Customer Engagement
3,757 of the 1,000,000 top sites in our Tranco top-1M census run OneSignal (0.4%). A push-notification and customer-messaging service for sending alerts to web and mobile app users. Detection is homepage-level HTML/header fingerprinting, so a site can run OneSignal on other pages without it showing here.
