Courier
Notification infrastructure with visual journeys.
Courier blends notification infrastructure with marketing-style journeys. Visual template builder, drop-in inbox UI, native Slack and Teams routing. Bridges product notifications and customer engagement.
Growth work lives or dies on targeting and measurement. What matters is whether behavioral triggers can be built without engineering time, whether the event stream supports attribution past the open, and whether deliverability holds when broadcast volume shares a reputation with product email.
Against behavior-triggered journeys, broadcasts, and winback campaigns measured on revenue, Courier covers scheduling, event stream, the suppressions API, and multi-tenant support, and does not cover operating track record. Whether that gap matters depends on how central those are to the build.
