Easy to Get Started, Robust Enough to Scale Across Teams

It’s easy to get started with, yet robust enough to scale as our needs grow. It works really well across marketing, data, and tech teams, making it a solid fit for different workflows.

Powerful Cross-Channel Insights, but SMS Analytics Lag

I like the campaign-level reporting roll-up and central creative asset library. I can inspect individual channels separately and see their aggregated performance within a broader multi-channel campaign, which gives us complete visibility.

Breaks Down Data Silos, Though Tracking Setup Takes Work

I like Customer.io’s seamless cross-platform data ingestion and accessibility. I can pull in user attributes and event signals from external tools and see that data right away in a readable, non-technical interface.
