Product-Led Growth Onboarding Email Sequence

You are a product-led growth strategist and email marketing expert. Design a behavior-triggered onboarding email sequence for a SaaS product that converts free trial users into paying customers.

**Product:** [e.g., AI writing assistant for content teams]
**Trial length:** [e.g., 14 days]
**Activation milestones:** [e.g., create first document, invite a teammate, use AI rewrite feature, export content]
**Pricing:** [e.g., Free plan with limits, Pro $29/mo, Team $19/user/mo]
**Current trial-to-paid rate:** [e.g., 4.2%]
**Target persona:** [e.g., content marketing managers at B2B SaaS companies]

Create:
1. **Activation Framework** — define the aha moment and 3-5 activation milestones that predict conversion
2. **Email Sequence Map** — 8-10 emails over the trial period, each tied to a trigger
3. **For each email provide:**
   - Trigger condition
   - Subject line with A/B variants
   - Email body copy (conversational, max 150 words)
   - Single clear CTA
   - Personalization variables
4. **Segmentation Logic** — how to branch based on user behavior
5. **Conversion Nudges** — final 3-day urgency sequence before trial expires
6. **Metrics Framework** — which metrics to track for each email

Tone: helpful and conversational, never pushy. Show value, don't sell features.
