Company profile

researched Aug 2026

Retention Science, also referred to as ReSci, sells artificial-intelligence-driven marketing automation software for ecommerce merchants. The core product automates and personalizes email messaging across stages of the customer lifecycle, including welcome sequences for new customers, repeat-purchase prompts, win-back campaigns for at-risk customers and cart-abandonment recovery. An optimization engine predicts subject lines, email content, send time, send frequency and product recommendations on the customer's behalf, while a drag-and-drop workflow editor lets marketers build conventional flows manually and choose how much of a campaign the AI optimizes.

The platform includes a customer data platform that integrates with ecommerce platforms and consolidates customer and prospect data into a unified view, then augments individual customer records with predictions such as customer lifetime value, next product purchased and churn likelihood for use in segmentation. Reporting features combine analytics, revenue reporting, visualizations and data mining, from top-level dashboards down to individual prospect behavior. SMS marketing is offered as a complement to email for multi-channel campaigns. Operationally, the service is delivered through components including a Cortex main dashboard application plus APIs for users, promotional and transactional sends, recommendations, filtering and segmentation, data imports, campaign reporting and event tracking.

Business model

Retention Science supplies a software platform to ecommerce brands, which provide campaign content while the platform learns, tests and optimizes their email and SMS messaging; customers are supported by assigned client success managers and API access.

Traction

The company states that hundreds of brands use the platform, collectively reaching more than 350 million customers each day, and cites client results of 60 percent higher email engagement rates and 45 percent higher purchase rates.

Full profile — market position, technology, go-to-market, geography

Market position

Positions itself as an AI-first ecommerce email marketing automation and customer data platform, competing on predictive optimization rather than purely manual campaign tooling.

Emphasizes that its AI predicts customer behavior and automatically optimizes individual email variables, reducing manual campaign work, while still allowing marketers to build and control traditional flows via a drag-and-drop editor.

Technology

The platform is built on predictive machine learning applied to unified customer data: a customer data platform ingests data from integrated ecommerce platforms and channels, and AI models generate per-customer predictions (lifetime value, next purchased product, churn likelihood) and optimize email variables such as subject line, content, delivery time, frequency and product recommendations. Delivery is exposed through modular services and APIs covering sends, recommendations, segmentation, data imports, tracking and reporting.

Go-to-market

Direct sales of the platform to ecommerce brands, supported by customer testimonials and integrations with leading ecommerce platforms; third-party lead-generation tools such as Retention.com can push acquired contacts into Retention Science lists via its API.

Ecommerce brands seeking to automate lifecycle email and SMS marketing; named customers referenced on the company's site include apparel brands Evelyn & Bobbie and Lime Ricki.

Geography

Headquartered in Santa Monica, United States, serving online brands; product signup and support are delivered online.
