About Knock
Knock is notification infrastructure for sending lifecycle and transactional messages across email, in-app, push, SMS and chat. It can be set up through an agent tool as well as through code.
What it does
Teams build workflows in a visual builder, using triggers, delays, branches, batches and channel steps. The platform handles delivery across channels and can run an agent step inside a workflow to personalize content for each recipient. Workflows can be tested before they are published, and analytics show how messages perform after they go out.
Key features
- Visual workflow builder
- Email, in-app, push, SMS and chat channels
- Delays, branches and batches
- Agent step for personalized content
- Performance analytics
Who it's for
Knock suits developers and product teams that want to send onboarding and transactional messages without building delivery systems. Growth teams that run many workflows across several channels will also find the builder useful.
Pricing and good to know
Review the pricing page for current tiers before you choose a plan. Test each workflow before you publish it, so mistakes are caught before real users receive messages. Keep an eye on your sending volume, since costs can grow with the number of messages and recipients.
