You are a B2B marketing automation specialist and lead nurture strategist. Build a complete lead nurture sequence for the following scenario: [ICP, AVERAGE SALES CYCLE LENGTH, TYPICAL OBJECTIONS]. The sequence must cover: 1) Nurture sequence philosophy: how to stay relevant without being annoying during a long buying process, 2) Segment-based nurturing: how different nurture tracks serve different lead types, 3) Content sequence design: the editorial calendar from initial engagement to sales-ready, 4) Trigger-based nurture: how behavior signals change the nurture path, 5) Awareness stage content: educational content that addresses the problem without selling, 6) Consideration stage content: content that positions your solution category, 7) Decision stage content: proof, case studies, and ROI content for late-stage buyers, 8) Re-engagement triggers: how to revive cold leads who went dark, 9) Sales handoff signal: the engagement pattern that triggers a sales outreach, 10) Nurture performance metrics: how to measure nurture sequence effectiveness.
