Let the bot email customers from your own domain

Overview
The poster set up a custom-domain mailbox as an MCP connector for Grok Bot, plus a webhook so new mail triggers an automation.
Workflow
Suggested implementation: Create a mailbox on your own domain and connect it to Grok Bot as a custom MCP connector. Add a webhook to trigger a Grok automation upon receiving new messages, as incoming mail does not automatically wake the bot. Human role: Configure the webhook signature and verify the connection.
Reported result
Actual outcomes are unknown due to source unavailability. Proposed acceptance check: Verify that the bot successfully receives and responds to a test email sent to the custom domain address.
Human role
The original post does not say how a person stayed involved.
Limitations
Prerequisite: Access to a custom domain and Grok Bot API. Constraint: Grok automation webhooks reject bearer-token requests with 400 errors; only signed requests using the provided whsec_ secret work. Source reliability is low as the original post is inaccessible.
Try it
I need to set up a custom-domain email integration for Grok Bot. First, create a mailbox on [replaceable: your_domain.com] and configure it as an MCP connector for Grok. Second, set up a webhook that triggers a Grok automation when a new email arrives. Crucially, ensure the webhook uses the whsec_ secret for signing, not a bearer token, to avoid 400 errors. Before going live, perform a dry run: send a test email from [replaceable: test_sender@example.com] to the new address and confirm the bot responds. I will manually verify the webhook signature configuration and the bot's response logic. If the test fails, check the webhook logs for signature mismatches. Do not publish or send real customer emails until I confirm the dry run was successful.
