Run agent inboxes close to the data you already isolate

Enterprises already isolate CRM, documents, and model traffic. Then agent email appears and suddenly message bodies, attachments, and vendor threads want to live in a convenient SaaS region that does not match the rest of the control plane. The fix is architectural: keep agent inboxes close to the data you already isolate, with residency stated as a requirement rather than a hope.
Residency as a first-class requirement
If personal data in mail falls under 152-FZ or similar regimes, mailbox storage and processing locations matter. Choose a region you can defend in a questionnaire. Align Agent Inbox data-plane placement with where Neuro OS runs roles and where connectors are allowed to pull enterprise systems. Describe the actual pattern in plain language: self-host or VPC-deploy the agent runtime, and keep mail residency explicit in the design review. Do not depend on a vaguely named regional SKU to explain your architecture—write down where bytes live and who holds keys.
Self-host Neuro OS beside the mail plane
Neuro OS roles, skills, and sandboxes can run in infrastructure you control. Server-side connectors reach internal systems without copying credentials into prompts. Pair that with mailbox hosting in the same regulatory boundary so a single incident response plan covers both. Encryption at rest, key ownership, and retention schedules should match existing document policy—not a special email exception invented under deadline pressure.
Map which subprocessors touch attachments, headers, and bodies. If a scanning service leaves the region, call that out and decide consciously.
Network and access patterns
Prefer private connectivity where your security standard requires it. Agents read mail through APIs from sandboxes that cannot reach the open internet except via approved egress. Humans use forwarding into Neuro OS queues when judgment is required, still inside the same boundary. Outbound send remains Ask-gated; residency does not replace approval, and approval does not replace residency.
What to ask vendors and yourselves
Where is message content stored? Who holds keys? How is deletion proven? Can you export threads? What subprocessors touch attachments? How do you pin a region? Write the answers into the project repo next to the role definitions so audits do not depend on chat history or a slide that aged out of date.
Operating payoff
Teams adopt agents faster when security review is a configuration exercise instead of a one-off exception. Place the inbox near the isolated systems the agent must already touch. Keep Neuro OS as the governed runtime and Agent Inbox as the mail identity layer—co-located with the constraints you already accepted for the rest of the company, including 152-FZ where it applies.
Migration without a dual-write mess
If you start in a shared region and later must move for residency, plan export and cutover before volume grows. Dual-writing mail without a clear primary creates inconsistent threads and broken message-ids. Prefer an early residency choice aligned with Neuro OS placement, then grow. Moving mail later is possible; it is never free.
Agent Inbox gives each role a mailbox people can reply to, with forwarding into Neuro OS when a human must see the thread. Outbound mail defaults to Ask. Run the role on Neuro OS. To scope the first inbox, get started.
