As of October 7, 2026, a Grok Bot can send email from the Gmail or Outlook account you connect to it, and since version 0.64.0 of September 30, 2026, you can let a Bot send without showing you a draft first. The email goes out from your address, under your name. Inboxes that belong to a Bot come from a third-party plugin, AgentMail.
That difference decides what your recipients see at the bottom of the email. Below is what xAI shipped, where Bot-owned addresses come from, and how to make sure every email a Bot sends ends with your real signature.
xAI shipped email sending in steps, ending with no draft at all
xAI (which now signs its posts SpaceXAI) launched Grok Bot in beta on August 11, 2026, for SuperGrok and Cursor subscribers. A Bot is an always-on agent with a cloud computer of its own. In xAI's words: "Bots have their own computer. They sign into the tools you already use and work across apps, inboxes, and more."
Email arrives through plugins you add from the Grok Bot Marketplace, Gmail among them. xAI's docs say "Installed connectors are account-wide", so every Bot on your account can use the mailbox you connect. The Grok Bot changelog then added sending, one step at a time:
- v0.60.0, September 26, 2026. "Editable email drafts work with Outlook: review a Bot's new email in chat, then choose Send email to send it from your Outlook account."
- September 28, 2026. "Emails a Bot sends through Gmail go to the recipients it names, not to a saved draft's original recipients."
- v0.64.0, September 30, 2026. "Email and Slack draft cards offer Disable drafts for this Bot, so that Bot sends messages directly; ask the Bot to turn drafts back on."
The last entry is the one that matters most. With drafts on, you read each email in a card and click "Send email". With drafts off, the Bot sends on its own, from your account.
These sit beside Grok's earlier email features: Connectors (May 6, 2026), where the Outlook connector "can draft and send emails"; Automations (July 16, 2026), which run when a matching email arrives; and the Grok for Outlook add-in (July 21, 2026), which drafts replies inside Outlook.
Do Grok Bots get their own email address?
As of October 7, 2026, no xAI announcement gives a Bot an address of its own. Reports that xAI is "adding mailboxes for Grok bots" are not supported by xAI's news page, the Grok Bot docs or the changelog through v0.66.0 (October 2, 2026). Two things lie behind those reports:
- AgentMail's plugin. AgentMail, a separate company, lists a plugin in the Grok Bot plugin browser that gives each Bot "a real email address at
yourworkspace.agentmail.to". AgentMail's own FAQ says it "is an independent company; the marketplace listing is the extent of the xAI relationship." Its setup post, dated August 22, 2026, explains the pitch: "Grok Bot ships with a Gmail plugin, but that plugin points at your inbox." - Code in the Windows app. On October 7, 2026, RuntimeWire reported that a static inspection of the Grok Bot 0.68.1 Windows package found a gated workflow for creating
@mail.grokbot.comaddresses, with its feature switches off by default. RuntimeWire says it did not run the app or claim an address, and that the code does not show each Bot getting its own mailbox. xAI has not announced the feature.
So today a Grok Bot sends email in one of two ways: as you, from the Gmail or Outlook account you connected, or as itself, from an AgentMail address you set up.
What your recipients see at the bottom of the email
From your Gmail or Outlook account, through the plugin. The email carries your name and address, and usually no signature. Google's Gmail API reference describes the Gmail signature as "included in messages composed with this alias in the Gmail web UI", and Outlook adds its signature in its own compose window. An email a plugin sends through the mail provider's API skips both, so it ends wherever the Bot's text ends. To the recipient, it looks like you wrote a short note and forgot your details: no title, no phone number, no company line, and none of the legal footer your company may need.
From an AgentMail address. The email comes from a fresh address with no signature saved anywhere, so it ends with whatever sign-off the model writes. AgentMail lets you put a Bot on your own domain on paid plans, which helps recipients trust the address; the signature still has to be added by the Bot.
From Gmail or Outlook in the Bot's own browser. A Bot can also work in websites on its cloud computer. If it writes an email in Gmail's or Outlook's web compose window, signed in as you, the signature saved in that account would normally be added, as it is for you. We have not tested this route, and xAI's docs recommend connectors over the browser where a connector exists.
How to put your signature on every email a Grok Bot sends
- Get your signature as text. Make it free on Signatoro, or open the one you have, and click "Copy as text".
- Give it to the Bot once. Tell the Bot: "End every email you send with this signature, exactly as written:" and paste the text below it. xAI says Bots keep context on how you like work done; if you use skills, saving the instruction as one keeps it in a single place.
- Keep drafts on until one email checks out. Send yourself a test, open it from your Sent folder, and check the signature appears once, at the end. Only then consider "Disable drafts for this Bot".
- For a Bot on AgentMail, treat the Bot as its own sender. Give it a signature of its own, the way the AgentMail signature page describes, so the Bot's name, the company and a way to reach a person appear on every email.
Signatoro's Grok guide covers each Grok route step by step, including the xAI API, where your own code fetches the signature from Signatoro's API before each send and always gets the current version.
Why the signature matters more once drafts are off
With drafts off, nobody reads the email before it leaves, and the signature is the one part of the email you can fix in advance. It tells the recipient who is accountable for the message and how to reach them. For a company, it can carry a registered-office line or a confidentiality notice that the law or the company's own rules expect; on Signatoro's larger company plans, the owner sets one footnote line that goes under everyone's signature (see pricing).
Two more reasons to set this up before turning drafts off:
- Disclosure rules now reach agents. The European Commission's July 2026 guidelines on the EU AI Act say AI agents that interact with people should disclose both that they are AI and on whose behalf they act. AI email disclosure covers what that can look like in an email.
- Your name on an email can carry legal weight. Courts have treated a typed name or an automatic signature block as signing an email. Can an email your AI agent sends bind you? walks through the cases; keep drafts on for anything that reads like a commitment.
Grok Bot email questions
Can Grok Bot send emails from my Gmail?
Yes, once you add the Gmail plugin and sign in. As of October 7, 2026, xAI's changelog describes Bots sending through Gmail and, from version 0.60.0, sending from Outlook after you review a draft. Since version 0.64.0 you can choose "Disable drafts for this Bot" so that Bot sends directly.
Does Grok Bot have its own email address?
As of October 7, 2026, a Bot sends from the Gmail or Outlook account you connect, and a Bot-owned address comes from AgentMail, an independent company whose plugin is listed in the Grok Bot plugin browser. A RuntimeWire report found unannounced, switched-off code for @mail.grokbot.com addresses in the Windows app; xAI has not confirmed it.
Why don't emails from my Grok Bot include my signature?
Gmail and Outlook add your saved signature in their own compose windows. A Bot that sends through the Gmail or Outlook plugin skips those windows, so the signature is not added. Give the Bot your signature as text and ask it to end every email with it, then check one sent email.
How do I stop Grok Bot from sending emails without asking me?
Keep drafts on. With drafts on, a Bot shows each email as an editable card, and nothing sends until you choose "Send email". If you turned drafts off for a Bot, xAI's changelog says to ask the Bot to turn drafts back on.
Is AgentMail made by xAI?
AgentMail's own FAQ calls it "an independent company" and says the plugin listing is the extent of its relationship with xAI.
