Domains
Send and receive on your own domain instead of the default address.
By default a project sends and receives on its built-in address. Connecting your own domain moves both directions onto it: you add the DNS records the dashboard shows, verification runs, and the project's mail switches over.
Domain setup and verification live in the dashboard. Agents can read a
project's domains and their verification state through the list_domains
tool on the hosted MCP server.
The full setup guide — records, verification states, troubleshooting — is being written for this section.
