Retention Science (ReSci)

Retention Science (ReSci) is an AI-driven email and SMS marketing automation platform for ecommerce brands. It addresses the manual work of segmenting customers and timing messages by using predictive models to personalize communications across the customer lifecycle, covering welcome, repeat purchase, win-back, and cart abandonment flows.

The platform includes a customer data platform (CDP) that syncs data from ecommerce integrations and enriches each customer record with predictions such as lifetime value, next purchased product, and churn likelihood. A drag-and-drop automation workflow editor lets users build their own flows, while AI can optionally optimize subject lines, email content, delivery time, frequency, and product recommendations. Reporting combines analytics, revenue reporting, and visualizations down to individual prospect behavior. SMS can be combined with email for multi-channel campaigns.

ReSci is aimed at ecommerce merchants of varying sizes and is also used by agencies serving their clients. It is part of the Constant Contact family of brands. The pricing page does not provide plan details, so information about free plans, trials, editions, or seat-based and usage-based packaging is not available here.
