These platforms offer robust notification infrastructure with strong developer experience, flexible workflows, and multi-channel messaging capabilities.



### What features do alternatives offer that Courier does not?

Courier lacks native preset template availability and voice messaging features, which are offered by some alternatives. It also has limited customization options and less automation capability compared to alternatives like Knock and Customer.io.



### Which Notification Infrastructure tools do reviewers recommend instead of Courier?

Reviewers highly recommend [Knock](https://www.g2.com/products/knock-knock/reviews) for its ease of use, powerful workflow builder, excellent customer support, and flexible API that supports multi-channel notifications including email, SMS, and in-app messages. [OneSignal](https://www.g2.com/products/onesignal/reviews) is praised for its intuitive dashboard, fast setup, and comprehensive omnichannel messaging including push, email, SMS, and voice messaging. [Customer.io](https://www.g2.com/products/customer-io/reviews) is favored for its advanced automation, segmentation, and personalization features, enabling highly targeted customer journeys across email, SMS, and push notifications.

### Why do users choose Knock over Courier?

Users choose [Knock](https://www.g2.com/products/knock-knock/reviews) over Courier primarily for its superior product quality and advanced feature set. Knock's workflow system, including batch aggregations and multi-environment support with git-like commit and promotion workflows, is highlighted as far better and more reliable than Courier's, with far fewer bugs and issues reported. Knock's API and SDKs are praised for flexibility and robustness, enabling complex notification workflows and integrations with multiple providers like Twilio and Segment. Knock's customer support receives high marks, with rapid, detailed responses often within minutes during business hours, and a strong Slack community for real-time assistance. The platform empowers both developers and non-technical users, allowing marketing teams to manage campaigns and templates independently, which significantly boosts productivity. Additionally, Knock's ability to centralize notifications across channels (email, SMS, push, in-app, Slack) and its intuitive UI for managing workflows and templates make it a preferred choice. Users also value Knock's scalable architecture, extensive integrations, and continuous product improvements, which justify its higher pricing compared to Courier. These factors collectively drive users to select Knock for complex, enterprise-grade notification needs.
