Today we're shipping Partials 2.0. Partials are pre-built components that can be used across templates to quickly create beautiful messages and ensure brand consistency across every message your team sends.

Here's what’s new:

  • Custom brand attributes. Define brand colors and attributes using vars.branding.* variables. Update your design system in one place and have changes propagate across all templates.
  • Schemas for partial inputs. Partials now support optional input schemas for field types, labels, descriptions, and required flags, so editors can move faster without breaking brand or content guidelines. Schemas are versioned with the partial, making it easy to manage changes over time.
  • JSON object support for partial inputs. Partials now accept JSON objects through markdown inputs. This enables passing complex data like objects and lists instead of only strings.
  • Isolated CSS styles. HTML partials now support isolated <style> tags that inject into the email <head> only when the partial is used. Styles are deduplicated and pollute your root stylesheet.
  • Improved discoverability in the visual editor. All partials are now visible directly in the block editor, with search support to quickly find components.
  • Configurable editor experience. Default blocks (buttons, text, images, etc.) can now be disabled at the account level, limiting editors to use partials to enforce brand consistency.

These improvements are available today for all Knock customers. Read the documentation to learn more about building reusable email components with partials.

Today we're releasing webhook-backed delivery statuses, enabling you to receive delivery status updates directly from your email and SMS providers via webhooks.

Previously, delivery status checks in Knock were only possible via a sophisticated polling mechanism. At high message volumes, this polling had the potential to run into API rate limits imposed by messaging providers. Now, with delivery status webhooks, providers push delivery status changes back to Knock via webhooks. This makes the system more reliable as a whole and not susceptible to rate limits.

With delivery status webhooks enabled for your channels, you can:

  • Track successful deliveries. See when messages are delivered to the recipient's mail server or carrier.
  • Monitor bounces. Get notified when emails bounce due to invalid recipients or domains.
  • Better debugging. Understand delivery issues in real-time to troubleshoot notification problems.

We currently support delivery status webhooks for the following providers:

To get started, configure the webhook endpoint in your provider's dashboard to point to Knock. Each provider has specific setup instructions in our documentation.

Delivery status webhooks are available today for all Knock customers. Read the documentation to learn more about setting up delivery status webhooks for your channels.

Production write access enables you to create and update content resources in any environment, without requiring promotion from development.

This feature is enabled by default for all new customers. If you're an existing customer, production write access is an opt-in setting. To enable production write access, navigate to the Permissions page under the Admin section of your account settings.

When you enable production write access in your account:

  1. All roles with edit permissions can edit resources in any environment. Owner, admin, and member roles can create and edit content resources (like workflows and guides) directly in production.

  2. The Production-only Member role becomes available. This role gives a user access to the production environment, and no others. It enables non-technical team members to work in production without touching any resources that are managed in development. Learn more about the Production-only Member role.

  3. Content resources can only be edited in the environment in which they were created. This means that any content resources you want to follow your environment lifecycle (create in development, promote to production) are only editable in development. For use cases that don't need the governance of environment promotion, you can create directly in production.

Production write access keeps production-critical resources (like high-volume transactional workflows) version controlled by the development environment, while enabling marketing and product teams to work in a simpler, production-only way for lifecycle journeys and product announcements.

Today we're releasing asset management, a centralized way to upload, host, and manage image files directly in Knock for use in your messaging templates.

With asset management, you can now:

  • Store assets directly in Knock. Upload and store images like logos, icons, and graphics in your Knock account without needing external hosting.
  • Reuse assets across templates. Browse and insert uploaded assets into any message template with a single click. No more copying and pasting URLs.
  • Centralized control. Assets live in one place and are referenced everywhere, so you can update visuals across messages without touching templates, making it easier to keep your brand assets consistent.

Currently, only image files are supported, including PNG, JPEG, GIF, and SVG. In the future, we may support additional asset types.

Asset management is available today for all Knock customers. Navigate to Content > Assets to upload and manage your assets, or read the documentation to learn more.

Today we're releasing API key management, giving you more control over how you authenticate with Knock.

Previously, each environment in Knock had a single public and secret API key pair. This meant all of your integrations shared the same credentials, which made it difficult to rotate keys or limit access for specific use cases.

With API key management, you can now:

  • Create multiple API keys. Generate as many public and secret key pairs as you need per environment, enabling you to use dedicated keys for different services, integrations, or team members.
  • Revoke keys instantly. If a key is compromised or no longer needed, you can revoke it directly from the dashboard without affecting your other integrations.
  • Better security practices. Rotate keys on your own schedule and scope credentials to specific parts of your infrastructure.

API key management is available today for all Knock customers. You can manage your API keys from the Settings > API keys page in the dashboard, or read the documentation to learn more.

Since we launched our CLI back in May 2023, teams have used it to work with their Knock-powered notifications in code and to programmatically manage their messaging infrastructure, making Knock an extension of their development workflow.

