Senior Software Engineer Small-Business (50 or fewer emp.) 9/17/2025 "The best notifications platform we've used" 5/5 What do you like best about Knock? I lead the implementation of Knock in our stack, and it’s one of those rare tools that gets the balance right between being developer-friendly and marketing-team friendly. From an engineering perspective, my job is to simply wire up triggers and send data from our app. From there, our copywriters and marketers can own the templates without needing me in the loop. That separation of concerns has been a huge productivity boost. Knock has also gone far beyond just "send a notification." Features like schedules and delayed notifications mean we don’t have to waste time setting up cron jobs ourselves. The logging is excellent too, it’s easy to debug and see exactly what’s happening. The development workflow is one of the standout parts for me. Multiple environments, the ability to incrementally push changes, and even seeing commit diffs on workflows, it feels like Knock was built with real engineering teams in mind. Other highlights: - The free tier was more than generous enough to cover our POC. - Sandboxing notifications helps us avoid burning through third-party usage. - Support has been unreal, even from the other side of the world, questions in their Slack community get answered quickly. - The workflow builder is incredibly powerful, with branching, batching, conditions, and customisations that make it easy to design complex flows that were simply not possible when we were using a different product and we had to add a bunch of messy workarounds Ultimately, Knock is a tool that knows what it’s good at and does that really well. That’s exactly what I want as an engineer, and it’s exactly how I’d describe our experience with it. Review collected by and hosted on G2.com. What do you dislike about Knock? I would really like to be able to access the data for more than just 10 activities in my templates. Being able to edit delayed workflows instead of cancelling them and triggering them again would also be helpful. But that is splitting hairs. Review collected by and hosted on G2.com. What problems is Knock solving and how is that benefiting you? Knock solves the business problem of managing complex notifications without requiring us to build and maintain that infrastructure ourselves. It handles scheduling, batching, branching, and delays out of the box, which saves us significant engineering time and reduces the risk of errors in production. Having marketing own the templates directly means faster turnaround on copy changes without engineering becoming a bottleneck. Sandbox mode keeps costs down by protecting third-party usage during testing, and the strong logging and multi-environment support give us confidence as we move from staging to production. Overall, Knock lets us deliver reliable, timely notifications to our users while freeing up engineering resources to focus on core product work. Review collected by and hosted on G2.com.

We actually have support for accessing data for more than 10 activities in templates but we need to enable on our side. We've gone ahead and upped this limit to 100 for your account.

VB Vishesh B. Director Small-Business (50 or fewer emp.) 9/16/2025 "One of the best customer messaging platforms out there." 4/5 What do you like best about Knock? We've been using Knock since its early days, and it is one of the best infrastructure messaging tools out there. Its intuitive setup and seamless integrations make it incredibly easy to get our own tools up and running quickly. The documentation is comprehensive and easy to navigate, and the customer support team is outstanding—responsive, knowledgeable, and among the fastest we've encountered. Review collected by and hosted on G2.com. What do you dislike about Knock? One of our key feature requests is for ticketing integrations—as a customer‑facing company, this would help us avoid the constant cycle of building custom ticketing solutions, and let us define a ticket once and see it across all our apps. We’d also like more environment decoupling. Currently, promoting changes requires applying them in all environments, which becomes overly complex for heavy customisations and dedicated or on‑prem deployments. Review collected by and hosted on G2.com. What problems is Knock solving and how is that benefiting you? As an Identity Security & Access Governance company, many of our use cases revolve around access requests and user access reviews, including Just‑In‑Time (JIT) access workflows. Because of the real‑time nature of our business, Knock has been a major enabler since it abstracts away our notifications infrastructure so thoroughly that we can retire a lot of engineering and maintenance overhead and stay focused on what matters most—building our core platform.

