What is Knock?

Knock is a notification infrastructure platform that handles the complexity of sending notifications across email, SMS, push, in-app, Slack, and other channels. Instead of building notification logic, preference management, batching, and delivery tracking from scratch, Knock provides APIs and SDKs that handle the entire notification lifecycle.

For startups adding notifications to their product, the naive approach — sending an email when an event occurs — quickly becomes complex. Users want notification preferences. Multiple channels need different templates. Notifications need batching (not 50 separate emails for 50 comments). Knock handles all of this complexity.

Key Features for Startups

Multi-channel delivery sends notifications across email, SMS, push (iOS, Android, web), in-app feed, Slack, Microsoft Teams, and Discord from a single API call. Define a notification workflow once — Knock routes it to the right channels based on user preferences.

Notification preferences give users control over which notifications they receive and through which channels. A user might want in-app notifications for comments but email notifications only for @mentions. Knock provides a pre-built preferences UI component and handles the preference logic server-side.

Batching and digest combine multiple notifications into a single message. Instead of sending 20 emails for 20 likes on a post, Knock batches them into "20 people liked your post" — with configurable batch windows and digest schedules.

In-app notification feed provides a pre-built React component for the notification bell that users expect in modern applications. Unread counts, mark-as-read, real-time updates, and infinite scrolling — all handled by the component.

Workflow builder creates multi-step notification flows. When a comment is posted: check if the recipient is online (if yes → in-app notification; if no → wait 5 minutes, then send email). Add delays, conditions, and branching without code.

Template management with a visual editor creates notification content per channel. Email templates with HTML/CSS. Push notification templates with title and body. In-app templates with rich content. Each channel gets appropriate formatting.

Who Should Use Knock?

Startups building products with user notifications that span multiple channels. Teams tired of maintaining custom notification infrastructure (email sending + push + in-app + preferences). Products where notification quality affects user engagement and retention. Any application where "users want notification preferences" is becoming a development project.

Knock vs Building Custom Notifications

Custom notification infrastructure requires email sending (SendGrid), push notification service (OneSignal), in-app feed (custom React), preference management (custom database), batching logic (custom code), and delivery tracking (custom analytics). Knock replaces all of this with one platform.

Knock vs Novu

Novu is open-source notification infrastructure with self-hosting. Knock is managed with better workflow building and preference management. Novu for self-hosting and open-source flexibility. Knock for managed service with polished developer experience.

Knock vs Customer.io

Customer.io is a marketing automation platform that sends lifecycle emails and push notifications. Knock is notification infrastructure for product notifications. Customer.io for marketing messages. Knock for product notifications.
