"We're able to focus on driving adoption of new features"
We knew that enabling our product and marketing teams to message users in the product would lead to more engagement and higher retention. Knock was exactly what we were looking for.

"Double the engagement while cutting costs"
One of the biggest things for me with Knock was the ability to change workflow logic without needing a developer. Before Knock, we saw users coming to the website about three times a week. After Knock, it was almost every day.
Tessa Kilbride
Senior Product Manager • Nellis Auction
"Easy access for our non-technical team"
The level of visibility Knock provides into our notification system was a game-changer. Our customer service team can now easily access the entire history of a notification, from the initial template to the final delivered message.

"Doubled our course completion rates"
From a product management perspective, I was most interested in getting the impact as fast as possible. It took longer to justify the buy decision than it did to implement Knock.