Today, we're thrilled to launch the 1.0 release of the CLI, with a whole host of new features and improvements to make working with Knock locally and in your CI/CD pipeline even easier.

With the 1.0 release of the CLI you can now:

  • Login to the CLI using your Knock account, without needing a service token via knock login
  • Initialize a central knock.json file for your project, and use that for all pull and push commands without specifying where your Knock directory is located
  • Work with all versioned resources in Knock (workflows, templates, guides, layouts, translations), commit and promote changes, list environments and channels, and much more
  • Create new resources directly without going to the Knock dashboard, or from our new template repository via knock workflow new

We've also included JSON schemas for all of your resource definitions, providing an editing assist and type hints in your IDE for you and your favorite coding agent like Cursor, Copilot, or Claude Code.

CLI 1.0 is also fully compatible with our new branching beta. Using the CLI you can create branches, push and pull changes on those branches, and merge changes from your branch back into main when complete.

If you're interested in trying out the 1.0 release of the CLI, you can get started by running npm install -g @knocklabs/cli or brew install knocklabs/tap/knock. You can also read the documentation to get started.

Today we're excited to announce the beta release of branching, a new way for developers to work together in Knock.

Previously, all changes to versioned content in Knock had to be made in your development environment. That meant if you had multiple developers using Knock, changes needed to be carefully coordinated.

With branching, each developer can make changes in an isolated branch. Once changes are complete, the branch can be safely merged back into the development environment.

Branch management is deeply integrated into our management API and CLI, allowing you to use branching as a part of your everyday developer workflow or automate branches with your CI/CD pipeline. In addition, branching makes it possible to use Knock in preview environments, like those used by Vercel or Netlify. That means your team can test notification workflows end to end alongside other feature changes.

Branching unlocks an even better developer workflow within Knock, and we're excited to make it available today to all customers. If you're interested in trying out branching, you can request access from the dashboard on the Settings > Branches page. You can learn more in our documentation.

Today we’re excited to announce the beta release of dynamic audiences.

Dynamic audiences are segments of users you can use to trigger workflows, target guides, or build broadcast lists. You can also use dynamic audiences in your workflow conditions and branches to check if a user is in an audience and route them accordingly.

Here are a few use cases you can power with dynamic audiences:

  • Target a guide announcing an enterprise plan feature to your enterprise admin audience
  • Trigger your new user onboarding workflow when a user enters your new signups audience
  • Send a re-engagement broadcast to your "has not logged in for 30 days" broadcast

Dynamic audiences run on the user data you already manage in Knock and are updated in real-time. We built dynamic audiences to be fast and ready to work at the scale of our largest customers.

As of today's release, our segmentation engine works with users and user properties. We'll be adding support for source events and object/tenant data next.

If you're interested in trying out dynamic audiences, let us know and we'll get you set up. You can learn more about dynamic audiences in our documentation.

Today we’re introducing custom domains for link and open tracking for all Knock customers.

This allow you to use domains you own—rather than an auto-generated URL like e1.knock.app—for all tracked links in your messages. Aligning your tracking domains with your sending domain reduces the likelihood of spam filters flagging your messages and increases trust from users who expect links to come from you, not a third party.

Custom domains support granular configuration per message type and per environment. That means you can set up specific domains for specific purposes, such as one domain for short SMS links and another for long-form email URLs.

Custom domains are available today for all Knock customers. You can find out more in our documentation.

We've made a number of improvements to reduce friction when working with recipients in the workflow and broadcast builder.

  1. Recipient always selected. When you open a workflow or broadcast, a recipient is now automatically selected so you can preview recipient data in your workflow.
  2. Object recipients. You can now toggle the recipient or actor field to “object” and select the object you want to use while building and previewing your workflow.
  3. Inline-identify from the recipient selector. You can now add a new user or object directly from the recipient selector, without needing to navigate away.
  4. Edit users and objects. A new “Edit” button lets you make changes to user or object properties without leaving the workflow builder.

These improvements also extend to the test runner, where you're now able to inline-identify and edit user data.

Fixes and improvements

  • 👀 [Dashboard] You can now view a diff of uncommitted changes that have been made to versioned resources in the "Changes" tab.
  • 🐛 [Dashboard] We fixed an issue where writing liquid within a JSON template would fail validation.
  • 🐛 [Notification engine] We now validate all chat channel data before processing a chat channel step. Missing data will now show an error.
  • 👀 [Notification engine] We now send a Knock specific User-Agent header for all webhook channel and outbound webhook requests.
  • 🐛 [Dashboard] We fixed an issue where request signing could not be set on reusable requests.
  • 🐛 [Dashboard] We fixed an issue where toggling preferences with conditions would fail via the dashboard.
  • 👀 [API] We now pass through the Slack retry-after ratelimit headers with all Slack requests.
