Quick Setup & Results

Although FCM offers a variety of messaging channels, leveraging those channels requires an extensive setup process that can increase the time it takes to see value from the platform. In contrast, our extensive documentation library, powerful SDKs, and dynamic integrations make it easy to start sending messages today and optimize as you go.


Advanced Analytics, Segmentation, & Messaging Automation

Our Data Tags and Outcomes features let you customize the user events and interactions you’d like to track, so you can automate, personalize, and measure the success of your campaigns in a meaningful way.

FCM restricts the number of events and parameters that can be used for analytics and does not support custom segmentation, which can make it difficult to tailor your messaging strategy without purchasing add ons.
