How to build an AI email agent that auto-replies to order status queries

Ecommerce support inboxes are dominated by 'where is my order?' messages, which require only a simple database lookup to resolve. A developer tutorial from Nylas demonstrates how to set up an AI agent with its own dedicated email inbox — such as orders@yourstore.com — to handle these queries automatically. The agent uses Nylas's Agent Account feature, a programmatic mailbox tied to a domain rather than a personal login, to read incoming emails and send replies within the same thread. It looks up order and tracking details from the store's own database and responds without human involvement for routine cases, escalating unmatched queries to a human. The approach aims to automate the repetitive 80% of order-status emails using existing Nylas API endpoints, requiring no new data-layer concepts for developers already familiar with the platform.
