Sailthru

Sailthru is an email marketing automation platform powered by machine learning, with a particular strength in behavioral segmentation. The engine analyzes how individual customers interact with your content or products, then automatically groups them into segments that respond well to specific messages. It works especially well for retailers and publishers automating product and content recommendations.

If you're managing high volumes of personalized content recommendations or running sophisticated email programs for a retail or publishing brand, Sailthru's ML segmentation can save significant manual work. It's less of a one-size-fits-all platform and more of a specialist tool for teams that want data-driven, behavior-based automation.
