Courier Review

Courier is a customer messaging platform designed to send notifications and manage messages across multiple channels like email, SMS, push, Slack, and in-app alerts. It helps teams orchestrate automated, personalized communication that improves user engagement without building complex infrastructure. Its main strength is offering a unified system to design, deliver, and track messages at scale. The tool shines in use cases such as transactional alerts, customer journeys, and lifecycle notifications, especially for SaaS, healthcare, and marketplaces. Results can be seen quickly since it provides ready-to-use APIs, SDKs, and visual editors, eliminating long setup times. Teams can start sending messages fast with minimal coding. Courier integrates into the go-to-market stack as a multi-channel messaging layer that complements CRMs and email services by routing and personalizing messages. It’s not a full CRM, chat platform, or marketing automation tool, so users looking for those should look elsewhere. Instead, it focuses strictly on notification delivery and orchestration.
