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. While Iterable supports multivariate testing, its capabilities are more limited, which can impact the depth of performance insights.

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 does not support custom objects, which may reduce flexibility for complex automation.

Cost effective

Choose Customer.io for cost-effective marketing with unlimited data and flexible payment options. Iterable may include added costs such as implementation fees and additional charges for API calls, attributes, data storage, and events.

Preferred byproduct-led companies

Customer.io has grown and surpassed Zwift’s needs over the years. Their tireless commitment to agile improvements to the platform has helped us to drive engagement through personalized and timely communications with our community.

Jonathan Walton

CRM Manager at Zwift

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.
