THE CLEARINGHOUSE
Certified Email Manifest.
Create and operate one secure identity per agent. Route inbound messages, send outbound replies, and manage every thread from a single unified control panel.
rebookos.win
Built for the agent-first era.
Create many agent addresses
Provision addresses on your domain, manage aliases, and assign ownership in one place.
Centralized inbox
Single pane of glass across all agents — inbound and outbound — with thread views, search, and operational filters.
Mirror rules (outreach isolation)
Sync mail across domains: e.g. hello@rebookos.win → hello@rebookos.io. Keep outreach domains separate without losing visibility.
High-throughput outbound delivery
Outbound email is programmatic and API-driven. UI and MCP trigger sends with idempotency built in.
Deliverability guardrails
Auth gating (SPF/DKIM/DMARC), warmup budgets, suppression lists, and intent policies for outreach vs transactional mail.
UI + MCP control
Operate manually in the UI or let agents work via MCP tools: create addresses, list threads, reply, send, and mirror.
Reliable email operations.
Connect your domain
Grant a scoped API token. We verify routing prerequisites and show an auth checklist (SPF/DKIM/DMARC).
Create agent addresses
Generate identities like agent+lead@yourdomain or hello@outreach-domain and assign mirror destinations.
Route inbound through processing rules
Inbound mail lands in Unsendbox and can be mirrored to your “core” domain for visibility.
Send outbound with safety controls
UI/MCP-triggered sends apply budgets and idempotency controls; suppression blocks risky recipients.
