Iterable Surpasses One Trillion Customer Interactions as Global Momentum Accelerates

Iterable, the AI customer engagement platform, today announced that it has surpassed one trillion customer interactions, reinforcing its status as one of the fastest-growing platforms in the enterprise marketing ecosystem. The milestone follows a year of impressive company momentum, including the appointment of new executive leadership, record-setting AI product innovation, and continued global expansion.

CMOs today face immense pressure to deliver efficient growth, orchestrate personalization at scale, and adopt AI safely and responsibly across their tech stack–often with leaner teams and tighter resources than ever before. Many are now reevaluating whether their legacy marketing technology can keep pace with these demands.

This is precisely the environment Iterable was built for. As an AI customer engagement platform, Iterable equips marketing leaders with the speed, agility, governance, and cross-channel intelligence needed to drive revenue, safeguard brand integrity, and simplify operational complexity. Today, more than 1,200 global brands rely on Iterable as the backbone of their most critical customer engagement programs, and to accelerate growth with confidence.

“A trillion interactions is more than a milestone—it’s validation of our momentum,” said Sam Allen, CEO of Iterable. “Enterprises are leaning into an AI-powered future, and Iterable has become the partner and platform they trust to transform their customer engagement. With Iterable, our customers are operating with unprecedented efficiency, sharper intelligence, and personalization at incredible scale. Our trajectory is strong, and I’m excited for what’s next.”

A Breakout Year of Global Momentum

Crossing the one-trillion threshold highlights the extraordinary scale of the Iterable platform, and clearly demonstrates its ability to transform massive volumes of data into intelligent, orchestrated customer experiences at a level unmatched across the customer engagement landscape. Surpassing this milestone caps a period of exceptional growth across the business:

• New Leadership to Drive Iterable’s Next Chapter: To support its accelerating global growth, Iterable has expanded its executive team with a series of strategic leadership appointments. Sam Allen joined as CEO this past summer from Salesforce, bringing deep enterprise expertise and operational rigor to propel the company’s next phase of growth. Priya Gill joined as Chief Marketing Officer this November, leveraging her experience as a two-time Iterable customer and seasoned global marketing leader to elevate the brand, modernize the go-to-market strategy, and ignite customer-centric growth. Nick Beil also joined in November as Chief Product Officer, and brings extensive experience in AI-driven analytics and product innovation to drive product strategy, advance the roadmap for Iterable Nova—the foundation of Iterable’s AI intelligence suite—and strengthen key technology partnerships.
  
  
  
  
• Record-Setting Peak Season Performance: Iterable delivered its strongest Black Friday performance to date, powering massive surges in early-season engagement — including a 30% year-over-year increase in pre–Black Friday volume — and a 10% rise in triggered messaging throughout the holiday shopping weekend. Cross-channel engagement hit record highs as brands paired email with mobile channels — with SMS alone growing 60% year over year — and engagement on those messages soared by 120%. Even under this intense load, Iterable maintained industry-leading deliverability and millisecond-level decisioning, underscoring the platform’s resilience, elasticity, and readiness for the most demanding enterprise moments.
  
  
  
  
• AI Breakthroughs and Record-Setting Enterprise Adoption: Iterable accelerated its AI investments throughout 2025, enhancing its AI intelligence suite with the launch of Iterable Nova and introducing the Model Context Protocol (MCP) Server — a new access layer that allows developers and technical marketers to connect specialized AI tools directly into Iterable and convert natural-language inputs into secure, governed platform actions.
  
  
  
  This innovation has fueled unprecedented customer adoption of Iterable AI. More than 90% of Iterable customers now use AI agents in their daily workflows, applying intelligence to decisioning, content creation, experimentation, and real-time orchestration. Customers are seeing measurable impact — 44% gains in conversions, 60% boosts in new customer revenue, and up to 70% lifts in active users — as AI becomes central to driving revenue growth, optimizing lifecycle engagement, and coordinating complex cross-channel programs.
  
  
  
  
• Enterprise-Grade Scale and Governance: This year, Iterable delivered 99.9% uptime with customer-level isolation, ensuring consistent performance and minimal disruption for global brands. As enterprises increasingly rely on AI-driven engagement, this level of reliability is essential—supporting high-volume personalization, real-time decisioning, and peak-season traffic without compromising speed or stability.
  
  
  
  Iterable also strengthened its governance and control framework to help enterprises safely scale agentic AI. With built-in safeguards for compliance, auditability, access control, and brand integrity, teams can accelerate automation and innovation while maintaining the oversight and security required in highly regulated environments.
  
  
  
  
• Expanded Global Footprint and Operational Scale: Iterable’s global footprint continues to grow rapidly. The company’s Lisbon office, opened in September 2024, has already become a critical hub for engineering, product, and operations. The team is scaling international capabilities, accelerating regional response times, and supporting the platform’s growing global traffic volume. The office has already more than doubled in size, with continued expansion planned as its impact grows.

Together, these achievements position Iterable for its strongest chapter yet—driven by a future-ready leadership team, accelerated AI innovation, and a global platform built to scale with the world’s leading brands.
