The brief, the audience, and the two-track approach

The brand had strong product credentials — patented ingredient at the published clinical dose, liquid format with ~95% absorption — but no systematic content strategy, no email flows beyond a basic transactional welcome, and no retention infrastructure.

Two-Track Engagement

Content strategy and email automation were built in parallel — each informed by the same buyer persona and brand voice framework.

📝 Content Track

  • Brand voice + persona research
  • 30-topic content plan
  • Weekly calendar + platform mix
  • Social production — carousels, Reels, Stories

⚙️ Automation Track

  • 38 emails · 8 sequences
  • Full lifecycle from purchase to referral
  • SMS checkpoint automations
  • Retargeting · churn save · win-back

💡 The Audience Insight

The primary buyer responds to evidence — not aspiration. Every piece of content and every email was designed around this: provide the right clinical information at the exact moment she needs it, and let the data close the sale.

Brand voice · 30-topic plan · weekly calendar · multi-platform distribution

Brand Voice Framework

Guiding principle: confident, science-backed, and quietly bold — like a knowledgeable friend who has done their research and is not afraid to call out the industry for cutting corners.

30-Topic Monthly Plan — Four-Week Funnel Arc

Funnel ratio: 7 pain · 7 solutions · 8 expertise · 8 conversion. Most brands invert this and wonder why their sell posts underperform.

W1

Pains & Problems — Audience sees themselves

"You've been taking collagen for 3 months. Your skin looks exactly the same."

W2

Solutions & Social Proof — Show what changes, with specifics

"She'd tried four brands. Week 6 on ours, her dermatologist noticed the difference."

W3

Expertise & Breakdowns — Build clinical authority

"Not all marine collagen is the patented peptide. Here's why that matters clinically."

W4

Warm-up & Selling — Evidence-based close

"30 days. If you don't see a measurable difference, we'll refund you — no forms."

Instagram carousel · Reels scripts · Stories sequence

38 emails · 8 sequences · full lifecycle from purchase to referral

Built around one core insight: Persona 1 drops out at week 3 and advocates at week 8. Everything in between is designed to get her from one to the other.

Subject lines, timing logic, and why each email does what it does

The onboarding sequence spans 60 days across 9 emails. Its primary function is not selling — it is preventing the 67% week-3 dropout that characterises the supplement category.

⚡ E5 (Anti-churn, Day 21) — Most Commercially Important Email

E5 intercepts the 67% dropout window using the customer's own poll data as the hook, and routes replies into 3 personalised save branches: Path A (no difference → diagnose dosing), Path B (expected sooner → correct timeline, offer 2 free weeks), Path C (wrong product → symptom check, swap at no charge). Cost of 2-week extension: ~AUD $30. LTV of retained subscriber: AUD $1,140/year. Path B extension offer converts ~35% of replies back to active protocol.

Anti-churn branch rules · global suppression conditions

E5 Anti-Churn Branch Logic

All E5 replies are flagged for human review within 4 hours and routed into one of three branches. This is the highest-conversion intervention in the system.

Path A

No Difference

Diagnose: dosing consistent? Cortisol load high? Send Branch A email. 48h no reply → week 4 preview.

Diagnose first
Path B

Expected Sooner

Acknowledge expectation gap. Correct timeline with clinical data. Offer 2 free weeks if they continue.

~35% convert back
Path C

Wrong Product

3 symptom questions to confirm product fit. Swap at no charge → triggers new E1 tagged 'product-swap'.

New E1 day 0
LTV math: Cost of 2-week extension ~AUD $30. LTV of retained subscriber: AUD $1,140/year. Extension offer converts ~35% of Path B replies back to active protocol.
