. The agent receives its own Workspace account, including an email address, calendar, Drive, and presence in your company directory." - **Its own name on its work.** "A coworker agent acts under its own identity rather than yours, and it sees only what you share with it." In Google's example, an events coordinator agent drafts a document for a marketing team and appears "under its own name in version history." - **An audit trail under the agent's name.** "Every agent gets its own identity, cryptographically attested and governed like an employee", and "every action Gemini takes is written to an audit trail and attributed to the agent rather than to a person." The same post describes the personal side of the agent, working as you. Asked to set up a meeting, it "starts an email thread to coordinate a time that works, even with external participants." That is Gemini working as "your personal agent", separate from a coworker agent. The post gives no date, plan or price for coworker agents. The only availability it states is for the industry versions, "now in preview for Financial Services and Legal". ## Why a new address starts with no signature A Gmail signature is a setting of one account and one address. Google's Gmail API reference describes it as "An optional HTML signature that is included in messages composed with this alias in the Gmail web UI," and adds: "This signature is added to new emails only." A coworker agent's account is a new account, so it starts with no signature saved. And an agent that sends through Google's systems sits outside the Gmail web UI that the API reference names. Until Google says otherwise, plan for email from an `@agents` address that ends where the agent's text ends. That matters more for an agent than for a person. The address `@agents.company.com` hints that an agent wrote the email. The agent's role, the company it works for and a person to reach when the agent gets something wrong belong in the signature, where readers look for them. The EU's rules on AI that interacts with people also expect an agent to say that it is an AI and whom it acts for; our [AI email disclosure page](https://signatoro.com/email-signature-compliance/ai-email-disclosure) covers what that asks of an email. ## How to get a coworker agent's signature ready Google has given no date for coworker agents, so this is preparation. Each step works the same for any agent with its own mailbox. 1. **Name the agent and its role.** Use the role you will describe to Gemini, such as "Events coordinator", and say it is an AI agent: "Events coordinator (AI agent), Northwind Marketing". 2. **Name a person or team to reach.** Add the email of the person who owns the agent's work, or of the team inbox. A reader with a problem writes to a person. 3. **Add a short AI line.** For example: "I'm an AI agent working for the Northwind marketing team." Put the same sentence at the top of emails to people outside the company. 4. **Keep the company brand.** Use the logo, colors and company details your people use, so the agent's email looks like it comes from the company it works for. 5. **Leave out what belongs to people.** No personal mobile number, no photo of an employee. 6. **Check the first email it sends.** When your company gets access, have the agent email someone on your team, and read the end of the message. If it ends without a signature, give the agent one before it writes to anyone outside. If you can save a signature in the agent's Gmail settings, save it there too, and let the first sent email show whether it is used. ## Where Signatoro fits Signatoro is the agentic email signature platform: save your signature once, and your people and every AI agent you connect use the same one. On the Company plan, the owner sets up company AI agents that sign with the company brand, the agent's name and role, and an AI line, with no personal phone or photo. The owner can require one AI line for every agent. Agents use no seat. An agent fetches its signature at send time, through Signatoro's MCP server or API, so the next email carries any change made on Signatoro. Google's post says the Gemini agent "can also connect and work securely with any Model Context Protocol (MCP) server inside or outside your company network." We have not tested a coworker agent with Signatoro, since we have no access to the preview.

Yes, by Google's October 8, 2026 announcement: each gets its own Workspace account with an email address on an `@agents.company.com` domain, a calendar, Drive and a listing in the company directory. ### When can my company use coworker agents? Google's announcement gives no date, plan or price for them. It says the Financial Services and Legal versions of the Gemini agent are "now in preview". ### Will a coworker agent's email include a signature? Google has not said. A Gmail signature is saved per account and is added in Gmail's own compose window, so a new agent account starts without one. Give the agent a signature and check its first email. ### Does a coworker agent send email as me? No. Google says a coworker agent "acts under its own identity rather than yours". Gemini working as "your personal agent" is a different setup, and Google's post does not say which address its email threads come from. ### What should a coworker agent's signature say? Its name and role, that it is an AI agent, the company it works for, and a person or team to reach. Keep the company's logo and details, and leave out personal phone numbers and photos. ## Sources Read on November 2, 2026: - [Gemini at Work 2026: Introducing Gemini agent (Google Cloud Blog, October 8, 2026)](https://cloud.google.com/blog/products/ai-machine-learning/welcome-to-gemini-at-work-2026) - [REST Resource: users.settings.sendAs (Gmail API)](https://developers.google.com/workspace/gmail/api/reference/rest/v1/users.settings.sendAs)
