Quick Navigation


The Framework: Four Layers of Marketing Automation

Layer 1: Email Sending

The core capability — writing, designing, and sending emails. The real question is which model matches your business.

Layer 2: Automation & Sequencing

This is where email becomes a system. Triggers, sequences, and behavior-based logic.

Layer 3: CRM & Contact Management

Your system of record: who your users are, what they’ve done, and where they are in the funnel.

Layer 4: Workflow Integration

The connective tissue between your tools — website, payments, CRM, and internal ops.
