Segmentation & Personalization: Build segments based on predicted next purchase date, lifetime value, browsing behavior, geography, and dozens of other data points.
Marketing Automation Flows: Visual workflow builder with 80+ pre-made templates for welcome series, abandoned carts, post-purchase, and win-back sequences.
