Why Grok Bot

Built for the agent you already use.

Mermail gives Grok Bot a dedicated inbox and payment layer so verification, checkout, and receipts stay in the same loop.

Dedicated mailboxes instead of a shared personal Gmail login
Real inbound email with full thread context
OAuth-scoped access to one Mermail workspace
Persistent Bot routines can poll and handle new mail

Before you start

Questions, answered.

Fast fixes for auth, setup, and discovery.

Is Mermail an official Grok Bot plugin?+

No. Add it as a custom MCP connector; Grok discovers the hosted Mermail tools through OAuth.

Does Grok Bot need a Mermail API key?+

No. Use OAuth and add no custom headers. This keeps PayBox and x402 tools available.

Does each Bot get a separate email address?+

Bots share the connector, but each can reuse a dedicated Mermail mailbox for its own identity and threads.

Can a Grok Bot routine watch for new email?+

Yes. Schedule a routine to poll list_emails; email is not currently a native Grok Bot event trigger.
