Amazon won't let you email your customers. That's costing you 80% of their lifetime value. Get a free custom email sequence built specifically for your supplement—yours to keep, no strings attached.
Every sale you make on Amazon is a customer relationship you'll never own. Here's what that's actually costing you.
When someone buys your supplement on Amazon, you get their money—but Amazon keeps everything else. Their name. Their email. Their purchase history. Their ability to be reminded when they're running low on your product.
Amazon's Terms of Service explicitly prohibit sellers from using customer information for marketing purposes. You cannot add Amazon customers to email lists, send promotional emails, or include marketing materials in packages. Amazon owns the customer relationship—you're essentially a supplier to their marketplace.
This creates a devastating math problem for supplement brands:
| Metric | Amazon Customer | DTC Customer (With Email) |
|---|---|---|
| First Purchase | $45 | $45 |
| Email Capture | Prohibited | 100% Owned |
| Replenishment Reminders | Cannot Send | Automated |
| Cross-Sell Campaigns | Cannot Send | Automated |
| Average Repeat Purchases (12mo) | 1.2x | 4.8x |
| Customer Lifetime Value | $54 | $216 |
The difference isn't marginal—it's 4x customer lifetime value when you can communicate directly with buyers through email sequences designed for supplement purchase cycles.
This is why supplement brands averaging $50K–$500K/month on Amazon often have zero owned customer data despite thousands of sales. Every transaction happens in Amazon's ecosystem, and when the sale is complete, that customer disappears back into Amazon's marketplace—likely to be shown competitor products on their next visit.
The Platform Risk
If Amazon suspended your account tomorrow, how many of your customers could you contact directly? For most Amazon-dependent supplement brands, that number is zero. Email sequences built on owned DTC infrastructure solve this—every customer becomes a recoverable asset.
These seven automated email sequences form the foundation of supplement retention marketing. Each one serves a specific purpose in maximizing customer lifetime value—and none of them are possible when you're selling exclusively through Amazon.
Introduces your brand story, sets usage expectations, and builds trust before the product even arrives. Typically 3–5 emails over the first 7 days. This sequence has the highest open rates of any automation—often 50–70%—because customers actively want to hear from you.
Teaches proper usage, optimal timing, and what results to expect. For supplements, this is critical—customers who understand how to use your product correctly are far more likely to experience benefits and reorder. Reduces refund requests and negative reviews.
Timed to your product's usage cycle (30, 60, or 90 days), these emails arrive just as customers are running low. Simple, direct, and incredibly effective. Brands with proper replenishment sequences see 40–60% higher repeat purchase rates than those without.
Recommends complementary products based on what they've already purchased. Bought a probiotic? They might benefit from digestive enzymes. This sequence expands average order value and introduces customers to your full product line.
Re-engages customers who haven't purchased in 90+ days. Often includes a special offer or reminder of benefits they're missing. Win-back sequences can recover 5–15% of lapsed customers—revenue that would otherwise be permanently lost.
Rewards your best customers with early access, exclusive offers, and recognition. These high-value buyers deserve different treatment than first-time purchasers. VIP programs increase purchase frequency and create brand advocates who refer others.
Timed after customers have had enough time to experience results, these emails request reviews and offer referral incentives. Social proof drives new customer acquisition while referrals bring in pre-qualified buyers who trust their friend's recommendation.
The Compound Effect
Each sequence works independently, but together they create a system where customers receive the right message at the right time throughout their entire lifecycle. This is how email marketing generates $36–$45 for every $1 spent—compounding returns from automated communications that run 24/7.
Most email marketing agencies have never written a single FDA-compliant supplement email. They'll happily build your sequences using the same templates they use for fashion brands or software companies—and leave you exposed to regulatory action.
Supplement email marketing requires specialized compliance knowledge:
Structure/Function Claims vs. Disease Claims: You can say your product "supports immune function" (structure/function claim), but you cannot say it "prevents colds" (disease claim). This distinction applies to every email you send, every subject line you write, and every testimonial you share.
Required Disclaimers: Product-related emails must include the FDA disclaimer: "These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease." Placement and visibility matter.
Prohibited Content: Before/after photos implying disease treatment, comparisons to prescription drugs, claims about treating specific conditions (even in testimonials), and any language suggesting your supplement can cure, treat, or prevent illness.
ESP Platform Policies Add Another Layer
Klaviyo, Mailchimp, and other email service providers have their own policies for supplement brands. Some restrict certain categories entirely. Others require additional verification. Building sequences without understanding these platform-specific rules can result in account suspension and lost customer lists.
Every email sequence we build undergoes compliance review before deployment. We don't guess at FDA requirements—we know them because supplement marketing is all we do.

Supplement brands need 7 core email sequences: Welcome/Onboarding (introduces your brand and sets expectations), Post-Purchase Education (teaches proper usage and builds trust), Replenishment Reminders (timed to your product's usage cycle), Cross-Sell/Upsell (recommends complementary products), Win-Back Campaigns (re-engages lapsed customers), VIP/Loyalty Sequences (rewards repeat buyers), and Review/Referral Requests (generates social proof and word-of-mouth).
FDA compliance in supplement email marketing requires avoiding disease claims (cannot claim to diagnose, treat, cure, or prevent any disease), including the FDA disclaimer on product-related emails, using only structure/function claims with proper substantiation, avoiding before/after transformation imagery, and never comparing products to prescription drugs. Every email we create undergoes compliance review before deployment.
Email marketing for supplement brands typically generates $36–$45 for every $1 spent when properly implemented. This high ROI comes from email's ability to drive repeat purchases through replenishment reminders and cross-sells—revenue streams that Amazon-dependent brands miss entirely because they cannot email their customers directly.
No. Amazon restricts sellers from emailing customers for marketing purposes—you can only send order-related communications through Amazon's system. This is precisely why building a DTC channel with owned email infrastructure is critical. Your DTC customers can receive the full suite of marketing emails that drive repeat purchases and lifetime value.
Klaviyo is the leading ESP for supplement brands due to its deep Shopify integration, advanced segmentation capabilities, and pre-built flows designed for e-commerce. Alternatives include Omnisend and Drip. The key is choosing a platform that supports behavioral triggers, purchase-based segmentation, and predictive analytics for replenishment timing.
Welcome sequences show immediate results as soon as you begin capturing emails. Post-purchase and replenishment sequences typically show measurable revenue impact within 30–60 days, depending on your product's purchase cycle. Win-back campaigns for lapsed customers can generate revenue within 7–14 days of deployment. Full email program maturity—where all 7 sequences are optimized and contributing—typically takes 90 days.
Amazon's Terms of Service prohibit sellers from using customer information for marketing purposes. You cannot add Amazon customers to email lists, send promotional emails, or include marketing materials in packages. Amazon owns the customer relationship—you're essentially a supplier. This policy is why supplement brands averaging $50K–$500K/month on Amazon often have zero owned customer data despite thousands of sales.
