Send shipment updates from a logistics email agent

Short summary

Nylas Agent Accounts let logistics teams own a real mailbox that sends proactive milestone updates (picked up, in transit, delivered) and automatically answers reply queries like 'where's my freight?' by looking up shipment data in their TMS. Unlike one-way ESPs, agents handle both directions in a single email thread with real DKIM/SPF signing and no OAuth token expiry.

• •Agent Accounts provide a two-way email channel: TMS fires milestone events, your code sends emails; customer replies trigger webhooks to query shipment status and respond in-thread
• •Same API endpoints work for reads and writes via the grant_id; no new platform concepts beyond standard Nylas Messages/Threads/Folders endpoints
• •Setup via Nylas CLI (brew install), then provision mailbox, publish DKIM/SPF records, map thread_id to shipment in your database
