Five Years Building Cold Email Infrastructure That Actually Lands
We're not a reseller with a landing page. We're two operators who've built thousands of sending systems — from single-domain startups to infrastructure sending millions of emails a day.
Who You're Actually Working With
No account managers, no ticket queues. You deal with us directly — the same people building your infrastructure.
Farhan has built thousands of cold email setups over the past five years — from single-domain launches to architectures capable of reaching millions of prospects a day. If there's a way to break deliverability, he's seen it and fixed it.
Sohaib handles inbox provisioning and the automation layer around it — the systems that turn a pile of configured inboxes into an outreach engine that runs without babysitting.
Most Cold Email Fails Before the First Send
Over five years of building outreach systems, we kept seeing the same thing: teams with good offers and good copy getting nowhere — because the infrastructure underneath was wrong from day one.
Misaligned SPF records. DKIM never configured. Every inbox stacked on one domain. Sending volume ramped from zero to hundreds overnight. The campaign was never the problem. The foundation was.
So we built the thing we wished existed: infrastructure done properly the first time, by people who've built it thousands of times. Domains structured for reputation isolation, authentication configured and verified, warmup handled, sending limits calibrated.
Today we serve 380+ agencies and outbound teams, most of them in the US — from founders sending their first hundred emails to operations reaching millions of prospects a day.
Built on Fundamentals
Authentication, reputation isolation, and controlled volume — the things inbox providers actually check.
Proven at Scale
From 3-domain startups to systems sending millions daily. The same principles, sized to your volume.
Direct Access
You talk to the founders, not a support queue. Same-day answers on WhatsApp.
24–48 Hour Delivery
Most setups live within two days. No drawn-out onboarding, no endless discovery calls.
Infrastructure, Inboxes, and Automation
Three things, done properly — so your outreach has a foundation that holds up as you scale.
Cold Email Infrastructure
Complete sending environments on Google Workspace, Microsoft 365, or Azure. Domains, authentication, warmup, and scaling architecture built for the volume you're targeting.
Inbox Provisioning
Reseller-priced Google Workspace and Microsoft 365 inboxes with SPF, DKIM, and DMARC configured — for teams that already have domains and just need inboxes done right.
Outreach Automation
Lead generation and cold email automations built around your infrastructure — the workflow layer that keeps campaigns running without constant manual work.
What You Can Expect

We size infrastructure to your actual sending volume — not the biggest package we could sell you.
No Hidden Fees
Plan prices include reseller accounts and full setup. No separate onboarding charges appearing later.
