About Sailthru

Sailthru operates as a cross-channel marketing platform specializing in personalization, catering to retail and media companies. The company was founded in 2008 by Neil Capel, Ian White, and Chris Chapman. Capel's background in leading large-scale web systems and his family's history as greengrocers in England, focusing on meaningful customer interactions, shaped the vision for Sailthru—to offer personalized experiences at scale. White, who served as CTO, brought technical expertise from his previous role as the first head of engineering at Business Insider.

The firm's core business revolves around helping brands build stronger relationships with their customers by personalizing experiences across email, websites, and mobile applications. Its business model is centered on providing a comprehensive marketing solution that integrates customer data to deliver tailored messages and content. Revenue is generated through this platform, which helps clients like Bloomberg, Samsung, and Business Insider to increase customer retention and revenue. In December 2018, Sailthru was acquired by Campaign Monitor and became part of the newly formed CM Group, now known as Marigold.

The Sailthru platform offers a suite of features designed to automate and personalize marketing efforts. Its personalization engine uses proprietary technology to track user behavior across various channels to build a detailed interest profile for each customer. This allows for the automatic population of communications with relevant content and product recommendations. Key features include a personalization engine, email manager, mobile SDK, site personalization manager, and prediction manager for forecasting churn. The platform also provides robust analytics and reporting tools, including performance dashboards and retention analytics, to measure campaign effectiveness. A flexible RESTful API allows for deep integration and programmatic interaction with the platform's features, enabling automated workflows like transactional emails and campaign scheduling.
