Run an event waitlist with an email agent that promotes the first yes
Short summary
A tutorial for building an event waitlist agent using Nylas Agent Accounts that emails waitlisted attendees when a seat opens and confirms the first acceptance by reply arrival order. The agent owns its own inbox, threads replies, and uses webhooks to trigger seat allocation. The author emphasizes that atomic claim logic (Redis SET NX or Postgres row locks) must live in your own application, not in Nylas.
- •Agent Account owns waitlist@events inbox and sends offers autonomously
- •Arrival order from message.created webhooks determines who gets the seat
- •Atomic claim logic (Redis/Postgres) is application-side, not Nylas-managed
