## Overview
Webinar follow-ups are usually one generic email to a list. This Zap uses attendee data + their Q&A questions + engagement timestamps to write a short, warm, personalized follow-up email per attendee — grounded in what they actually cared about. Reply rates in tested deployments 3-5x generic sends.

## How it works
1. Trigger: new attendee row in a Google Sheet exported from Zoom/Riverside.
2. Fetch their question(s) and engagement peak (already in the sheet).
3. GPT-4o-mini drafts a 90-word email referencing their question by content, not just topic.
4. Zap creates a draft in Gmail / Hubspot sequence step.

## Benefits
- Every attendee feels the follow-up was written for them.
- Reply and meeting-booked rates rise dramatically.
- Sales team doesn't type — they approve.

## Use cases
- SaaS teams running weekly product webinars.
- Consultants using webinars as top-of-funnel.
- Community managers with high-engagement events.

## Step-by-step
### Step 1: Export attendee data
Name, company, question asked (text), engagement peak (topic + timestamp). One row per attendee.

### Step 2: Voice guide + rules
Warm, brief, ends with a soft ask (reply, book time). Never mention the tool used to write it.

### Step 3: GPT-4o-mini prompt
System: 'You are drafting a follow-up on behalf of {host}. Reference the attendee's actual question. Keep under 90 words.'

### Step 4: Route to Gmail/HubSpot
Create draft, not send — SDR reviews before sending. Or push into a Sequence with the personalized first-step body.

### Step 5: Measure vs generic control
Send 20% to a control with the generic template. Compare reply rate over 14 days.

## Example
```
Draft: 'Hi Priya — you asked how the pricing scales past 50 users. Here's the exact breakpoint chart I mentioned — screenshot attached. If you want to walk through it with your team, I've got 15 min tomorrow.'
```

## FAQs
**Can I skip Zoom and use Riverside/Streamyard?**

Yes — the input is a spreadsheet. Any platform that exports attendee data works.

**How do I capture engagement peaks?**

Zoom polls or a manual host-noted timestamp column. Even 'topic they reacted most to' beats nothing.

**Cost?**

About $0.001 per attendee. For 100 attendees per webinar, $0.10 total.
