We operate
PostMTA team runs the control plane and Kumo nodes. You get panel access, audit exports, and SLA-backed operations — ideal when you want MailOps outcomes without hiring a relay team.
Enterprise
PostMTA Hosted
Managed KumoMTA control plane for high-volume outbound — operated by us or deployed in your VPC. No public pricing; every engagement starts with architecture and volume review.
How we price: volume tiers are quoted per engagement based on recipient count, dedicated vs shared Kumo fleet, and SLA tier. Air-gap default uses prepaid credit grants; STRIPE_* checkout is optional when enterprises want self-serve top-up. Seecredits +how we priceon the appliance.
Battle-tested to 100% on a fresh host: make battle-test+ make smoke-deep pass. Audit ledger atECC verify.
Deployment models
We operate — or you own the metal
Both paths ship the same smoke-gated appliance: Supabase control plane, Hono BFF, SMTP proxy, Kumo inject, credits ledger, OmniFBL.
Your VPC
Appliance installs on your cloud or bank metal. You hold attestation and network boundaries; we provide packaging, policy templates, and optional managed support.

Separate from DIY
Not postmta.com self-install
PostMTA Hosted is a distinct product line from the open self-install PostMTA on postmta.com. Same Kumo DNA — different go-to-market and support model.
