6sense launched AI Email Agents — an evolution of Conversational Email — with persona-driven agents covering the full email lifecycle for pipeline creation, the company said on 28 August 2025.
The agents are described as writing, sending, following up, reading replies and routing qualified opportunities to sales. AI Email Personalization builds one-to-one messages from custom prompts, CRM data and proprietary Signalverse insights rather than first-name tokens alone. A new enterprise-grade native email provider is intended to improve deliverability and avoid third-party send limits. Custom Agent Hours and Handoff Logic let teams schedule weekend or off-hours work and route leads by role, region or other rules.
Ashley Deibert, chief marketing officer at Marigold, said: "With 6sense AI Email Agents, we've been able to scale personalized outreach, generate a 7x increase in pre-funnel conversion, and reduce our ad spend—without sacrificing quality." The release also referenced a redesigned Revenue Marketing homepage, segmentation and analytics upgrades, and The Trade Desk integrations for display, native and connected TV. Conversion and ad-spend outcomes are customer claims and have not been independently verified by AI-360.
