OneSignal
Push and messaging platform with ML-driven send-time optimization.
About
OneSignal is a customer messaging platform covering push notifications, email, SMS, and in-app messages through one API and dashboard. Its Intelligent Delivery feature uses machine learning on each user's session activity to send messages at the moment they are most likely to engage, which the company says performs substantially better than manual scheduling.
Beyond timing, it offers segmentation, frequency capping, A/B testing, and automated journeys, plus predictive segments. The platform processes billions of notifications daily, and a free tier lets teams test with real users before upgrading.
