Iterable

Iterable is an AI-powered cross-channel customer engagement platform for real-time email, SMS, push, and in-app messaging at enterprise scale.

What is Iterable?

Iterable is built for marketers running real-time, data-rich campaigns across multiple channels. Its journey builder, audience segmentation, and AI optimization features are genuinely advanced, which explains the strong TrustRadius score of 8.4/10. The trade-offs are also real: pricing is opaque, setup is engineering-heavy, and total cost scales aggressively with contacts and channels. It fits best in mid-market-to-enterprise teams that will use cross-channel depth; simpler messaging needs are better served by Customer.io or Klaviyo.
