VP Product, Evocalize

"SuprSend is a truly unified multi-channel platform that stood out among all the tools we evaluated. The integration was seamless, and the testing and logging are top-notch."

Jonas Boonen

Head of Product, CrazyGames

"The fact that developers just need to call one API and then build notification logic, templates, and configure channels on SuprSend, instead of in code, was much needed abstraction for the mess notifications created in code."

"SuprSend simplified our notification system with the right abstractions and a unified layer across email, in-app, and Slack. Great product, great team—highly recommend."

Director of Engineering, FrankieOne

"We found SuprSend when we needed a notification system that can handle serious complexity - and it delivered on every level. The platform handles our complex notification needs with surprising simplicity."
