Overview

OneSignal is a customer engagement platform that unifies push notifications, email, SMS, and in-app messaging for mobile and web applications. Founded in 2011 in San Mateo, California, it has grown into one of the most widely used messaging infrastructure providers, delivering more than 8 billion messages per day.

The platform is particularly popular among app developers because of its generous free tier and straightforward SDK integration across major mobile and web platforms, making it a common default choice for startups and indie developers before they scale into larger engagement platforms.

Key Features

OneSignal supports multi-channel messaging (push, email, SMS, in-app) from a single dashboard, with audience segmentation, automated multi-step messaging journeys, and A/B testing built in.

Its 'Intelligent Delivery' feature optimizes send timing per individual user, and the platform provides delivery analytics, conversion tracking, and GDPR-compliant data handling for teams operating in regulated markets.

Pricing

OneSignal's Free plan covers 10,000 monthly email sends and unlimited mobile push notifications, making it usable at no cost for small apps.

The Growth plan starts at $19/month plus usage-based fees, while Professional and Enterprise tiers offer custom, volume-based pricing with expanded journeys, segments, and support for larger organizations.
