Notifizz and Knock

Messaging as infrastructure.Or campaigns wired to your data by AI.

Knock provides messaging infrastructure with developer tooling (API, CLI, environments, version control), a dashboard where product, marketing and growth teams build workflows, broadcasts and guides, and AI tools (an in-dashboard agent and an MCP server). Notifizz connects each campaign to the data in your own systems, with AI wiring the connections.

Consider Notifizz when

Shared campaign workflow.Data read from your systems.

You’d rather not import or sync recipient profiles into a messaging platform: campaigns read the customer data they need from your own systems.
You want AI to check each campaign against your events and data, and list only what engineering still has to implement.
You want marketing, product and engineering in one campaign workflow, with an implementation step and a review before your team publishes.
You prefer a European vendor, with the platform hosted in France by a French provider.

Consider Knock when

Their strengthsmatch your priorities.

You want messaging managed as code (CLI, branches, commits, CI/CD), alongside a dashboard for non-technical roles.
Slack, Microsoft Teams, Discord, WhatsApp or mobile push delivery is essential.
You want to bring your own email and SMS providers, with workflow versions promoted across environments.

A different starting point

Use your customer data.Where it already lives.

Profiles kept on the platform

Store. Sync. Maintain.

Your CRM and product data
Recipient profiles kept on the messaging platform
Campaigns use stored profiles and trigger data

Keep the platform’s profiles aligned with your own systems.

Knock stores every notified recipient, identified in advance or inline at trigger time; a fetch step can also call your API during a run.

The Notifizz approach

Connect. Read. Send.

Your CRM and product stay the source of truth
The campaign requests the context it needs
The published message is personalized and sent

No customer contact database to import or keep synchronized.

These diagrams compare data models. Notification delivery still involves operational records and retention; freshness also depends on the source and any configured cache.

Notifizz and Knock: data, workflow and delivery
What matters	Knock	Notifizz
Customer data	Recipient properties, preferences and channel data are stored.	No customer database to import or sync. Notifizz keeps only what sending requires (identifiers, addresses, preferences, delivery history); everything else is read from your systems when the message is built.
Channels	Email, SMS, mobile push, in-app feeds and guides, chat (Slack, Microsoft Teams, Discord, WhatsApp) and webhooks.	Email and Notification Center are available. Web push is in closed beta and Intercom in pilot; SMS and WhatsApp are coming soon.
Live personalization	Trigger payloads and stored recipient data, plus a fetch step that calls your HTTP endpoint during the workflow run.	Enrichers read your systems when the message is built, with a short cache: one hour by default, configurable per source.
Campaign creation	Workflows and in-app guides are built in a visual dashboard or as code, broadcasts in the dashboard, and an in-dashboard AI agent can build them too; engineering, product and growth teams share the work.	Marketing and product create in a shared workspace; engineering implements what is missing.
Developer work	Engineering integrates triggers and recipient data; workflows can then be edited in the dashboard or managed as code through the CLI.	Connect events and enrichers. Reuse existing requirements; implement the missing ones.
Review and versions	Workflow versions are committed and promoted across environments, with history, rollback and branches.	Editing, Implementation, Review and Live. Nothing goes Live until someone on your team publishes it. New campaigns go through Review first, and so do updates that change a campaign’s logic (event, steps, conditions, recipients, channels or data); text-only edits can be published directly.
Email delivery	Connect your own email provider, such as SendGrid or Postmark; delivery, bounce and engagement tracking depend on the provider.	Your own domain, a spam score on Review test sends, and delivery and bounce data from the provider.
Hosting and privacy	Recipient data is stored on the platform, hosted on AWS in the US according to Knock’s subprocessor list.	Hosted in the EU (France). US subprocessors: Cloudflare (network), Postmark (email delivery) and Anthropic (AI). The AI designs campaigns from the structure of your events, never their values; a test run you ask it to debug is shared with it. No contact database sync. Suppressed addresses are kept as keyed hashes.

The practicalquestions.

Talk to us

Can Notifizz replace Knock for our team?

Start with your required channels and workflow. Notifizz brings product and transactional campaigns together around live data and human review; marketing broadcasts are in closed beta. Knock may fit better where its channel coverage or its messaging-as-code approach is essential. A demo with your own use case makes the trade-offs concrete.

Can developers still keep control?

Yes. Developers connect events and live data, implement what is missing from their IDE, and test campaigns in Review. Marketing can reuse what is connected; a new event or data requirement still needs engineering.

What changes for our customer data?

Notifizz reads the data each message needs from your systems, so there is no second contact database to keep in sync. Like Knock, Notifizz acts as a processor. The platform is hosted in the EU (France); Cloudflare (network and security in front of our services), Postmark (email delivery) and Anthropic (AI campaign design) are US subprocessors. See the privacy policy for the scope of data processing.
