The communications infrastructure for serious operators.
SpamMaster is a single, sovereign control plane for outbound mail, perimeter shielding, and carrier-grade telephony. Built for teams that treat deliverability, identity, and voice as a craft — not a SaaS line item.
Most platforms rent you a feature. SpamMaster gives you the building.
We replace the spaghetti of seven vendors — your SMTP relay, anti-bot, dialler, recording archive, compliance log, deliverability tool, and softphone — with a single, audited control plane your team actually owns.
Three disciplines. One control plane.
Carrier-grade voice
Telephony as a first-class citizen.
Asterisk + WebRTC, your trunks, your DIDs, your recordings. Predictive & preview dialler, Voice AI agents, IVR flows, real-time monitor, QA scorecards, coaching workflows, STIR/SHAKEN attestation, and a softphone that actually feels good in the ear.
Concurrent calls
12,000+
Outbound mail
Deliverability, not delivery.
MTA hashing, ARC, BIMI, warmup pools, inbox-placement tests, AI letter composition.
Perimeter
Shield against the noise.
Bot scanner, cloaker, signal analytics, custom rule engine and CAPTCHA — at edge.
Conversation IQ
Every call, transcribed and scored.
ASR + sentiment + keyword spotting feeds QA, coaching, and dispute defense.
Automation
Flows that survive audit.
IVR, callback, dispositions, business hours, skills routing, webhook fan-out.
AI operators
Voice AI agents on the same line.
Self-hostable LLM agents that join your queues, handle overflow, escalate cleanly.
004 / Posture
Built for the operator who answers to the regulator,the carrier, and the board — in that order.

One plan. Whole platform.
We don't unbundle. Mail, Shield, and Voice are sold as a single subscription — because that's how serious operations run them.
