About

Firebase Cloud Messaging (FCM) is a cross-platform messaging service that lets developers send push notifications or data messages to users on Android, iOS, and web apps at no cost.

It supports both notification and data messages (up to 4096 bytes), lets developers target a single device, groups of devices, or topic-subscribed devices, allows custom notification content (priority, TTL, custom data, sounds, scheduling), and integrates with Google Analytics to track delivery and engagement.

Klaviyo is a marketing automation and data platform that enables businesses to run email, SMS, mobile push, and web form campaigns using a unified customer database.

It provides real-time customer profiles with behavioral and purchase history, advanced segmentation based on hundreds of data points, and built-in AI for automated multi-channel flows, content generation, and predictive analytics such as next purchase date, churn risk, and lifetime value.
