OneSignal is a customer engagement platform that brings mobile push, web push, SMS/RCS, email and in-app messaging into a single system. It is designed to help teams onboard new users, build engagement habits and reduce churn through lifecycle automation, with AI-assisted tools for drafting, sending, testing and optimizing campaigns.

Core capabilities include Journeys, a visual workflow builder for cross-channel automation, plus segmentation, personalization, A/B testing, analytics, message throttling, localization and permission prompts. SDKs are available for Android, iOS, Flutter, React Native, Expo and Unity, and the platform connects with analytics tools, CDPs, data warehouses, CRMs and automation services such as Segment, Snowflake, HubSpot, Zapier and OpenAI.
