KEY DIFFERENTIATORS

How Customer.io wins

Multi-channel messaging

Orchestrate campaigns across email, SMS, in-app, push, and webhooks—all within one central platform. Perform robust A/B and multivariate testing. Iterable's limited multivariate testing capabilities can reduce the effectiveness of performance measurement.

Data-powered marketing

Unlock powerful features such as custom objects and webhook-triggered campaigns for unlimited data activation. Iterable imposes limits on event storage and doesn't offer custom objects, reducing flexibility in message automation.

Cost effective

Choose Customer.io for cost-effective marketing with unlimited data and flexible payment options. In addition to premium pricing, Iterable adds implementation fees and up-charges for API calls, additional attributes, data storage, and events.

With the flexibility and interoperability of Customer.io we’ve been able to build some truly insane and elaborate onboarding flows. If a colleague asks me if Customer.io can do something cool, no matter what they ask my immediate answer is always, “Yes. Yes it can.” I love always having the answers! 

Ammon Brown

VP of Growth at x.ai

Customer.io has been a critical part of our onboarding process since the very early days of Segment. From the 43-minute founder email, which has allowed us to stay in contact with everyone who signed up, to much more complex challenges today.
