Iterable

Iterable lets growth teams design and run complex customer journeys that span email, push, SMS, and in-app messages. The workflow builder shows your entire funnel visually, making it clear where users drop off and where to optimize. Real-time segmentation and behavioral triggers let you adapt campaigns on the fly as new data arrives.

It appeals to product-focused teams who value automation flexibility and want tools that their technical members can configure without constant marketing ops help. API-first architecture and detailed webhooks make it especially strong for companies running sophisticated data pipelines.
