Go Beyond Journeys

There are over 7 billion people on the planet. Each one is unique. Your marketing can be too. With Sailthru, take control of the entire customer lifecycle—in email, on your website and in mobile apps, all from one source. Proactively engage based on individual customer behaviors, rather than spending your time building journeys that few customers take.

Personalize Experiences

What’s the feeling you get when you walk into a local coffee shop and the barista remembers you by name? Or you shop at your favorite local store and the owner offers recommendations tailored to your interest? Personalization matters, and consumers presented with personalized marketing are more engaged and spend more money. At Sailthru, we make it easy to personalize and automate marketing. Whether you call it 1:1, microsegmentation or something else, this is true, modern personalization at scale.

Predict Behaviors

Data science has redefined marketing. Today we can reliably predict the next actions of each consumer—when, where and how they will engage (in email, on the web, or via his or her mobile phone), purchase or even disconnect. Retailers and publishers trust Sailthru’s predictions to forecast lifetime value, identify untapped revenue opportunities, consume more content, purchase more products, and increase segmentation sophistication.
