The AI brain for email marketing
Cortex AMSES (Autonomous Marketing Strategy & Execution System) is an intelligence layer that sits on top of your email platform. Five AI agents cover the work of a strategist, an analyst, and an agency.
Book a demoNot another ESP. An intelligence layer.
Cortex doesn't replace Klaviyo, Braze, or Iterable. It sits on top of your existing email platform: your ESP handles delivery, while Cortex handles strategy, analysis, and competitive intelligence.
Intelligence layer
Sits on top of your ESP rather than replacing it. Your lists, templates, and sending stay exactly where they are.
Autonomous agents
Five AI agents research, analyze, plan, and draft continuously, and bring you the plan for approval.
Numbers you can audit
Every metric is computed in Python from your data, never generated by a language model, with a full trail back to the source.
Why we built Cortex
Email teams keep adding tools and retainers, yet the strategy itself is still written by hand: someone exports the data, someone reconciles the numbers, and someone guesses what competitors are doing.
We built Cortex to close that gap. Competitor monitoring that runs on its own, analysis computed from your real data, and a weekly strategy that arrives written, so your team spends its time deciding instead of assembling.

Why companies switch to Cortex
The usual setup is a strategist, an analyst, an agency retainer, and a stack of tools, each with its own invoice. Cortex covers that work with one subscription and one login.
Plans, currencies, and annual billing are all on the pricing page.
