Knock
Knock is an agentic customer engagement platform that orchestrates lifecycle and transactional messaging across email, SMS, push, in-app, and chat by accepting natural language prompts to Claude, ChatGPT, Cursor, or Grok. Unlike traditional marketing automation platforms, Knock builds workflows directly from AI agent instructions, eliminating the need for visual workflow builders or custom code. Agencies can white-label Knock (branding removal included in Starter at $250/mo) and resell it as a retainer to product-led SaaS, e-commerce, and messaging-heavy clients. The platform includes one-time broadcast capabilities, event-triggered automations, dynamic template systems, and cross-channel performance analytics in a single workspace.
Knock is an agentic customer engagement platform, priced at $250 a month on the Starter plan, integrating with Claude, ChatGPT, Cursor and Grok. InnovaAI rates it 5.8 of 10 for agency resale.
Agency Audit
Knock orchestrates lifecycle and transactional messaging across email, SMS, push, in-app, and chat by accepting natural language prompts to Claude, ChatGPT, Cursor, or Grok, then building workflows without code. Agencies managing client messaging journeys, especially product-led SaaS companies, can resell Knock as a white-label retainer by building client workflows, handling channel setup, and monitoring performance. The $250/month Starter tier (50K messages, 2.5K guide active users, 2,000 AI agent credits) supports small-to-mid client accounts; Enterprise plans with per-customer branding and custom roles unlock multi-tenant agency operations. Best fit: agencies with 3+ messaging-heavy clients who want to own the workflow layer without building custom orchestration.

- Your clients send lifecycle emails, SMS onboarding flows, or in-app feature announcements and currently use separate tools for each channel (e.g., SendGrid for email, Twilio for SMS, Segment for in-app).
- You want to offer AI-generated message personalization as a retainer upsell without building custom LLM integrations; Knock's agent steps let you prompt Claude or ChatGPT to write dynamic content per recipient.
- You manage 3+ client accounts and need multi-tenant workflows; Knock's Starter plan supports 2.5K guide active users and scales with per-message overage pricing.
- Your clients require HIPAA compliance or PCI DSS certification; Knock does not publish compliance certifications beyond SOC2 Type I.
- You need to white-label the entire platform with custom domain and branded client portals; Knock removes its logo but does not offer full domain white-labeling or custom portal branding in the Starter tier.
- Your clients send fewer than 5,000 messages per month and you cannot justify a $250/mo retainer; the Starter plan's 50K message allowance is overkill for small-volume use cases, and there is no lower-tier option.

Platform Features
Core capabilities of Knock
Multi-channel workflow orchestration
Build triggered automations and one-time broadcasts across email, SMS, push, in-app, and chat from a single workflow canvas. Agencies can manage all client messaging channels in one tool instead of juggling SendGrid, Twilio, and Segment separately.
AI agent-driven personalization
Prompt Claude, ChatGPT, Cursor, or Grok to generate dynamic message content per recipient within workflow steps. Agencies can offer AI-personalized onboarding emails and feature announcements without building custom LLM integrations.
In-app guide builder
Ship banners, modals, cards, and tooltips with custom components directly to end users. Agencies can deliver feature announcements and user education without requiring client engineering teams to embed SDKs.
Dynamic template system
Create on-brand email and message templates with reusable content blocks and variable substitution. Agencies can maintain consistent branding across all client campaigns and reduce template rebuild time.
Event-triggered automation
Trigger workflows based on user events (signup, failed payment, usage limit reached) and conditional branches. Agencies can automate lifecycle messaging without manual intervention or external workflow tools.
Cross-channel performance analytics
Analyze messaging performance across all channels in a unified dashboard. Agencies can report on email open rates, SMS delivery, push engagement, and in-app interaction in a single view.

Bottom Line
Knock orchestrates lifecycle and transactional messaging across email, SMS, push, in-app, and chat by accepting natural language prompts to Claude, ChatGPT, Cursor, or Grok, then building workflows without code. Agencies managing client messaging journeys, especially product-led SaaS companies, can resell Knock as a white-label retainer by building client workflows, handling channel setup, and monitoring performance.

Best fit: agencies with 3+ messaging-heavy clients who want to own the workflow layer without building custom orchestration.
Reality Check
Knock's pricing scales on message volume and AI agent credits, so high-volume clients (e.g., daily digest SaaS) will incur overage charges at $0.005 per additional message and $0.01 per additional AI agent credit. Agencies must manage separate billing relationships with Claude, ChatGPT, or other LLM providers, adding operational complexity. No published HIPAA or PCI compliance statement limits healthcare and fintech resale.

