The
Infrastructure Layer
Most cold email fails before a single word gets read. This playbook starts where others don't: inbox setup, domain config, DNS, mailbox provisioning, and warm-up rules that actually protect your sending reputation.
The Full
Tech Stack
20+ tools mapped end to end. InboxKit, Clay, Apollo, HeyReach, Bitscale, BetterContact, Prospeo, and more. Source, enrich, verify, send. In that order, every time.
The System
that Runs Itself
From A/B testing and deliverability monitoring to Fireflies-powered content engines and automated morning briefings. This is the operational layer serious cold email teams are quietly building.
