Grok Bot 如何绑定自有域名邮箱：Shipmail MCP 连接器与 Webhook 自动化指南

Blog

Short answer

Ask Grok Bot to claim an inbox and it gets an address ending in @mail.grokbot.com. That is fine for sign-ups and tests. For mail that goes to customers or partners, give Grok Bot a mailbox on your own domain instead: connect it through Shipmail's MCP connector, and add a Shipmail webhook that starts a Grok automation when new mail arrives.

On October 9, xAI gave Grok Bot its own email address. Grok Bot can now sign up for services, contact businesses and schedule meetings from an inbox that is not yours. It is a good idea, and we have been telling people to give their agent its own address for a while. The catch is the domain. Every address ends in @mail.grokbot.com, and for anything a customer sees, you want it on yours.

What xAI launched

Where a mail.grokbot.com address falls short

For sign-ups, trials and verification codes, the built-in inbox is enough. It keeps that mail out of your own inbox, which is the point. The problems start when the address talks to people who matter to your business.

There is also the risk every agent inbox has. Anyone who knows the address can email it, and a message can contain text written to look like an instruction. Keep what the agent is allowed to do small, whichever inbox it uses.^[3]

Three ways to give Grok Bot email

Give Grok Bot an address on your domain

Create a mailbox such as bot@yourcompany.com in Shipmail and connect Grok Bot to only that mailbox. Its mail then goes out from your domain, replies land in a mailbox you own, and you or a teammate can open it any time.

1. Step 1

   Create the mailbox

   Add bot@yourcompany.com in Shipmail. Solo is $4/month and includes 2 mailboxes, one for you and one for Grok Bot.

2. Step 2

   Add the connector on grok.com

   Open Connectors, choose New Connector, then Custom, and enter https://shipmail.to/api/mcp. Grok Bot uses the connectors on your Grok account.

3. Step 3

   Sign in as the bot's mailbox

   On the Shipmail sign-in page, use the bot mailbox's address and password. The connection then reaches that one mailbox and nothing else.

4. Step 4

   Pick the permissions

   Start with Read and draft. Grok Bot writes drafts, and you send them. Move to sending once you trust what it writes.

Start Grok when new mail arrives

A connector lets Grok read the mailbox when it is working. To have it start on its own when an email lands, use a Grok automation with a Webhook trigger. Each trigger has its own URL and signing secret, and Grok only runs requests signed with that secret.^[4]

1. Step 1

   Create the automation in Grok

   On grok.com, open Automations and create one. Add a Webhook trigger, check that the Shipmail connector is on, and write the instructions, for example: "When this fires, the body has the sender, subject and message ID of a new email. Open that email in bot@yourcompany.com with the Shipmail connector. Answer it as a draft if it is a simple question, otherwise send me a summary." Save it, then copy the endpoint and the signing secret. Grok shows the secret only once.

2. Step 2

   Add a webhook in Shipmail

   Under Developer, then Webhooks, create a webhook with the automation's endpoint, the message.received event and only the bot's mailbox. Paste Grok's secret, which starts with whsec_, into Standard Webhooks signing secret.

3. Step 3

   Send a test

   Use Send test event on the webhook, then email the bot's address from your own. Grok accepts the event right away and queues a run. In our test, the run showed up under Executions a few minutes later.

Keep it safe

• Connect only the bot's mailbox, by signing in with its own password. Your inbox stays out of reach.
• Keep Read and draft until you have read a few weeks of its drafts.
• Scope the webhook to the bot's mailbox, so nothing else starts the automation.
• Revoke the connection under Developer, then Connections, if something looks wrong. No password change needed.

FAQ

Questions worth answering

Common questions about Grok Bot email.

How do I get a Grok Bot email address?

Ask Grok Bot to claim an inbox, or tag @bot on X. The address ends in @mail.grokbot.com. On a team account, an admin has to enable the feature first.^{Sources[1]Grok Bot: Grok Bot now has its own email[2]TeslaNorth: Grok Bot starts handing out its own email inboxes}

Can Grok Bot use my own domain?

xAI has not announced own-domain support for the built-in inbox. To use your domain today, connect a mailbox on your domain through Shipmail's MCP connector instead, and Grok Bot reads and sends from that address.^{Sources[2]TeslaNorth: Grok Bot starts handing out its own email inboxes[10]Shipmail MCP server docs}

Can I see what Grok Bot received and sent?

With a Shipmail mailbox, yes. It is a normal mailbox: open it in the Shipmail app or any mail client, and a teammate can take over a thread.^[10]

Can Grok Bot react as soon as an email arrives?

Yes. Point a Shipmail webhook for message.received at the Webhook trigger of a Grok automation, and paste the trigger's signing secret into the Shipmail webhook. The event carries the sender, subject and message ID, and the automation opens the email through the Shipmail connector.^{Sources[12]Shipmail webhooks documentation[4]xAI docs: Grok automation webhooks}

Can Grok Bot send email without asking me?

Not if you connect with Read and draft. Grok Bot can then only leave drafts, and you send them.^[11]
