Cold Email Infrastructure Built for 95%+ Inbox Placement
We register the domains, provision the mailboxes, configure SPF/DKIM/DMARC, run the warmup, and monitor blacklists daily — so your sending stack is production-grade from day one, and your primary domain stays protected.
The Complete Sending Stack
Six layers, configured per-client, owned and operated by us. No DIY, no DNS pain, no surprises.
Secondary Sender Domains
Look-alike domains registered, configured, and rotated to protect your primary domain reputation.
- 3–10 domains per account
- Brand-safe naming patterns
- Registrar managed by us
- Full ownership transfer on exit
Mailboxes & Workspace
Google Workspace mailboxes provisioned, branded, and connected to your sending platform.
- 2 mailboxes per domain
- Sender names & signatures
- Workspace-level controls
- 2FA on every mailbox
SPF / DKIM / DMARC
Authentication records configured strictly — DMARC quarantine policy active from day one.
- SPF with strict include chain
- 2048-bit DKIM signing
- DMARC quarantine policy
- BIMI-ready record set
Automated Domain Warmup
14–21 day gradual ramp that builds sender reputation before a single prospect email goes out.
- 5 → 30 sends ramp curve
- Realistic reply & threading
- Spam-rescue + folder moves
- Continuous low-volume warmup
Inbox & Domain Rotation
Smart sending logic distributes daily volume across domains and mailboxes — never overloading any one sender.
- 20–30 sends/mailbox/day cap
- Round-robin domain rotation
- Automatic sender failover
- Sequence-level pacing rules
Daily Monitoring & Alerts
Blacklist, placement, and authentication checks every 24 hours — anomalies pause sending automatically.
- 30+ blacklist databases
- Weekly placement tests
- Bounce & spam-rate alerts
- Auto-pause + delisting workflow
From Zero to Production-Ready in 21 Days
A fixed-timeline, four-phase build that ends with a clean handoff document and a sending stack you'd never set up alone.
Audit & Strategy
Review your current sending posture, target volume, and ICP. We pick the domain naming pattern, sender count, and mailbox layout.
Provisioning
Register domains, provision Google Workspace, configure DNS (SPF/DKIM/DMARC/MX), brand signatures, and verify every record.
Warmup Ramp
Automated 14-day ramp from 5 to 30 sends per mailbox per day. Realistic threading, replies, and spam-rescue patterns.
Handoff & Monitoring
Connect to your sending platform, hand over the infra doc, and switch on daily monitoring + alerts. Production-ready.
Why Our Infrastructure Lands in the Primary Inbox
Deliverability isn't luck — it's six engineering decisions made correctly, every time.
The six layers that decide inbox placement
Most cold-email failures trace back to one of these layers being missing or misconfigured. We treat each as its own discipline.
Secondary domain isolation
Look-alike domains keep cold-email reputation off your primary brand domain.
Strict authentication
SPF + DKIM + DMARC quarantine — the records mailbox providers actually check.
Gradual warmup
14–21 day ramp simulating natural conversation patterns before any cold send.
Conservative volumes
20–30 sends per mailbox per day, hard cap. Scale by adding domains, not pressure.
Triple-layer verification
Every contact validated through ZeroBounce + NeverBounce + MX-record check.
Daily monitoring
Blacklist + placement tests every 24h. Anomalies trigger auto-pause within hours.
