Sender Engine
Runs campaigns, replies, dashboards, audit, and worker-backed execution.
AI-NATIVE OUTBOUND ENGINE
AI-native outbound that turns budget into live market coverage, reply intelligence, and qualified pipeline.
You set the budget. The engine buys and warms the sending infrastructure, researches your market, writes and tests the campaigns, and sorts every reply that comes back. You just talk to the buyers.
Every $1,000 at this level buys ~9,000 emails and ~35 replies
Expected monthly operating range. Results depend on market, offer, list quality, and response handling. Month one builds and warms the fleet; the engine reaches this range from month two.
What your budget buys
You pay one monthly number. The engine does every job below — the same jobs an outbound team of five would split between them. Minus the five people.
No setup fees, no per-seat pricing, no “data credits” sold separately. The number on the slider is the number.
The 2026 problem
Google and Microsoft enforce sender rules ruthlessly now. One wrong DNS record, one cold mailbox pushed too hard, one volume spike — and delivery quietly drops toward zero. There is no warning email. Campaigns keep “sending”; nothing lands.
Any single red step zeroes the pipeline — and most teams never learn which one killed them.
Humans make mistakes. Even brilliant ones. Especially tired ones.
So we asked the obvious question:
What if there were no humans in the error path… at all?
So we removed them. All of them.
The whole craft — domains, DNS, warmup, daily volume, copy, replies — now runs as software. It holds Google’s and Microsoft’s current sender rules and re-checks them continuously — while you sleep. Run this way, outbound becomes the most cost-efficient pipeline channel a B2B company can operate. The channel was never expensive. Operating it by hand is.
One human stays — the operator who supervises the engine and joins your scan call. No humans in the error path. One human in the relationship.
People who can run outbound correctly are rare, busy, and price like it. Most companies will never hire one.
Cheap outreach vendors resell templates over rented tools — no infrastructure of their own, no learning loop, no results.
We digitized the full craft into AI. Setup, research, copy, replies — the whole process runs as software, at a budget a normal company can pay.
The machinery
These are not features on a slide. Each module below is production software we built, deploy daily, and run our clients’ campaigns on right now.
Runs campaigns, replies, dashboards, audit, and worker-backed execution.
Controls sender infrastructure, warmup, domain/mailbox health, and deliverability posture.
Runs real AI research loops over market evidence and preserves the dossier for operator decisions.
The loop
Market analysis, competitor mapping, evidence, ICP hypotheses.
Source-backed segments and account logic.
Campaign angles, sequences, variants, experiment design.
Safe sender infrastructure and paced outbound.
Replies, positive replies, objections, segment feedback.
Dashboard, alerts, quality control, deliverability truth.
Every cycle feeds the next. The loop compounds.
Client Hub
Every client gets the Client Hub: replies the minute they land, a CRM your team can work leads in, the research dossier behind your campaigns, response-speed tracking. Not a weekly PDF. No other outbound operator gives clients a cockpit.
Replies land here the minute they arrive — answer them yourself, or let your team take them.
Cost per lead
Take the budget. Divide it by what comes back. No asterisks — the same slider, the same table, one division.
What we count — so nobody plays word games:
Expected monthly outbound email volume across all sequence steps.
All human replies captured and available for triage, including neutral, negative, and irrelevant replies.
Replies that indicate business interest, curiosity, referral, problem-fit, or openness to continue.
Positive replies that survive qualification — counted conservatively as half of positive replies.
Straight answers
Not in week one — and you should distrust anyone who promises that. The first weeks build and warm the sending fleet: domains, mailboxes, weeks of warmup. Volume ramps through month one, and the slider ranges describe the engine at operating temperature — from month two on. The research and the campaigns are ready well before the fleet is.
No. The engine builds a dedicated sending fleet around your brand — separate domains, separate mailboxes — and operates it for you. Your primary domain and its reputation stay untouched.
Three things. Approve the research and the copy in your Client Hub, talk to the buyers who reply, and answer them fast — reply speed is where pipelines are won. Everything else is the engine’s job.
Everything in the assembly line above: domains, mailboxes, warmup, market research, contact sourcing, copywriting, sending, reply sorting, and the Client Hub for your whole team. No setup fees, no per-seat pricing, no data credits. Pay by card, bank transfer, or crypto — all three are first-class.
Because you couldn’t verify them — and in this market, logo walls and case studies are routinely inflated or invented. Our clients’ outbound is confidential. Instead we show the actual system you’d be operating — the Client Hub above — and build a market scan for your company before you pay anything.
The economics say it can’t be. Spray-and-pray dies in the spam folder and takes the sender’s infrastructure with it. The engine survives only by doing the opposite: paced sending under provider ceilings, researched targeting of people who can reasonably expect the message, tested copy, and instant suppression of anyone not interested.
An AI engine, supervised by the human operator who built it — and that’s the person on your scan call. No sales team, no account managers, no handoffs. The one human you talk to runs the system that does the work.
The AI field review usually finishes within the hour. If your intake clears the gate, the engine prepares your pre-call market scan and booking arrives by email. Nothing is ever sent to your market without your approval: campaigns launch only after the call, the agreement, and your sign-off on the copy.
The gate
This form is longer than you expected, on purpose. Every answer becomes research input, and that research is why your first campaign comes out specific instead of generic. The AI reviews every field — thin answers come back to you.
