Pros
- Unified notification API across channels
- Developer-friendly templates and workflows

- Good fit for product-led apps
- Easier setup than building notifications in-house
Cons
- Newer ecosystem than mature legacy tools
- Complex routing may still require configuration
- Analytics may be lighter than full comms platforms
- Usage-based pricing can grow with notification volume
Verdict
Knock does a strong job of making product notifications easier to build and maintain. It is best suited for product teams that want reliable delivery without maintaining their own notification stack. The main trade-off is that larger teams may outgrow its simplicity and need more advanced analytics or enterprise controls.
