Run product notifications and lifecycle journeys on one platform, with visual editing, provider failover, and preferences per tenant, billed per send instead of per profile.
Updated November 2026
Courier is built for product, growth, and engineering teams working on the same notifications. You pay per send, so a large customer database you message lightly doesn't drive your bill.
Compare Courier and Customer.io on workflows, preferences, and pricing, or build your first journey.
Your growth team edits an onboarding journey in the Journeys canvas and Design Studio while engineering connects the product events behind it. Everything in the UI is on the API, so engineers and AI agents work on the same journeys and templates. Courier ships a hosted preference page, an embeddable preference center, and preference APIs, and fails over between 50+ providers automatically.
Braze prices by monthly active users, publishes no rates, and has no free plan. Courier publishes its price: $0.005 per send, with 10,000 free sends a month to start, and your transactional notifications run on the same platform as your journeys.
Iterable sells through its sales team, with no public pricing page. With Courier you can build and send your first journey today on the free plan, and see exactly what it will cost at your volume.
