“Omni migrated us from PMTA to KumoMTA without a hiccup. Warmups finally stuck. Gmail & Yahoo deferrals dropped, and our revenue jumped the same month.”
25+ Years • Bulk Email Infrastructure
Inbox Better. Warm Up Faster. Scale Smarter — with KumoMTA + Magic SMTP.
I’m Omni Knoweth. I build, fix, and scale high‑volume email systems for serious senders — from fast IP/domain warmups to rock‑solid infrastructure that respects ESP rules and lands mail where it matters.

Who I Am
25+ Years in Bulk Email — Builder, Operator, Problem‑Solver
I’ve lived and breathed deliverability long before it was trendy. I built Magic SMTP, managed countless infrastructures, and now harness KumoMTA — a modern, secure MTA that fixed what legacy stacks couldn’t: reliable warmups, speed, and ESP‑compliant sending.
✓
Hands‑on expertise across MailWizz, Interspire, Postal, and custom stacks.
✓
Migration specialist: Move cleanly from PowerMTA to KumoMTA without drama.
✓
Operator mindset: I tune for outcome — inbox placement, not just pretty graphs.
Important Note
I don’t provision/deploy PMTA anymore — I migrate it to KumoMTA.
If you have an existing PowerMTA setup, I can migrate you into KumoMTA with clean shaping, provider rollups, and modern security. Expect safer warmups and better reputation.
Already on PMTA? Perfect. Let’s move you to a future‑proof stack.
