OneSignal review
Broad mobile automation with a free plan and a $19/month entry tier.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
OneSignal is a cloud-based customer engagement platform for app developers, marketers, and businesses. It brings together mobile push notifications, in-app messaging, email, SMS/RCS, web push, Live Activities, and automated Journeys. Teams can build visual workflows, trigger campaigns from custom events, segment audiences, personalize messages, run A/B tests, and review mobile and campaign analytics. Its mobile coverage includes iOS and Android, alongside web, desktop, Chrome extensions, and API access.
Pricing gives smaller teams a low-cost entry point. The Free plan costs $0 per month and includes all channels, basic automation and analytics, OneSignal AI and MCP, basic personalization, up to 1,000 monthly active mobile users, and 3 active Journeys. Growth starts at $19 per month, includes 5 active Journeys, 20,000 free email sends monthly, and standard A/B testing. Mobile push and web push add usage-based charges at their listed rates. Professional and Enterprise use custom annual pricing, adding capabilities such as advanced marketing and analytics, all integrations, advanced permission management, unlimited personalization, reporting history, security and compliance features, and a custom SLA.
OneSignal fits teams that want multiple engagement channels and a visual automation layer rather than a mobile-push-only tool. Integrations with Mixpanel, Segment, Amplitude, Snowflake, Google BigQuery, AppsFlyer, and Adjust support analytics, data, and mobile measurement workflows. CSV, API, and event-stream exports add flexibility for downstream systems. Choose OneSignal when broad channel coverage, behavioral triggers, testing, and low initial cost matter. Consider an alternative if usage-based billing, custom annual pricing, or the Free plan’s mobile-user limit does not fit your operating model.
