Re-engage event participants from HubSpot with Gemini and email outreach

Event Alumni Re-engager: HubSpot → Gemini → Personalized Outreach

Who is this for? Event marketers and conference organizers who want to reactivate past attendees with AI-personalized emails at 3-5x ROI vs. cold leads.

What problem is this workflow solving? Alumni gold is untapped: - Past attendees convert 3-5x better - Manual segmentation takes hours - Generic emails get ignored

This auto-segments + personalizes outreach from HubSpot data.

What this workflow does

CRM → AI Alumni Machine: - Trigger: Manual (or schedule 8-12 weeks pre-event) - HubSpot Pull: Past eventregistration contacts - Smart Filter: Exclude current registrants - 3-Tier Segments: Champions (3+ events) / Returning (2) / One-timers (1) - Gemini Personalization: Unique copy per attendee - Email Send: Alumni-exclusive CTAs - Slack Summary: Campaign stats posted

Main workflow required. This is a sub-workflow triggered by [Event Registration with Auto-Enrichment](link)
