Cold email infrastructure built to scale.
We build, warm, and manage the entire sending infrastructure your outbound operation needs: domains, mailboxes, DNS authentication, warm-up, and daily monitoring. Fully managed, so you never worry about deliverability again.
Most cold email fails before a single message is sent. Bad DNS, shared infrastructure, no warm-up. It all adds up to spam folders. We eliminate that risk completely.
Fully managed by our team. You focus on selling.
Why most cold email never reaches the inbox.
Emails landing in spam
Poor DNS setup, no warm-up, or shared infrastructure tanks your deliverability before you send a single cold email.
Primary domain at risk
Sending cold email from your main domain is a ticking time bomb. One spam complaint can blacklist your entire business communication.
Inconsistent volume
Without proper mailbox rotation and send limits, you're either under-sending (wasting money) or over-sending (burning domains).
DIY setup that breaks
You followed a YouTube tutorial, bought 10 domains, set up mailboxes, and two weeks later half of them are in spam. No monitoring means no warning.
Six steps from zero to inbox-ready.
Domain strategy & acquisition
We register dedicated sending domains that mirror your brand, protecting your primary domain while building sender reputation from day one. The managed engagement includes 50; a build-and-handoff is sized to your volume.
Custom naming conventions, registrar diversification, automated renewal
Mailbox provisioning
Each domain gets 2 mailboxes configured with unique sending personas, proper display names, and signatures. On the managed engagement that is 100 inboxes ready to send, all mapped to your sending platform.
Google Workspace & Outlook, persona management, forwarding rules
DNS & authentication
SPF, DKIM, DMARC, and custom tracking domains configured correctly on every domain. This is where most DIY setups fail: one misconfigured record tanks deliverability across your entire operation.
SPF alignment, DKIM key rotation, DMARC policy, MX records
Warm-up orchestration
Every mailbox starts warming the day it is created, with realistic send patterns, reply simulation, and inbox placement monitoring. Campaigns go live in week two at a conservative volume and ramp as warm-up completes over days 14–21. We don't just warm. We verify deliverability before a single outbound email goes out.
Gradual volume ramp, engagement simulation, spam folder rescue
Sending platform configuration
SmartLead or Instantly: configured with inbox rotation schedules, daily send limits per mailbox, campaign-level throttling, and failover logic. The goal: maximum volume with zero deliverability risk.
Inbox rotation, send scheduling, bounce handling, blacklist monitoring
Ongoing monitoring & repair
Deliverability isn't set-and-forget. We monitor inbox placement rates, blacklist status, bounce rates, and spam complaints daily, and rotate or replace underperforming mailboxes before they hurt your campaigns.
Daily health checks, automated alerts, proactive domain rotation
Tools behind your infrastructure
We orchestrate the best sending platforms, registrars, and monitoring tools, so you don't have to manage any of them.

Who this is for.
Teams scaling cold email
You're sending 1,000+ emails/month and need real infrastructure, not 5 domains from GoDaddy and a prayer.
Agencies & service providers
You run outbound for clients and need a reliable infra partner who handles domains, mailboxes, and deliverability at scale.
Companies building in-house
Your SDR team is ready to send but you need the technical foundation built properly from day one, not duct-taped together.

We build and run it. You own it.
We build your cold email infrastructure and run it as part of the managed engagement. Prefer to run it yourself? We build it and hand over the keys, scoped on the discovery call. Either way, the domains and mailboxes are registered to you.

Your Infrastructure
The infrastructure is included in the managed service and registered in your name. You keep all of it, whether you continue with us or not.
- → Domains, registered in your name
- → Mailboxes, on your accounts
- → Sender reputation, built on your domains
Why you own it: There's no benefit to us holding your infrastructure. In your name, you're in full control, while the managed service covers the standard infrastructure and software.
Frequently asked questions
What teams ask us before they hand over their sending infrastructure.
How many domains and mailboxes do I need?
Most B2B teams sending 3,000–6,000 emails per month need 4–7 sending domains with 2 mailboxes each. The managed engagement includes 50 domains and 100 inboxes, so there is headroom to scale. For a build-and-handoff, we scope the exact footprint based on your target send volume, ICP size, and deliverability goals before any build starts.
How much does cold email infrastructure cost?
The managed engagement is $4,500/month + $1,000 one-time setup and covers the build, day-to-day running, sending infrastructure, software and reply handling in one scope. There are no separate infrastructure charges in the standard managed service. Domains and inboxes are registered in your name.
How fast can you get my infrastructure ready to send?
Your first campaign is live in about 14 days. Domain acquisition, DNS authentication (SPF/DKIM/DMARC) and mailbox provisioning happen in the first few days, and every mailbox starts warming as soon as it exists. By day 14, inbox placement is verified and your first campaign is live, starting at a conservative volume that ramps up as warm-up completes.
What happens if a domain gets blacklisted?
We catch it before it becomes your problem. Daily monitoring tracks inbox placement, blacklist appearances, bounce rates, and spam complaints. Flagged domains are rotated out and replaced, usually before a single campaign is affected. This is the orchestration layer most DIY setups miss entirely.
Do I actually own the infrastructure?
Yes. Every domain and mailbox is registered in your name from day one. If you ever stop working with us, you keep everything, no handoff drama, no vendor lock-in. That is the core of how we work: we build and manage the system, you own the asset underneath it.
