About Iterable
Iterable is a cross-channel marketing automation platform founded in 2013 in San Francisco by Justin Zhu and Andrew Boni. The company has raised over $342 million in venture capital, including a $200 million Series E in 2021 that valued the company at $2 billion. As of April 2026, Iterable serves growth-stage and enterprise companies including Priceline, DoorDash, Calm, and Box.
The platform orchestrates customer communication across email, SMS, push notifications, in-app messaging, and web push through a unified workflow studio. Iterable's Workflow Studio provides a visual canvas for building multi-channel journeys with conditional logic, A/B testing, time delays, and channel-specific actions. A key differentiator is the ability to coordinate messages across channels within a single workflow: send an email, wait 24 hours, check if the user opened it, and send a push notification as a follow-up if not. AI-powered send-time optimization analyzes each user's engagement patterns to deliver messages at the time they are most likely to open.
Iterable uses custom pricing based on volume and feature requirements. Published pricing is not available on the website; prospective customers must contact sales for a quote. Industry estimates suggest pricing starts at approximately $500-$1,000/month for smaller implementations and scales to $10,000+/month for enterprise deployments with large contact databases and high messaging volumes. The platform includes a Brand Affinity scoring system that uses AI to classify users as loyal, positive, neutral, or negative based on engagement patterns.
Iterable integrates with Segment (customer data), Amplitude and Mixpanel (analytics), Salesforce and HubSpot (CRM), Snowflake and BigQuery (data warehouse), Shopify (ecommerce), and supports custom integrations via REST API and webhooks. Catalog and event-driven personalization enable dynamic content based on real-time user behavior.