Why this category matters
The commercial case before the tooling.
Core concepts
The mental model you need to price and scope the work.
- Journey Debt CompoundingConcept
Journey debt is the accumulated maintenance obligation inside every live workflow: broken integrations, stale scoring rules, undocumented branches, and approvals that no longer match how the client actually sells. Unlike a bad campaign, journey debt does not surface in a single report; it surfaces as slower delivery, more exception handling, and margin erosion across the retainer. The framework says price the deployment against the journeys you will maintain, not the journeys you launch. A client with 12 active journeys and 4 integrations carries roughly triple the maintenance load of one with 4 journeys, even when both pay the same build fee. The category description makes this explicit: commercial terms should follow the actual number of journeys, integrations, approvals, and maintenance obligations. Forrester's October 2026 finding that governance and security teams operate without a shared working model is the same failure pattern inside an agency, where the person who builds the workflow is rarely the person who inherits its upkeep.
- Exception Path OwnershipConcept
Marketing automation platforms are sold on the happy path: lead captured, score rises, sequence fires, sales gets a clean handoff. The billable work lives on the exception path. Duplicate records, a lead who replies mid-nurture, a webhook that fails at 2am, a WhatsApp opt-out that never syncs back to the CRM. Agencies that map who owns each exception before go-live can price maintenance honestly; agencies that do not absorb the cost silently for months. The framework asks three questions per workflow: what breaks, who is paged, and what the client sees when it does. A concrete trigger came from OpenAI's October 6, 2026 Ironclad collaboration, where agents are trained to apply company-specific business rules inside specialized software. That is the same discipline agencies need for client journeys: encode the rule, name the owner, log the failure. Platforms such as ActiveCampaign, Brevo, and Manychat all expose the triggers; none of them decide who answers when one misfires.
- Handoff Baseline TransferConcept
Handoff Baseline Transfer treats the measurable operating baseline, not the platform login, as the deliverable that changes hands at the end of an engagement. A marketing automation build is only as valuable as the numbers a client can reproduce without the original builder: open and reply rates by journey, lead-to-opportunity conversion, list hygiene thresholds, and the named owner of each exception path. When those figures live in a spreadsheet the client cannot regenerate, the retainer is priced on dependency rather than on results. Agencies that document the baseline before launch can hand a client a working system and still charge for optimization, because the next phase is measured against a known starting point. The same discipline protects the agency when a client brings in a second vendor: the baseline is the shared reference, so scope disputes resolve against data instead of memory.
Decision and risk
How to judge the fit, and the ways it goes wrong.
- Marketing Automation Rule: Price the Journey Count, Not the Platform SeatEvaluation Rule
Count the journeys, integrations, approval gates, and monthly maintenance hours first, then set the retainer against that count instead of the number of platform logins.
- When Journeys Outnumber Your Documentation, Cap the Retainer Before You Add Channel FourEvaluation Rule
Count every live journey, integration, and approval gate before quoting, and price the maintenance obligation rather than the platform seat.

Frequently Asked Questions
Answers about pricing, setup, implementation, and more
Knock orchestrates lifecycle and transactional messaging across email, SMS, push, in-app, and chat by accepting natural language prompts to AI agents (Claude, ChatGPT, Cursor, Grok) and building workflows without code. Agencies use Knock to manage client onboarding flows, feature announcements, and triggered automations in a single platform. Performance is tracked across all channels in unified analytics.
Knock lists 2 plans; the paid price is $250 a month (Starter).
Partial white-label: the Starter plan ($250/mo) includes Knock branding removal from client-facing dashboards. Enterprise plans add per-customer branding and custom roles, enabling full multi-tenant white-label operations. Client-facing message content (emails, SMS, in-app) uses your brand, not Knock's.
Yes. Knock has native integrations with Claude, Claude Code, ChatGPT, Cursor, and Grok. You can prompt any of these agents directly within workflow steps to generate personalized message content per recipient. Slack MCP is also supported for workflow notifications.
Initial setup typically takes 30-60 minutes per client account once your agency parent account is configured. This includes connecting email and SMS providers, building the first workflow from a prompt, and testing message delivery. Subsequent workflows can be built in 10-15 minutes using the agent-driven builder.
Product-led SaaS companies (onboarding flows, feature announcements, usage-based messaging), e-commerce stores (order confirmations, abandoned cart recovery, promotional broadcasts), and agencies managing client messaging journeys. Any client sending lifecycle or transactional messages across multiple channels benefits from Knock's unified orchestration.
Yes. The Starter plan supports up to 2.5K guide active users and 50K messages per month. Enterprise plans add custom roles and per-customer branding, enabling agencies to manage multiple client accounts with separate billing, permissions, and brand settings within a single Knock workspace.
Knock does not publish explicit data export or retention policies in the available content. Contact Knock sales to confirm data ownership, export formats, and retention timelines before signing client contracts.
