Overview
Courier and OneSignal both handle multi-channel messaging but differently. OneSignal sends messages directly — especially push notifications, where it dominates. Courier orchestrates notifications through providers. For our take on each, see our Courier comparison.
OneSignal's Push Dominance
OneSignal was built for push notifications and it shows. Unlimited free mobile push, rich notification support, detailed delivery analytics. No other platform matches OneSignal's push notification expertise. Courier routes push through providers like FCM and APNs but doesn't specialize in it.
Courier's Routing Value
Courier's value is in provider abstraction — route through different providers per channel, switch providers without code changes, build complex routing logic. If you need specific providers for compliance or performance reasons, Courier's flexibility matters.
The Sequenzy Alternative
For SaaS founders who need email specifically, Sequenzy combines transactional email and marketing campaigns with Stripe integration at $49/month — a different tool for email-focused needs.
