Knock agent for Slack - Build, manage, and ship customer messaging from Slack

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

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!

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

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 🚀

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.

Love this idea. If conversations start in Slack anyway, it makes sense that campaign creation should happen there too.

Tag @Knock, describe what you want, it works in the background — the flow sounds clean. But lifecycle campaigns often need legal or compliance review before they go out. Is there an approval gate built in, or does the agent produce send-ready output that someone still has to manually review before it actually goes?
