our call
Start with Retention Science — highest vibe code, weakest moat.
Emotive
Conversational SMS with humans in the loop.
you can rebuild
- abandoned cart flow
- basic segmentation
- event tracking
- campaign sender on top of an ESP API
what you lose
- deliverability infrastructure and IP reputation
- years of historical customer data
- mature platform integrations
- compliance across regions
real moats
- deliverability engineering and ISP relationships
- proprietary engagement data
- integration ecosystem
Retention Science
Building basic email trigger workflows and template rendering using modern AI agents is trivial. Replicating managed IP deliverability, real-time predictive churn algorithms, and send-time optimization models takes substantial effort and continuous data.
you can rebuild
- Basic event-triggered email flows (welcome series, abandoned cart, post-purchase)
- RFM-based rule segmentation (Recency, Frequency, Monetary value)
- Standard HTML email template rendering
- Ecommerce event webhook ingestion (Shopify, BigCommerce)
- Basic metrics dashboards (open rates, click-through rates, revenue per email)
what you lose
- Predictive send-time optimization trained on cross-merchant interaction logs
- Automated product recommendation engine driven by collaborative filtering
- Managed domain reputation and dedicated warm IP pool routing
- Pre-built ML models for predicted Customer Lifetime Value (pCLV) and churn probability
- Enterprise handling of compliance edge-cases for CAN-SPAM, CASL, and GDPR
real moats
- Aggregated cross-merchant behavioral data powering predictive engines
- Managed email delivery infrastructure and established ISP relationships
- High switching costs associated with migrating established email workflows and sender domain reputation
Questions people ask
Which is easier to rebuild with AI, Emotive or Retention Science?
Retention Science. It scores 4/10 on vibe code with a moat of 5/10, so an AI-assisted MVP takes about 2-3 weeks and a full replacement about 6-12 months, due to deliverability infrastructure and predictive ML model tuning.
Which one costs less, Emotive or Retention Science?
Emotive at $200/mo/mo for a typical mid-market store. The gap between the two is about $6,600/mo a year.
