Knock is a product and customer messaging infrastructure. You can use Knock to power all of your product's messaging needs, including transactional messaging, lifecycle marketing, one-time announcements, and in-product messaging, without the effort of building and maintaining your own in-house messaging system.
Knock is made with engineering, product, growth, and operations teams in mind. It's easy for developers to implement, and simple for less-technical users to maintain in our dashboard.
This is the 3rd launch from Knock. View more

Email API benchmarks
Launched this week
Today we're releasing email API benchmarks, a real-time dashboard of email provider performance to help you compare and choose.
The dashboard is powered by the billions of API requests Knock sends to downstream providers like SendGrid, Resend, Postmark, and more. We've aggregated this data to highlight important metrics (like response time and error rate) to help you compare email providers, not based on hype, but on their real-world performance data.

At this point we have a lot of data about how each email provider operates at a very high scale. We're thrilled to make this available to all so folks can make informed choices about the provider they should pick. All powered by our Clickhouse cluster.
