Attentive is a strong SMS platform. Klaviyo is the B2C CRM that unifies your customer data across email, SMS, RCS, WhatsApp, and push, with segmentation, AI, and reporting that show what earned the revenue.
Email, SMS, RCS, WhatsApp, and push run off a single customer profile. Channel affinity uses each customer's past behavior and preferences to predict their best channels and dynamically routes each message where they're most likely to convert, with combined reporting across the whole program.
Rich customer data on a real-time profile powers segmentation and Composer, which builds a campaign, flow, or segment from a single prompt, grounded in your own data.
Multi-touch attribution across email, SMS, and push shows which messages actually drove sales, not just opens and clicks.
