The Physics of Email Deliverability
Why emails go to spam (IP reputation, domain age, content scraping).
Outcome: Understand exactly how spam filters score your emails so you stop blaming your copy for your technical failures.
Domain & Workspace Architecture
Purchasing burner domains safely and setting up Google Workspaces at scale.
Outcome: Build an isolated infrastructure that protects your company's primary domain from being permanently blacklisted.
The Holy Trinity (SPF, DKIM, DMARC)
The exact DNS configurations required to cryptographically sign your emails.
Outcome: Configure bulletproof DNS records that tell Google and Microsoft you are a legitimate, authenticated sender.
Warming & Inbox Placement
What algorithmic IP warming actually does and how long it takes.
Outcome: Use automated warming pools to trick algorithms into seeing your new domains as high-reputation senders.
List Hygiene & Bounce Defense
Why a 3% bounce rate will destroy a domain and how to use APIs to prevent it.
Outcome: Implement a zero-bounce architecture that verifies every scraped email before it enters your sending queue.
Scaling & Inbox Rotation
How to send 5,000 emails a day by horizontally scaling workspaces.
Outcome: Load-balance your outbound volume across 50 different inboxes without triggering velocity penalties.
