Knock Channel Leverage Ladder

Knock's economics reward agencies that climb channels per client rather than adding clients per channel. A single lifecycle workflow built from a natural language prompt in Claude, ChatGPT, Cursor, or Grok can fan out to email, SMS, push, in-app, and chat, so the marginal delivery cost of the second and third channel is configuration time, not a new platform. The Starter tier at $250/month bundles 50K messages, 2.5K guide active users, and 2,000 AI agent credits, which means an agency can run several small-to-mid client journeys before message volume forces a plan conversation. Practical read: take a funded SaaS client live on email plus in-app first, then add push and SMS once the trigger logic proves out, and price the retainer against channels orchestrated rather than workflows shipped. Enterprise per-customer branding and custom roles are what let one workspace serve multiple client brands without cross-contamination.
