What it handles
Inbox OS handles the volume so your team handles the decisions.
Payment & invoice questions
AI drafts a grounded reply from your billing FAQ. A human reviews it before it sends — always.
Automatic folder routing
Rule-based routing runs before the AI. Billing emails always land in the right folder without LLM overhead.
Disputes, legal & complaints
Any email matching dispute or legal patterns is immediately escalated to your team. Never auto-replied. Never delegated.
Bounce & NDR filtering
Delivery failure notifications are classified and silently removed from the review queue. Zero noise.
How it works
No workflow builder, no prompt engineering. Four clear steps and you're live.
Connect your Microsoft 365 mailbox
Authorise with your Microsoft account in minutes using standard OAuth 2.0. No admin privileges required. Delegated permissions only.
Add your policy docs to the knowledge base
Paste your billing FAQ, payment terms, and refund policy in plain text. The AI indexes them and uses them to ground every reply it drafts — no hallucinations.
Set 3–5 routing rules
Define simple rules: Subject contains "invoice" → Billing folder. Body contains "dispute" → Escalate to human. Rules run before the AI — fast, deterministic, zero tokens wasted.
Review, approve, and send
Every AI-drafted reply waits in your review queue. You approve it before it sends. Inbox OS never sends anything without explicit human approval.
