🛍️ E-Commerce Strategy Pack — 30 Economics-First Prompts for DTC + Marketplace

Your E-Commerce Session — Economics-First Analysis

Unit Economics Read

Let me do the math:

Gross Margin:

• Revenue per order: $49
• Product cost: $11
• Fulfillment: $6
• Payment processing (~3%): $1.50
• Gross profit per order: $30.50 (62% gross margin)

Strong gross margin. This is what supplements should look like — 60%+ gives you room to work.

Contribution Margin on New Customer (first purchase):

• Gross profit: $30.50
• CAC at blended $28: -$28
• Contribution margin: +$2.50 per first order

Barely positive, but positive. You're not losing money on acquisition, which is table stakes.

LTV:CAC Ratio:

• 60-day LTV: $82 (you gave this number)
• CAC: $28
• LTV:CAC = 2.93:1 (just under sustainable threshold of 3:1)

This is the hidden issue. You're right at the margin. Your current $12K ad spend at 3.5x ROAS = $42K revenue from ads, roughly aligns with your $45K/mo. But when you scaled to $18K/mo spend at 2.4x ROAS, your math would have been:

• $18K spend × 2.4 ROAS = $43K revenue (barely more than at $12K!)
• CAC doubled (from $28 to ~$50)
• LTV:CAC collapsed to 1.6:1 — unsustainable

You didn't 'just run unprofitable ads' — you hit diminishing returns on your audience at current creative. Classic Meta scaling wall.

The Real Problem

You asked: 'how to scale to $100K/mo without breaking economics?'

The real problem: your LTV is thin. $82 LTV at 60 days with a 62% gross margin product means you're basically getting 1.1-1.2 orders per customer in 60 days. Scaling spend without fixing LTV will always hit a ceiling.

To get to $100K/mo sustainably, you need EITHER:

1. Higher LTV (so you can tolerate higher CAC when scaling)

2. Lower CAC (new channel or better creative that breaks through scaling wall)

3. Both (the actual answer for most businesses)

You cannot scale your way past this with more spend. You have to fix the math first.

Prompts Selected from Pack

From the 6 pack categories, you need:

• Category 2.3: Post-Purchase Email Sequence Architect (expand LTV from $82 toward $120+)
• Category 4.2: Meta Ad Creative Framework for Scaling Walls (break through the current audience saturation)
• Category 5.1: Subscription/Replenishment Pathway Design (supplements specifically — subscription rates 20-40% is achievable)

Specifically prompts 2.3 (Post-Purchase Email Flow), 4.2 (Creative Refresh + Audience Expansion), and 5.1 (Subscription Funnel Design).

The Work (Next 30 Days)

Week 1: LTV Expansion (the foundation)

Build out Klaviyo flows beyond welcome series:

Your welcome series is only ~15-25% of where email/SMS revenue comes from. The rest lives in:

1. Post-Purchase Flow (highest ROI, you're missing this)

- Email 1 (day 3 post-purchase): 'Starting your adaptogen routine — tips from the lab'

- Email 2 (day 10): 'Stacking your adaptogen for specific outcomes' — educational, cross-sell opportunity

- Email 3 (day 20): 'You should be feeling X by now — here's what to watch for' — expectation management drives retention

- Email 4 (day 28): 'Your bottle runs out in 2 days — order now + save 10%' (reorder trigger)

- Email 5 (day 35): 'Haven't restocked? Here's why people skip and what it costs' (win-back)

2. Browse Abandonment + Cart Abandonment (if not built):

- Browse: 3-email sequence over 48 hours

- Cart: 3-email sequence over 72 hours + SMS 1 hour after cart abandonment

3. VIP Flow: customers who've purchased 2+ times get early access to new products, bigger discount codes, personal check-in from founder.

Expected impact: This alone typically lifts email/SMS revenue from ~8-12% of total to 25-35% of total. For your $45K/mo that's $7-10K additional monthly revenue from existing customers — zero additional CAC.

Week 2: Subscription Pathway (supplements specific)

You're selling a daily-use supplement without a subscription option. This is leaving 20-40% of LTV on the table.

Specific offer to build:

• Subscribe & Save: 15% off + free shipping on 30-day auto-ship
• Pause or cancel anytime (important — many operators bury this and get chargebacks)
• Include in post-purchase flow: 'You'll finish this bottle in ~30 days. Want to never think about running out?' with one-click subscribe conversion

Benchmark: Supplements brands typically see 20-35% of customers opt into Subscribe & Save when offered. If 30% of your current customers (~90 customers total) convert: subscription MRR = 90 × $49 × 0.85 (after discount) = ~$3,750 baseline recurring. Over time this compounds — new acquisitions also feed subscription.

