Outbound automation with quality gates

What it is

It runs daily. Leads get scored for fit, drafted outreach goes through a quality panel, sending is paced. Replies or bounces suppress the contact automatically. The contact universe holds 460,000 businesses.

The interesting part is the gate. Every message is judged by four model reviewers on different lenses before it can send. The models themselves are A/B tested on copy quality with blinded panels. The system is as careful about what it says as who it says it to.

Under the hood

• Full pipeline: source, enrich, qualify, draft, gate, send, monitor, log. Each stage writes state the next stage reads.
• A four-judge quality gate on every message, each judge scoring a different lens. Anything that fails gets redrafted, not sent.
• Model A/B testing with blinded judge panels ranking which model writes the best outreach for each campaign.
• A suppression chain that writes back automatically: a reply, a bounce or a complaint removes the contact everywhere.
• A bounce and complaint circuit breaker that pauses the campaign before a reputation problem becomes a blocked domain.
• 1,200 sends a day at a paced rate, with CRM stage transitions synced to OnePageCRM.

What was hard

Making the automation trustworthy. Sending is easy. Sending 1,200 messages a day that a human would have written, without burning a domain or annoying the wrong person, is a quality-control problem. The judge panel and the circuit breaker are the answer: the system proves its work before the send. It stops itself on evidence of harm.
