Build a complete customer onboarding email sequence for the following:

Business: [name and what it does]
Product or service: [describe what the customer just bought or signed up for]
Customer type: [B2B / B2C / SaaS / e-commerce / service]
Onboarding goal: [what the customer needs to do/understand to get value quickly]
Time to value: [how long before they experience the first win]
Common activation failure points: [where new customers typically drop off]
Sequence length: [7 / 10 / 14 / 30 days]
Email platform: [Mailchimp / Klaviyo / ActiveCampaign / HubSpot / other]
Personalisation data available: [name / company / plan type / what they signed up for]

Deliver the complete sequence:

ONBOARDING STRATEGY:
- The critical first 7 days (what must happen for the customer to stay)
- Milestones to engineer in the onboarding window
- How to segment onboarding by customer type or plan
- Failure signals to watch for (triggers for intervention)

COMPLETE EMAIL SEQUENCE:
For each email provide:
- Day number and timing
- Subject line
- Preview text
- Full email body
- Primary CTA
- Secondary CTA (if applicable)
- What success looks like for this email (open / click / action)
- Trigger condition (time-based / behaviour-based)

SEQUENCE ARCHITECTURE:
- Day 0: Immediate welcome (within minutes of signup)
- Day 1: Getting started (the most important first action)
- Day 2-3: Quick win (help them see value fast)
- Day 4-5: Feature discovery (expand their usage)
- Day 7: Check-in and obstacle removal
- Day 10-14: Social proof and success stories
- Day 21: Habit formation and advanced usage
- Day 30: Success review and next step

BEHAVIOURAL TRIGGERS:
- If they complete action X: send this email
- If they have not completed action X by day 3: send this intervention
- If they log in but do not complete setup: trigger this

IN-APP OR SMS COMPLEMENTS:
- Which emails should have a companion notification
- SMS message copy (if applicable)

ONBOARDING METRICS:
- Activation rate definition and target