Week 3: Meta Creative + Audience Refresh

Your scaling wall at $12K spend isn't a spend problem — it's an audience saturation problem. Two levers:

Creative diversification (you have 2 ads; 1 working):

• 5 new creative variants testing different angles: problem-aware (focus/stress symptoms), solution-aware (why adaptogens), brand (founder story), social proof (customer testimonials), mechanism-aware (how the blend works)
• Run $50-100/day each for 7 days, kill under 2x ROAS, scale over 3x ROAS
• Goal: 2-3 new winning creatives to add to your current rotation

Audience expansion:

• Lookalikes: 3%, 5%, 7% based on 180-day purchasers (you probably have 1% LAL — expand)
• Broad (no targeting, Meta's algorithm) — often works better than LAL in 2026
• Interest stacking: pair wellness + productivity interests (your product spans both)

Week 4: Scaled Acquisition Test

With expanded audiences + new creative + higher LTV:

• Increase daily spend 25% (from $400/day to $500/day = $15K/mo)
• Target 3x ROAS maintained
• Measure MER (total revenue / total ad spend), not just ROAS (which iOS 14 makes unreliable)
• If MER holds at 2.5x+ after 14 days: scale again to $20K/mo spend

Metrics to Track

• MER (revenue ÷ total ad spend) — honest truth, 2.5x+ is sustainable
• Email/SMS revenue % (target: 30%+ within 60 days)
• 60-day LTV (target: $110+ within 60 days, driven by subscription + post-purchase flow)
• Repeat rate at 60 days (target: 25%+ within 60 days)
• Subscription % of orders (target: 20%+ within 60 days)

Specific Actions

This week:

• Build the 5-email Post-Purchase Flow in Klaviyo (2-3 hours of setup)
• Design Subscribe & Save offer on Shopify (subscription app if not already: Recharge, Ongoing Subscriptions, or Shopify native)
• Brief creator (or yourself) on 5 new creative variant scripts

Red Flags in Current Strategy

1. You tried to scale before LTV expansion. Classic mistake. If you'd simply spent $18K/mo at your current unit economics it would keep failing. Fix LTV first, then scale.

2. Klaviyo = 'have welcome series' is table stakes, not a marketing channel yet. Most operators at your stage leave 80% of email revenue on the table by stopping at welcome series.

3. No subscription on a daily-use supplement. Every month you don't have this costs you recurring revenue + higher LTV. This is the single fastest lever.

4. Amazon at 15% of revenue: useful, but Amazon customers don't build YOUR brand's email list and have worse repeat economics. Don't scale Amazon above 25-30% without thinking about brand equity impact.

5. No retention creative specifically targeted at lapsed customers. Win-back flow (day 60, day 90, day 120 since last purchase) typically produces 5-10% additional revenue with near-zero CAC.

Decision Points

Scale to $60K/mo when:

• Email/SMS revenue hits 25%+ of total
• 60-day LTV expands to $100+
• Subscription rate hits 20%+

Scale to $100K/mo when:

• LTV hits $130+ at 60 days
• LTV:CAC ratio sustains at 4:1+
• MER at current spend level is 2.8x+
• Creative pipeline is 3+ proven winning variants

Consider hiring a growth person when:

• You hit $80K-$100K/mo and are running 3+ acquisition channels
• Not before — solo operator at this stage will give a hire the wrong problems

Reconsider product strategy if:

• After 60 days of above work, 60-day repeat rate is still under 15% → product doesn't have inherent retention and won't scale sustainably regardless of marketing
• Subscription rate after 60 days is under 10% → people aren't treating it as a habit product

Key Takeaways

• You cannot scale ad spend past your LTV ceiling. $82 LTV + $28 CAC = 2.93:1 ratio. Any scaling without fixing LTV hits the wall you already hit.
• Build out post-purchase email flow this week. 5-email sequence. Typical impact: 15-25% lift in email revenue.
• Launch Subscribe & Save. Supplements see 20-40% subscription uptake. $3K+ MRR baseline from existing customer base alone.
• Creative refresh + audience expansion breaks the Meta scaling wall. 5 new variants, 3 audience expansions.
• Track MER, not just ROAS. iOS 14 broke Meta attribution at scale. Revenue / total ad spend is the honest metric.
• Target 30% email/SMS revenue, 25% repeat rate at 60 days, 20% subscription rate. Hit these, $100K/mo is sustainable.
• Amazon is rent. 15% is fine; 30%+ starts costing you brand equity and customer relationships.
• Decision points: LTV $130+ at 60 days, LTV:CAC 4:1+, MER 2.8x+ all needed before scaling to $100K/mo. Hit these, scale. Miss these, the wall will hit you again.
