Knock is a product and customer messaging infrastructure. You can use Knock to power all of your product's messaging needs, including transactional messaging, lifecycle marketing, one-time announcements, and in-product messaging, without the effort of building and maintaining your own in-house messaging system.
Knock is made with engineering, product, growth, and operations teams in mind. It's easy for developers to implement, and simple for less-technical users to maintain in our dashboard.
This is the 5th launch from Knock. View more
Knock agent for Slack
Launching today
Knock is the agent-led customer engagement platform for managing all the messages your users receive across channels.
After connecting Knock to Slack, simply tag @Knock in any channel, describe what you want, and let the agent work in the background to build campaigns, draft messaging, and update lifecycle workflows.
The agent gathers the context from your account, posts progress updates in the thread as it works, and provides a link to the resource when it's ready to review.

Hey Product Hunt — Chris from Knock here.
We built Knock agent for Slack because customer messaging work already starts in Slack: someone asks for a launch email, a lifecycle update, an audience change, or a campaign tweak, and then the actual work has to move somewhere else.
Now you can tag @Knock in Slack, describe what you need, and let the agent work in the background to build, edit, and manage your customer engagement resources.
It can help build campaigns, draft messages, update workflows, and answer questions about your messaging setup. Once it’s done, it provides a direct link to review any modified resources in Knock.
The important part: the agent gathers the context from your account—your workflows, audiences, layouts, styles, channels, and brand system—so the output is always on-brand.
We see this as a step toward agent-led customer engagement: less tool-switching, fewer repetitive edits, and faster movement from idea to shipped messaging.
Would love feedback from anyone building lifecycle, product, growth, or customer communication systems.
Knock on,
Chris Bell, CTO + Co-founder @ Knock

This launch is a special one. For a couple weeks now, I've been messaging Knock from Slack to build our May newsletter, update our onboarding campaign, draft in-app messages, and even create the broadcast for this launch.
It's as simple as a tag and a prompt...and I get a link back to review and publish.
If you’re excited about what we’re building, we’d appreciate your upvote. Try Knock today to see it in action 🚀
building campaigns by just tagging an agent in slack instead of switching to another dashboard is how more tools should work. the context is already in the conversation so why leave it

The team cooked on this one! We're excited for you all to try the Knock agent in Slack and to bring lifecycle messaging infrastructure to all the surfaces where you want to use it. Try it and let us know what you think!

This feels like a great example of AI removing busywork rather than creating more of it. Nice work by the team!

Huge congratulations to the Knock team! Reducing context switching is one of those improvements that sounds small but has a huge impact on productivity.
