TT Tyler T. Senior Web Developer Small-Business (50 or fewer emp.) 6/28/2026 "Robust Multichannel Notifications Made Easy" 5/5 What do you like best about Knock? 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. What do you dislike about Knock? 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. What problems is Knock solving and how is that benefiting you? I use Knock for multichannel notifications in my apps, allowing me to message and filter contacts efficiently. It provides connection pathways, Slack integration, and is super robust and easy to use.

Lead Engineer Mid-Market (51-1000 emp.) 5/11/2026 "Effortless Workflow Management with Powerful Integrations" 5/5 What do you like best about Knock? 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. What do you dislike about Knock? 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. Review collected by and hosted on G2.com. What problems is Knock solving and how is that benefiting you? Knock simplifies complex workflows, abstracts email design complexities, manages in-app notifications seamlessly, and integrates with Clerk for efficient user sync. It allows isolated testing, easy promotion of changes, and holds secrets and variables, enhancing workflow management. Review collected by and hosted on G2.com.

Core Contributor Small-Business (50 or fewer emp.) 4/6/2026 "Empowers Marketing and Engineering with OUTSTANDING Customer Support" 5/5 What do you like best about Knock? 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. What do you dislike about Knock? Honestly, nothing. 11/10 service. I wanna use it for all my projects. Review collected by and hosted on G2.com. What problems is Knock solving and how is that benefiting you?

Small-Business (50 or fewer emp.) 3/12/2026 "Easy to Use with Stellar Support but Needs More Maturity" 4.5/5 What do you like best about Knock? 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. What do you dislike about Knock? 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. Review collected by and hosted on G2.com. What problems is Knock solving and how is that benefiting you? Knock simplifies our all our workflows, making it easier for non-technical users to visualize and manage processes. The visual editors enhance email design, and it's much more manageable for non-developers. The AI integrations & MCP made the building workflows extremely fast. After moving to Knock, we've been able to ship new comms 2-3x faster than before. Review collected by and hosted on G2.com.

AM Abdelrhman Samir M. Software Engineer Small-Business (50 or fewer emp.) 12/27/2024 "Streamlined Notification Management with Superb Support" 5/5 What do you like best about Knock? 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. What do you dislike about Knock? 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. What problems is Knock solving and how is that benefiting you?

Software Engineer Small-Business (50 or fewer emp.) 11/22/2025 "Effortless Scheduling and Seamless Integration" 4.5/5 What do you like best about Knock? 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. What do you dislike about Knock? 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. What problems is Knock solving and how is that benefiting you? I think the main problem it is solving, and this is a broad enough problem, is that it removes a lot of complexities of notifications from my backend, managing user preferences, handling schedules, channels, etc. Review collected by and hosted on G2.com.

Director of Product Small-Business (50 or fewer emp.) 11/14/2025 "Developer-Friendly (and PM friendly), Easy Integration, and Outstanding Support" 4.5/5 What do you like best about Knock? 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. What do you dislike about Knock? 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. What problems is Knock solving and how is that benefiting you? We needed to do more to manage email and push notification workflows, from onboarding to progress/activity notifications, and some light marketing workflows/broadcasts. We are a small startup, so we needed something developer-friendly and light to implement and use. It lets us pull a lot of notification/email logic and content out of our code.

AN Andy N. 12/9/2025 "Effortless Notification Scheduling with Knock" 4.5/5 What do you like best about Knock? I like how easy it is to just have an endpoint we can call to schedule notifications. It's especially beneficial when dealing with notifications that need to be sent in the future. Within those workflows, it feels pretty easy. Review collected by and hosted on G2.com. What do you dislike about Knock? I think that I would like to be able to use codebase interface, maybe through the CLI. Handling a notification engine, we pretty much have to build that part of the infrastructure ourselves. I would like to have more of a condition-based event approach. Let's say that whenever an event happens, then look for other conditions to see if the user met that requirement so that we can build an identification engine. Right now, I don't know if it's possible to do. So that part of the infrastructure we built ourselves. Review collected by and hosted on G2.com.

Chief Product Officer Small-Business (50 or fewer emp.) 9/17/2025 "Absolutely the best notifications product, hands down." 5/5 What do you like best about Knock? Knock has been a boon for us. It’s easy to set up, powerful, and clearly built for both PMs and engineers. We started out manually coding every email in our SaaS app, but once we needed multi-channel support and more complex workflows, it became unmanageable. I randomly came across Knock on Twitter, checked out the demo, and with just me (a product lead) and one engineer, we had over 10 workflows running across email, SMS, and in-app within weeks. Review collected by and hosted on G2.com. What do you dislike about Knock? There is nothing I dislike. I would highly recommend this. Review collected by and hosted on G2.com. What problems is Knock solving and how is that benefiting you? We had a ton of requirements: supporting notification preferences within and across organizations; building dynamic templates with conditional logic; handling reminders, batching, attachments; and giving our support team visibility into delivery status. Knock supported every single one of these out of the box. Whenever a customer asks if their client received an email, the real-time audit trail makes it simple for non-engineers on our team to check - this has been a game changer for support. On top of that, the support from the Knock team has been phenomenal (Jeff is a rockstar), and even a non-technical college freshman intern on our team was able to learn Knock and build workflows in under a week. It’s rare to find a product that combines this much power with this much usability. I highly, highly recommend it to anyone. Review collected by and hosted on G2.com.
