Ostro, an AI-powered engagement platform trusted by more than half of the top 20 global pharmaceutical companies, announced the launch of Ostro Airmark. This first-of-its-kind solution turns static rep-triggered and other brand-based emails to healthcare professionals (HCPs) into responsive, compliant conversational AI, all without the HCP having to leave their inbox.

Email has long been a primary digital channel in life sciences, but as an engagement strategy, it remains stuck in the past, with most HCPs unable to complete an action, ask a question, or receive timely answers without shifting to an entirely different channel. This results in suboptimal engagement rates, missed opportunities for meaningful dialogue, and slow feedback loops that hinder content optimization and next-best-action targeting.

Ostro’s Airmark addresses the problem by embedding AI-powered intelligence into brand email engagement tactics, transforming them from one-way communications into intelligent, compliant conversations. There are no portals or logins; just PRC-approved content that responds to real HCP questions and requests in real-time.

Airmark’s key capabilities include:

• Interactive messaging: HCPs can reply directly within an email to request information and receive compliant, instant answers with full audit trails.
• Adaptive learning: Airmark continuously adapts to individual HCP interactions to deliver increasingly relevant messaging over time.
• CRM-ready data: Every interaction is captured and synced to the brand’s commercial stack, enabling sharper targeting and faster insights via integrations with key platforms like Veeva, Salesforce, and IQVIA.

“Pharma emails aren’t falling short because of the content. They’re falling short because there’s no way to engage,” said Chase Feiger, MD, co-founder and CEO of Ostro. “Airmark makes it possible for HCPs to ask a question, get an approved response, and take the next step—all without leaving their email. That’s how you make the channel truly useful.”

“Email remains the backbone of HCP communications, but traditional approaches leave too much potential on the table,” said Donna Murphy, Global CEO at Havas Health & Creative Networks. “Airmark represents a paradigm shift, finally giving life sciences companies the ability to create genuine, two-way dialogue within the channel HCPs actually use daily.”

Airmark operates within Ostro’s omnichannel ecosystem alongside Ostro Tailor, which powers PRC-approved micro-content on HCP websites. Together, these solutions create a closed-loop system that identifies HCP interests, re-engages via intelligent email follow-up, and captures real-time feedback for continuous optimization to drive high-value actions.

“Airmark continues to expand the Ostro platform by fostering deeper engagement with HCPs through innovative and dynamic approaches,” said Arpa Garay, CEO at Harp Healthcare Advisors, LLC and former Chief Marketing Officer at Merck & Chief Commercial Officer at Moderna. “The ability to deliver relevant, compliant information instantly within email means physicians can access relevant information faster, resulting in better patient care.”

“What impressed us most about Airmark is how it maintains regulatory compliance while delivering the kind of personalized experience HCPs have come to expect in every other industry,” said Stacy Stone, Executive Director of Omnichannel at Pacira Biosciences. “The real-time data capture and CRM integration means we can finally close the loop between email engagement and commercial outcomes.”

Ostro will be exhibiting at Fierce Pharma Week, September 8-11, 2025, and presenting two sessions: “How AI Powers the Future of Omnichannel Engagement” on Wednesday, 12:00 PM ET, and again at 2:50 PM ET with “How AI Will Change Pharmaceutical Email and SMS Forever.” Attendees can visit Booth #719 for live demonstrations.
