Right Now, Your Emails Are Going to Spam. You Just Don't Know It Yet.
Cold email infrastructure that protects your deliverability — on autopilot.
coldBirds provisions isolated mailboxes from Azure, Google Workspace & Outlook — with dedicated IPs, auto DNS, 6-hour health monitoring, and a dedicated VA per account. So you can scale outreach without inbox fires.

Why Isolation Is Everything
Most providers pile 50+ mailboxes on shared IPs. When one triggers a blacklist, they all go down. coldBirds doesn't work that way.
Shared IPs (Everyone Else)
Blast Radius
50+ mailboxes
All down. All at once.
coldBirds 1:1:1:3 Isolation
Blast Radius
3 mailboxes
Contained. Everyone else keeps sending.
You've always suspected shared IPs were killing your inbox placement rates. You were right.
The math: 200 mailboxes on shared IPs = all 200 at risk from a single bad sender. 200 mailboxes on coldBirds = max 3 affected, the rest keep sending.
How coldBirds Works
From zero to fully isolated, monitored infrastructure in under 4 hours — not weeks.

Choose your volume (5 to 1,000+). Pick your provider mix — Azure, Google Workspace, or Outlook. That's it.
We provision the full infrastructure
coldBirds creates isolated workspaces: 1 domain + 1 dedicated IP per 3 mailboxes. DNS (SPF, DKIM, DMARC) configured automatically. Warmup starts immediately.

A trained virtual assistant manages your dashboard, handles onboarding, and provides proactive support. Responds in under 2 hours. Included free with every account.
We monitor. You scale.
Every 6 hours, we check inbox placement across all mailboxes. Degraded mailboxes auto-suspend before damaging your domain. You focus on closing deals.
