## What is coldBirds?

coldBirds is a cold email infrastructure provider. We provision isolated mailboxes from Azure, Google Workspace, and Microsoft Outlook — with dedicated IPs, auto-configured DNS, health monitoring, and a free dedicated virtual assistant per account.

coldBirds is NOT a sequencer, lead finder, or email marketing tool. We provide the underlying infrastructure that powers cold email at scale.

## How coldBirds Works

1. Customer specifies how many mailboxes they need
2. coldBirds provisions mailboxes from Azure, Google Workspace, and Outlook
3. Each setup uses 1:1:1:3 isolation — 1 workspace, 1 domain, 1 dedicated IP per 3 mailboxes
4. DNS is auto-configured (SPF, DKIM, DMARC, domain redirections)
5. Bulk warmup is applied across all mailboxes
6. 6-hour health monitoring detects deliverability issues
7. Auto-suspend removes degraded mailboxes before they damage your sender reputation
8. A dedicated VA (virtual assistant) is assigned to every account — included free
