## What Knock is

Knock is a platform for developers and agents managing product, marketing and transactional messaging. It supports teams that need to coordinate communications across customer channels.

It sends messages through email, SMS, push, chat and in-app channels. Knock ingests data from warehouses, CDPs, reverse ETL tools and webhooks, then creates dynamic segments from attributes, events and relations. Workflows can be triggered by API calls, usage events or changes to a segment. It also provides in-app guides through pre-built or custom components.
