Agile team, they really take customer feedback to heart. For example, they were super quick to add an SDK kit for Apple’s ATT. Their technical support is also top-notch — super responsive and helpful. The product has evolved over the years into a multi-channel engagement platform, but I really like the fact that they started as an A/B testing solution. You can really tell that testing & analytics are core to their DNA.

Ease of setting up campaigns and messages. Multi-channel marketing capabilities. in-app popups out of the box!

We replaced our ESP with Leanplum as our business had shifted more and more to mobile. In addition to sending email, Leanplum powers our push notifications and in-app messages. With our ESP we couldn’t merge user profiles across mobile and web, and with Leanplum this comes out of the box. We also had issues with customer service - getting anything fixed with our old ESP required service upsells with professional services. Leanplum’s support, on the other hand, is top-notch. It’s a modern tool with self-service documentation and made easy to use.
