Streamlined Notifications with Ease

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. It's been the first platform we've used for nearly three years, and we've grown with it, thanks to the ease of setup and integration. The API is simple, and I appreciate the custom React components provided, making the developer's work much more seamless.

Developer-Friendly (and PM friendly), Easy Integration, and Outstanding Support

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.
