This stack, applied to you.
For product teams, Next.js + Knock centralizes multi-channel notifications behind one API. Knock manages user preferences, channel routing (email, SMS, push, in-app), batching, and digest. Send from server actions, render in-app feed via React SDK. The team avoids the inevitable mess of triggering emails from 5 different services.
product teams-specific gotchas
- Pricing scales with messages — model carefully
- Email deliverability is on you (Knock routes to providers like Resend)
- Workflow versioning needs care — test before deploying
- Test mode is essential for engineering
- Per-user preferences need UX design
A B2B SaaS centralizes all notifications (email + Slack + in-app) on Knock. Workflow definitions in dashboard; triggers from app code. The team replaces a hodge-podge of Resend + Twilio + custom code with one tool.
Common product teams questions.
What about Courier?
Real alternative. Courier has similar shape; Knock has cleaner DX in 2026.
Can we just use Resend + Customer.io?
For simple cases yes. For complex multi-channel with preferences, Knock saves significant complexity.
