PushEngage vs. Knock

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.

Knock is infrastructure for sending product and customer messaging. Ship cross-channel product notifications and lifecycle messaging that drives engagement, growth, and retention. Knock has everything you need to power notifications for your product, including: - A powerful workflow engine to automate and manage your entire cross-channel motion, from in-product messaging to email and push notifications. - Branded, in-product messaging components, including embeddable inboxes, feeds, and lifecycle messages. - Broadcasts make it easy to send effective, one-time messages to custom audiences.
