How Customer.io wins

Multi-channel messaging

Orchestrate seamless campaigns across email, SMS, in-app, push, and webhooks within one platform, empowered with A/B and multivariate testing capabilities—something Iterable lacks, limiting your performance measurement options.

Data-first approach to messaging

Designed for marketers, Customer.io excels as a data-first platform, effortlessly activating your data with advanced features like custom objects, webhook-triggered campaigns, and anonymous tracking. In contrast, Iterable’s rigid approach enforces strict data types, posing challenges in managing messy data. Additionally, Iterable lacks flexibility in creating custom objects and upcharges and limits data, hindering your messaging strategy.

Automate and track the entire customer journey

Strategically distinguishing leads from customers for targeted messaging and relevant calls to action. Utilize multiple identifiers and anonymous IDs to seamlessly merge profiles as leads transition to customers. Iterable lacks the capability of allowing users to be part of multiple journeys concurrently without interruption to other journeys once conditions are met—a flexibility Customer.io provides seamlessly.

Illustration of a Customer.io workflow

It’s crucial for our team to make onboarding as fast and painless as possible because teachers are super busy. Customer.io allows us to segment new signups based on their remaining action items and send our teachers finely tailored guidance based on their real-time status.

Brendan Appold, Director of Classroom Success at Motion Math

With the flexibility and interoperability of Customer.io, we’ve been able to build some truly insane and elaborate onboarding flows. We’re sending webhooks, moving people down different paths, A/B testing, adding dynamic content with liquid, and automatically segmenting based on where the user came from.

Ammon Brown, VP of Growth at x.ai

Messaging frequency is key for our strategy. We can’t email our customers daily, so increasing frequency with a multi-channel strategy is how we can scale message volume. The conversion rates prove that strategy is working.
