The default spam settings on an agent mailbox are a guess. They might be too loose — phishing and junk land in your support agent's inbox and your model dutifully drafts a reply to a Nigerian prince. Or they're too aggressive — a customer's reply from a slightly-misconfigured small-business mail server gets flagged, and your "always reply within 5 minutes" SLA quietly breaks because the message never reached the agent.
Most people building on top of an inbox treat spam as something the provider handles invisibly, and never touch it. That's fine for a human's inbox — a human sees the spam folder, eyeballs false positives, and corrects course. An autonomous agent doesn't. It acts on what arrives, and never notices what got filtered. So the spam threshold stops being a background convenience and becomes a parameter you actually have to set per agent.
On Nylas Agent Accounts, you set it on a policy. The policy carries a spam_detection block with three knobs — a DNSBL toggle, a header-anomaly toggle, and a spam_sensitivity dial — and you attach that policy to a workspace so every agent in the workspace inherits the same spam posture. Different class of agent, different policy, different threshold. That's the whole idea, and it's what this post walks through.
I work on the Nylas CLI, so the terminal commands below are the exact ones I reach for when I'm wiring this up. Every step shows both the raw API call and the CLI equivalent, because half the time I'm in a provisioning script and the other half I'm poking at a single workspace from a shell.
The grant is still the grant
Quick grounding, because it's easy to overthink this. An Agent Account is just a covers domain auto-grouping).

— domain auto-grouping and the default workspace, so you can set up one workspace per agent archetype.

The data plane never changed — it's the same grant-scoped mailbox the whole time. All you did was decide, per class of agent, how much junk gets to reach it.
