Domain Infrastructure

Overview

Cold email deliverability depends entirely on infrastructure decisions made before the first email is sent. The domain names, mailbox providers, DNS configuration, and rotation strategy form the foundation on which all outbound rests. A poor infrastructure setup will produce poor deliverability regardless of copy quality or targeting precision.

This skill produces a complete domain infrastructure plan: which secondary domains to register, how to provision mailboxes across providers (Google Workspace, Microsoft 365, Zoho), DNS authentication configuration for each domain, inbox rotation schedules, and a monitoring framework to detect degradation before it impacts campaigns.
