# Global Components Before you start activating Email Routing Rules, you'll need to install two globally-scoped Inbound Actions in your environment. These components allow Postmaster to begin routing inbound email to your ServiceNow instance. To install the Global Components, visit **Yansa Postmaster AI -> Install Global Components** in your left nav. Follow the prompts to Install or Update the components. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
