I like that Knock keeps my notification workflows alongside my code and helps me manage them across development, staging, and production, so I don’t have to version notifications separately or keep going back to a dashboard. I especially like the Knock CLI and its integration with AI agents. I can keep workflows in a shared repository, have agents draft and push notifications for a feature, test them in development or staging, and promote them to production with the CLI. That means less manual effort and helps avoid wrong notifications or agents using the wrong context. Setup was pretty easy with the Knock skill and AI agents: I could use one prompt, create an API key, and create workflows with the CLI. Knock also solved the chaos of managing notifications manually and the delivery hurdles we had. I don’t have to think much about notification-related things because Knock handles them simply and easily. I find it a very polished product and a great tool for developers who manage things with code or infrastructure as code. Review collected by and hosted on G2.com.

I had some difficulty finding things in the dashboard at first, like where the channels and settings were, since settings are under the profile section. I think the basic dashboard navigation could be improved for users. Other than that, everything is fine. Review collected by and hosted on G2.com.

- It was easy to integrate from C# backend app through the Knock SDK

- We were able to integrate the deployment in our CI/CD Pipelines

- Payload overrides feature helped us to customize the recipients and

- Shared layouts helped us to manage 1 common template to around +15 workflows that we've developed

- Translations helped us to handle en_US and fr_CA locales

- Knock provides a pretty good abstraction for us and we've been in PROD since April 2026 without disruptions

- Knock is a great platform that has helped us to minimize implementation time and be able to send emails and inapp notifications, for now we have around +15 workflows and with the potential to use it in the whole corporation I don't have details about pricing in my current role, I'm playing the Tech Lead role and leading a team of 2 consultant developers. We've got a pretty good experience with the product and we were able to achieve our milestones for the notifications scope. Review collected by and hosted on G2.com.

- Built-in feature flags integration with platforms such as LaunchDarkly, we managed to do it through global variables and Liquidbase code Review collected by and hosted on G2.com.

I like that Knock is super robust and easy to use. Even though there's a slight learning curve, it's a fundamental and super helpful product. Setting it up wasn't that bad—I've dealt with similar systems before that were much tougher, but Knock made it pretty easy. They even have an MCP that makes things really quick. I also love that Knock has a super generous free tier, and I'm excited to do more with it. Review collected by and hosted on G2.com.

I'd love to see it expand the integrations that are currently there and bring a few more templates to the table, like email templates so people can build more flexible stuff out of the box. Review collected by and hosted on G2.com.

I love the ability to test in complete isolation and promote changes to production environments when ready. Holding secrets and variables per environment and integrating with services like Clerk for synchronizing users and organizations via Webhooks is fantastic. The AI chat is amazing for building out prototype workflows and iterating. Having Clerk as the central source for user and organization authentication, combined with webhooks connected straight to Knock, ensures that notifications are only sent when necessary, abstracting away complexities we'd have to build ourselves. Being able to build large workflows in a dev environment and see versioned changes made before committing them allows us to clearly understand the changes. Review collected by and hosted on G2.com.

Integrations with external mail servers like Mailjet are a bit of a black box; they're difficult to debug when they go wrong so surfacing more of that connection would be helpful. We had an issue spanning a month or so where emails were failing to send from Knock to Mailjet, which ended up being because of IP address blacklisting caused by another customer that we were unable to see or identify through the integration and took a considerable amount of back and forth between us, Knock and Mailjet to resolve.

I like how Knock empowers marketing to run their own campaigns with its features and allows engineers to contribute significantly to marketing workflows. The design system is a plus, with well-defined environments and workflows promoted easily between development, staging, and production with Git storage support. This setup makes collaboration more efficient, and leveraging their CLI or opening repositories in VS Code makes modifications simple. I appreciate the way Knock has resolved issues I had with other platforms, and the speed at which the team responds to bugs and feedback is impressive, often within minutes during business hours. Their customer service is phenomenal, prioritizing customer needs and communication. One of Knock’s standout features is the option to bring your own API keys for communication services like email and SMS, which is more flexible than being restricted to a specific platform's service. This scalability and modular approach is a game changer for my operations. Review collected by and hosted on G2.com.

Honestly, nothing. 11/10 service. I wanna use it for all my projects. Review collected by and hosted on G2.com.