RM Raphaël M. Head of Engineering Small-Business (50 or fewer emp.) 9/16/2025 "Notifications management made (very) easy" 5/5 What do you like best about Knock? Knock makes it easy for us to manage notifications. We primarily use it for Teams, Slack and emails, but its real value is that it decouples our notification system from our codebase. This gives our product team the power to move at their own pace, fixing bugs and improving notification models and messages without depending on engineering. Iterating is as simple as a click, which has significantly accelerated our ability to test, adjust, and improve the experience. Customer support has been excellent. They set up a dedicated Slack channel for us, and every time we had bugs or questions, we were able to talk directly with their team. Most of the time we got answers or fixes extremely quickly, which has been a great experience. Review collected by and hosted on G2.com. What do you dislike about Knock? The product can feel a bit complex at first because of the wide range of features and possibilities. There’s some trial and error involved in figuring out what you want to achieve and how to get there, which can feel a little overwhelming in the beginning. However, once you understand the logic and know your way around, it becomes very fast to use. Duplicating workflows, creating new ones, or adapting to the email templating language may take some initial effort, but once you get past that learning curve, it’s extremely powerful. The flexibility and depth of customization make it a tool that really pays off once you’re familiar with it. Review collected by and hosted on G2.com. What problems is Knock solving and how is that benefiting you? The real value of Knock for us is the ability to decouple notification management from our codebase and give product teams the autonomy to iterate at their own pace. They can test emails, respond to customers, and handle internationalization—which is a critical need for us—without relying on engineering. This setup allows us to move much faster, be more impactful in our communication, and stay focused on our core business: building our HR platform. Review collected by and hosted on G2.com.

The devrel team at Knock and the community space they've created is excellent and very responsive. The Audit logging features are the best of any developer integration I've ever used. Our ability to debug specific issues is unparalleled. Batching of notifications was the killer feature that brought me to Knock and it does enough of what I need to keep me very happy.

Sometimes the documentation on the SDKs is a little outdated or the examples incomplete so you HAVE to rely on the devrel team. Review collected by and hosted on G2.com. What problems is Knock solving and how is that benefiting you? Our product is heavy in transactional notifications, currently both web push and Slack/Teams. The volume is high enough that batching is absolutely required and while we did previously build our own primitive batching functionality, Knock handles it much better than we do and without billing penalties.

SC Stefan C. 1/21/2026 "Streamlined Multi-Channel Notifications with Knock" 5/5 What do you like best about Knock? I think the best feature of Knock is the observability. It allows us to drill down into the specifics of each notification for each user or channel. This level of detail is really, really useful especially when something goes wrong or a user reports not receiving notifications. Our support team can leverage this feature and solve issues pretty easily without the engineers having to dig deep into it.

I love using Knock for its excellent developer experience, making it easy for me to trigger Slack, Email, and in-app notifications. The simple and intuitive UI is greatly appreciated, especially for non-technical team members who manage what notifications look like. Knock offers a straightforward way to handle both notifications and workflows. Additionally, we find it valuable for managing announcements, such as new feature releases.

Senior Software Engineer Small-Business (50 or fewer emp.) 9/13/2025 "The best developer friendly platform to have notifications in your application" 5/5 What do you like best about Knock? Its very easy to use, very little learning curve. Implementation is straightforward just looking at the docs we got started in under 10 mins. Integrations with other platforms like AWS, Mailchimp, etc are there which is very good and the workflow is pretty easy to understand and use Review collected by and hosted on G2.com. What do you dislike about Knock? The templates and "general" outline template was not intuitive at first and sometime there are errors in workflow exection i.e. notification node failing due to 3rd party issues which are not there in the logs and not clear. Got it figured out through support but would have been better if its clearer from the start Review collected by and hosted on G2.com. What problems is Knock solving and how is that benefiting you? Knock addresses all in one kind of notification management integration platform for technical people to have in the applications very fast which is pretty awesome. I personally haven't encountered a application which does this so seamlessly so far. Review collected by and hosted on G2.com.

Knock is an engineering-first platform. Their API is robust, and they ship solid features at a steady pace. Review collected by and hosted on G2.com. What do you dislike about Knock? The only major downside to Knock is that the filtering and pagination in some of the observability views in the Knock dashboard can feel a bit limiting. At times, it’s hard to find exactly what I’m looking for. Review collected by and hosted on G2.com. What problems is Knock solving and how is that benefiting you? Knock is solving fan-out and last-mile delivery for us, which lets us focus more on the notification content and less on the plumbing needed to get all the different channel types working cohesively.
