FAQs

  • What counts as a notification sent for usage billing purposes?
    A notification sent is a single notification delivered to a single user on a single channel. For example, if a workflow triggers both an in-app message and an email, that counts as two notifications sent.
  • Do you offer volume discounts?
    Yes, volume discounts are available on the enterprise plan.
  • Does Knock sign BAAs for HIPAA-compliant customers?
    Yes, Knock is HIPAA compliant and will sign BAAs for Enterprise plan customers.
  • What happens if I exceed the free plan limit without a billing method?
    Knock doesn't hard cap notifications. If you exceed your limit, they'll contact you about setting up a billing method for the following month.
  • Do I still pay for downstream messaging services with Knock?
    Yes, Knock does not currently manage billing for downstream platform providers that deliver notifications.
