PushEngage vs. Courier

PushEngage is a customer engagement platform built for mid-market and enterprise eCommerce brands that want to grow retained revenue without increasing acquisition spend or engineering load. When paid channels plateau and CAC keeps climbing, PushEngage helps retention and growth teams shift revenue to an owned, high-intent channel: real-time Web and App push notifications — fully driven by marketing, not developers.

Courier is notification infrastructure for customer messaging, built for humans and AI agents. It sits between your app and every channel you send on: email, SMS, push, in-app inbox, chat, and webhooks. You send one request, and Courier works out where it goes, what it looks like, and whether the user wanted it at all. Teams use it for the messages a product has to send: onboarding, alerts, receipts, reminders, and account notices. You keep the providers you already pay for. Courier is the layer above them.
