About

Most attribution tools tell you which ads a customer clicked before buying. That is correlation. Causality Engine tells you what would have happened to your revenue if you had never run those ads. That is causation. We use causal inference, the same statistical methodology behind clinical drug trials, to calculate the incremental revenue each marketing channel actually generates. Not touched. Not assisted. Actually caused. The math is simple: if Meta reports 4.2x ROAS but your total revenue stays flat when you cut spend by 30%, those conversions were going to happen anyway. Causality Engine quantifies exactly how much. Connect your GA4 and Shopify data. Get your first causal analysis in under 5 minutes. No tracking pixels, no cookies, no complex integrations. Just upload your data and see which channels create real growth and which ones take credit for growth that was already happening. One-time analysis: $99. Continuous intelligence: $299/month.

About

InboxStack is an email deliverability intelligence platform built around Brain, a proprietary causal AI engine that identifies why emails miss the inbox — not just that they did. Most deliverability tools stop at monitoring: they show a drop in inbox placement or a blocklist hit and leave you to investigate. InboxStack goes further, correlating signals from your ESP, DNS authentication records (SPF, DKIM, DMARC), Google Postmaster Tools, Microsoft SNDS, and 50+ blocklists through a causal knowledge graph built on a 22-year deliverability knowledge base — tracing the actual root cause, whether it's a DKIM misalignment, IP reputation dip, or content trigger. Onboarding starts with forwarding your email headers for an instant DNS/auth audit, no migration required. Teams that want ongoing monitoring can connect their ESP and Postmaster accounts, with optional seed testing for real inbox-vs-spam placement data. Built especially for digital agencies and ESP's.

Currently using tools like Triple Whale, Northbeam, or native platform dashboards and questioning whether the numbers reflect reality.
