What our customers are saying

We've been using Courier for over a year now, and it's probably saved us more pain (and time!) than any other single platform that we use. The product is getting better all the time and the team is incredible!
Neal Jean
CEO, Beacons
We are big fans of Courier. We use it to send all of our notifications. The platform is extremely easy to use and the customer support from the Courier team is supreme. I strongly recommend it!
Al Yang
CEO, Safebase
We love Courier. We rely on it heavily to send various communications. The designer is a fantastic tool. With it, we are able to get our UX designers working directly on the templates and we can make updates and have them live in seconds.
