Most "AI email" demos point a model at a human's inbox over OAuth. That's fine until you want the agent to be a participant — to have its own address that people reply to, that calendars invite, and that builds its own sender reputation. Pointing at someone's personal inbox doesn't give you that.
Nylas Agent Accounts take the other approach: a real name@yourdomain.com mailbox and calendar that the agent owns end to end. It sends, receives, hosts events, and RSVPs — and to anyone on the other side it's indistinguishable from a human-operated account. It went GA in June 2026.
The part I like as an SRE: it's not a new API surface. An Agent Account is just another Nylas grant. It gets a grant_id that works with every endpoint you already use — Messages, Drafts, Threads, Folders, Attachments, Calendars, Events, Webhooks. Nothing new to learn on the data plane.
This walkthrough provisions one two ways (CLI and raw API), then sends, receives, RSVPs, and adds guardrails.
