[H2] Scale confidently with proven reliability
OneSignal makes reaching customers seamless and scalable. Powering billions of messages daily, we help businesses of all sizes connect with their audiences in real time — across push, email, SMS/RCS, and in-app messaging — anywhere in the world.
View security & privacy

A customer engagement platform is the real-time intelligence engine that connects your user data to automated messaging across Push, Email, and SMS. Unlike legacy tools, a CEP like OneSignal uses a "feedback loop" of user behavior to deliver personalized value at every stage of the lifecycle, from initial onboarding to long-term retention.

OneSignal drives retention by capturing real-time micro-intents. By analyzing how a user interacts with your app, the platform triggers relevant messages, such as a personalized tip or a re-engagement offerat the exact moment the user is most likely to act. This outcome-led approach ensures your brand stays top-of-mind without causing notification fatigue.

OneSignal is a unified omnichannel orchestration hub. From a single dashboard, you can coordinate and send mobile push, web push, email, SMS, RCS (rich communication services), in-app messaging, and Live Activities. This allows you to reach users on their preferred channel with a consistent brand voice.

Intent-driven messaging replaces "one-size-fits-all" blasts with reactive communication. By setting up automated workflows that respond to specific user actions, like completing a tutorial or abandoning a cart so you ensure that every message is a direct response to the user's current needs, significantly increasing conversion rates.

Scheduled messaging follows a fixed calendar, while event-driven messaging follows the user. OneSignal triggers messages based on real-time "Events" (e.g., item_purchased or app_opened). This allows businesses to be agile, responding to user behavior the millisecond it happens rather than waiting for a pre-set campaign time.

Behavioral segmentation groups users based on their actual digital footprints, such as feature usage, purchase frequency, or last-active status. This level of granularity allows marketers to stop "guessing" and start sending hyper-targeted content that resonates with specific audience needs, resulting in much higher engagement per message.

Customer journeys are visual, multi-step workflows that guide users through a product experience. Using OneSignal’s no-code builder, you can create paths that branch based on user behavior (e.g., "If user opens email, wait 2 days; if not, send SMS"). This ensures no user falls through the cracks, regardless of how they engage.

OneSignal is built to eliminate the technical bottleneck. We provide powerful, lightweight SDKs and APIs that developers love for their reliability and performance, paired with an intuitive, no-code UI that empowers marketers to launch and iterate on campaigns without ever touching a line of code.

OneSignal enables personalization at scale by merging real-time data with liquid templating and dynamic content blocks. Whether you are messaging one hundred users or one hundred million, you can tailor every element, from the subject line to the image, based on unique user attributes and preferences.

OneSignal is built for speed and agility. While traditional marketing clouds are often "email-first" and require months of implementation, OneSignal is "mobile-native" and offers a much faster time-to-value. We provide the real-time, event-driven infrastructure that modern apps need to compete in an AI-driven world.

Yes. OneSignal maintains the highest industry standards, including SOC 2 Type 2, ISO 27001, and GDPR compliance. We offer robust data privacy controls and regional data residency, ensuring that your customer data is protected and that your brand meets all global regulatory requirements.

Absolutely. OneSignal is designed to grow with you. We power engagement for over one million businesses, ranging from early-stage startups to Fortune 500 enterprises. Our flexible infrastructure handles billions of messages daily, ensuring 99.9% reliability regardless of your audience size.