I think the product is really easy to use, optimizing both for developers and non-developers. The MCPs and AI tooling are really nice because they enable me to build things fast, and the nontechnical team members can edit easily. I find the commit system well thought out because it helps prevent things from breaking and allows for multiple people to work together via branching. I really value their support, as I'm getting fast response times over Slack, which allows me to resolve most of my issues quickly. Review collected by and hosted on G2.com.

We've had transient slowdown issues and small bugs, which is of expected from a company moving very fast. We use our own custom CRM to send SMS, so I had to build the integration myself and it was slightly annoying. There are also minor inconsistencies with say how webhooks are signed (ie. outbound vs channel). None of these are major issues, just expected immaturity at this size.

I find Knock invaluable for centralizing and streamlining all our product notifications across multiple applications and environments, eliminating slow, error-prone processes of managing custom notification logic, templates, and delivery channels. I appreciate the clean, consistent, and well-documented APIs, which make integration seamless even without the SDK. The workflow builder is a fantastic feature, allowing us to visually manage notification workflows with steps, delays, batching, and conditional logic. This functionality saves a huge amount of engineering time and removes the necessity for a custom pipeline. Additionally, I value the excellent support provided by Knock, particularly the Slack support channel, where Jeff offers outstanding assistance. The initial setup of Knock was incredibly easy, facilitating a timely integration into our systems. Review collected by and hosted on G2.com.

The only concern I have is about the logging and debugging aspects of Knock. However, I haven't checked their latest releases, so it might have improved since then. Review collected by and hosted on G2.com.

I really like the scheduling feature; I like how it removes most of the complexities of running jobs on my backend and thinking about how to fully manage notification schedules. I like the other additional add-ons (like throttling), which is something I use a lot right now for my unique needs. It was nice talking to support and sharing ideas on how to set up the workflows that I use for schedules so that they tailor to my system's specific needs. It was fairly easy to set up and integrate with my backend, and I use this feature the most.

Another honorable mention is user preferences, another powerful feature! Review collected by and hosted on G2.com.

I don't think I have found the documentation the most useful in some cases. For example, when I was setting up/thinking about throttling on some of my workflows, the documentation didn't explain using and setting it up well enough in my opinion. I ended up having to reach out to support just to be sure I had set it up the right way. I don't think the AI model that is currently there answers my questions enough.

I also noticed that the API for setting user preferences doesn't merge preferences properly; instead of relying on the user's current preferences to merge with the update, it falls back to the default. I had to implement the merging on my backend to avoid all of this. Review collected by and hosted on G2.com.

Very developer and PM friendly (assuming your technical) compared to some product focused at marketers that are too complex to integrate, works with our existing email sender, easy to get started, and quick implementation, outstanding support from the Knock team via both email and Slack (and they fixed issues we ran into). Beyond just support, knowing that items that are important to your success are a priority on their roadmap makes me feel comfortable with a long-term relationship.

I was tasked with finding a solution that could help us manage email and push notifications, user preferences, and keep our templates/content our of the code base. It needed to be developer-friendly and easy to implement quickly, and Knock stood out for what we needed at the time. Our engineering team was happy with it compared to solutions some have used in the past.

As a PM, I love how much I can do myself without engineering changes. The different environments make it easy to test things.

API support is great, and with some help from Claude I have even been able to script some things I needed to do vs ask my engineering team.

Template and content management is good, and ite easy to build and modify workflows.

I use knock a lot to manage onboarding and engagement notification workflows, send broadcasts, etc. Review collected by and hosted on G2.com.

Product Documentation could be improved, though I have used Claude and ChatGPT with pretty good success to get past those gaps; otherwise, ask their customer service team or test things out.

We encountered some limitations with user preferences regarding commercial unsubscribe, and it would be beneficial to have a Knock preferences UI that we can direct people to from an email to help manage compliance.

Lack of dynamic audiences is a limitation that is in the roadmap.

I wish more integrations could bring in user properties, as I would love to import properties from our PostHog instance, not just events.

Sometimes I wish it could do a bit more on the marketing side - the longer I can hold off on ANOTHER system in our stack the better. Review collected by and hosted on G2.com.

I like how simple Knock has made quite a complex concept, and the canvas editor is brilliant. The new AI agent they've added builds workflows in seconds, which is great. The initial setup was very simple, and the shared Slack channel was great. The solutions team was on hand for any questions. Review collected by and hosted on G2.com.

Sometimes the environments get in the way, but it's equally a nice way to stage code pre-production. Review collected by and hosted on G2.com.
