• Implement personalization and behavioral triggers to increase relevance and performance.
• Lead A/B testing across subject lines, messaging, CTAs, and cadence to continuously improve results.
• Collaborate closely with Marketing Operations on segmentation, list building, scheduling, and technical deployment of emails within HubSpot.
• Ensure data accuracy, deliverability best practices, and database health in partnership with Marketing Operations.
• Define scalable processes, documentation, and governance standards to support consistent, repeatable execution.
• Establish KPIs tied to engagement, conversion, and pipeline contribution, and analyze performance to identify optimization opportunities.
• Continuously refine lifecycle programs to improve conversion, engagement, and overall revenue impact.
