What does OneSignal do?
OneSignal is a customer engagement platform that helps businesses communicate with their users through multiple channels. The service enables sending push notifications to web and mobile apps, email campaigns, and SMS/text messages from a single interface. It provides tools for managing audience segments, scheduling messages, and tracking delivery performance across different communication methods.
The platform works by integrating with websites and mobile applications through SDKs and APIs. Once connected, businesses can create targeted messaging campaigns based on user behavior, preferences, and demographics. OneSignal handles the technical infrastructure needed for reliable message delivery across various platforms including iOS, Android, and web browsers. The service includes analytics to measure open rates, click-through rates, and other engagement metrics.
OneSignal is particularly useful for mobile app developers who need to re-engage users, e-commerce sites sending order updates, and content platforms notifying subscribers about new posts. Marketing teams use it for promotional campaigns, while customer support teams send transactional messages. The platform scales from small startups to large enterprises with high-volume messaging needs.
