How We build Your
sending infrastructure.
acme.com is Acme's real website. We never send cold email from it — so its reputation is never at risk.
We register a handful of close lookalike domains (you approve the names) and provision them through Zapmail. If one ever gets flagged, your main domain is untouched.
Three Google inboxes per domain — enough volume to scale, few enough that every provider treats each mailbox like a normal person. That's 21 mailboxes in total.
These are the ID badges every inbox provider checks before letting mail in. We set all three on every domain — so you land in the inbox, not spam.
Each sending domain redirects to acme.com, so a curious prospect who clicks the domain lands on your real site. Whole setup: ~1 day.
We warm the inboxes
so they land in the inbox.
Every mailbox is enrolled in a warm-up network the moment it's created — before a single prospect sees it.
The inboxes send and reply to each other like real people, day after day, gradually ramping volume.
Providers learn these are real senders — opens, replies and zero spam complaints push the trust score up.
After ~14 days the inboxes have a healthy reputation and are ready to send to Acme's prospects.
We find
Acme's buyers.
Candidate companies pour in from 12+ channels at once — Prospeo, Apollo, Sales Navigator, an Apify scraper cluster (Maps, jobs, Shopify, Product Hunt…), Serper, communities and niche directories. Far wider than any one tool.
We keep only right-fit companies for Acme — size, industry and buying signals — and drop the rest before paying to enrich a single one.
Clay routes 100+ providers, Prospeo FIRMO returns 35 firmographic fields in one call, and a smart-scrape cascade (Serper → parallel.ai) reads each site. OpenAI turns it into per-lead variables.
2–3 real buyers per company. Prospeo finds most in-house; on a miss a backup chain fires — Surfe → MixRank → OpenMart — first hit wins.
Each email runs a finder waterfall — Kitt → LeadMagic → Prospeo → Findymail — then a strict TryKit verify before it's allowed in. Bounce rates stay near zero.
Live signals in.
Six to eight campaigns out.
Job posts, LinkedIn announcements, funding rounds, product launches, tech-stack changes and community mentions — all watched continuously for Acme's ideal buyers.
A new BDR hire, a Series A raise, a Product Hunt launch — each is a company actively spending right now. Not a cold guess: a live event.
Signal attaches to the company, we find the decision-maker, and the copy hook writes itself around what just happened.
Because they're already in motion, not stationary. Signals outperform pure firmographic segments in almost every sprint.
Each signal type becomes its own campaign in Sprint (Step 05) — job-signal, funding-signal, launch-signal each get their own angle, offer and subject line. Always fresh, always warm.
We don't run one campaign.
Six to eight, in parallel.
We break Acme's list into a deliberate mix — verticals (industry), roles (persona), and buying signals (active intent) — so each campaign speaks to one type of buyer.
Recently funded, a BDR hire, a Product Hunt launch — these are companies actively spending right now. Signal-based segments consistently reply first.
Every segment gets its own angle, offer and subject line — never one message duct-taped across the whole list.
Every experiment runs at the same time. No favorites — real replies pick the winners.
Top 2–3 campaigns double their volume. Underperformers pause and get rewritten. Every week we compound what's working.
We write it,
personally — at scale.
Some come straight from the data (name, company, headcount). Others are written by AI from each lead's research — even the subject line.
It reads the scraped facts — Series A timing, no sales hire yet, headcount — and infers the tension none of them state outright, then writes the opener from it. Not a slotted token: a sentence composed for one person.
Data variables and AI variables slot into a proven template, so every email reads like it was written by hand for that one person.
The same offer runs through three value lenses — save time, make money, save money — so the best-performing message wins on real replies.
Each angle becomes a short sequence over the next week, every touch adding something new — so Acme stays top-of-mind without nagging.
We go live
and the replies come in.
After warm-up, Acme's first campaign launches in Instantly across all 21 mailboxes.
Around 24 emails per inbox per day, spaced out — never a blast — so providers keep trusting your domains.
Because the domains are warmed and authenticated, messages land in the primary inbox, not spam.
Positive replies come straight back to you@acme.com, and sending auto-pauses on reply so no prospect is ever double-messaged.
Reply lands.
Sub-sequence fires. Meeting booked.
Acme's campaign goes out — an initial cold email, plus one follow-up. Standard so far; every agency does this part.
Someone from the list writes back with real interest. This is the moment where most agencies stop the automation and hand it off — hope for the best.
The reply triggers a second round of enrichment: their latest LinkedIn posts, news, role changes — data that wasn't there when we first emailed.
2–3 follow-ups, each written around something we just learned. Not templates — a real thread that keeps the momentum moving toward a meeting.
Because the sub-sequence keeps the conversation warm, replies convert to calls — not drift into a "maybe later." That's the piece other agencies miss.
The infrastructure
looks after itself.
Every send, open, reply and bounce is tracked — the moment a metric drifts, the system flags it.
Every one of Acme's mailboxes is scored on its own reputation. If one dips, it's pulled and rested before it can drag the others down.
Each sending domain is checked against blacklists and reputation feeds continuously — a problem domain is caught early, not after a whole campaign burns.
Weak inboxes rest, warm replacements rotate in, campaigns keep sending. The infrastructure looks after itself so Acme's sending stays evergreen.
