How a Supplement Brand Generates $600K+ Monthly from Email

The Challenge

This fast-growing health and wellness supplement brand had built a loyal customer base and a 180,000-subscriber email list. Their products—ranging from vitamins and protein powders to specialty wellness formulations—generated strong repeat purchase rates, and email was historically their most profitable marketing channel.

However, as they scaled their product line and increased email frequency to support new launches and promotions, they noticed a troubling trend: email revenue had plateaued at around $220K per month despite growing their list and increasing send volume. Customer acquisition costs were rising, but email wasn't converting at the rates they needed to hit growth targets.

With 29% of their emails never reaching inboxes and cart recovery sequences failing to deliver, they were leaving massive revenue on the table. Every filtered promotional email represented lost sales, and every abandoned cart email in spam meant a customer who didn't complete their purchase.

The Solution

DeliveredDaily implemented a comprehensive deliverability and email optimization strategy focused on maximizing revenue per subscriber while protecting sender reputation:

Infrastructure & Authentication Overhaul

• Migrated to dedicated IP infrastructure separating transactional from promotional sends
• Implemented strict DMARC enforcement to prevent spoofing and improve ISP trust
• Configured subdomain segmentation (cart recovery, promotional, transactional)
• Set up real-time blacklist monitoring and reputation tracking

Content & Compliance Optimization

• Rewrote email templates to avoid supplement industry spam triggers (health claims, miracle language)
• Restructured subject lines to maintain urgency without triggering filters
• Added required FDA disclaimers in compliant format that didn't hurt deliverability
• Optimized image-to-text ratios and removed excessive promotional language

Advanced Segmentation & Personalization

• Created purchase-based segments (protein customers, vitamin subscribers, specialty products)
• Implemented lifecycle automation (new customer, repeat buyer, VIP, lapsed)
• Deployed product-specific recommendations based on past purchases
• Established re-engagement campaigns for inactive segments

High-Priority Flow Optimization

• Rebuilt abandoned cart sequence with dedicated infrastructure achieving 96% delivery
• Created browse abandonment flows for high-margin specialty products
• Implemented post-purchase cross-sell sequences timed to reorder cycles
• Optimized subscription renewal reminder emails (recurring revenue driver)

Testing & Continuous Improvement

• Established A/B testing framework for subject lines, content, and send times
• Implemented inbox placement testing before major promotional campaigns
• Created pre-launch checklist for product release emails
• Set up weekly performance reviews and monthly deliverability audits

The Results

Within 4 months, the supplement brand's email channel transformed from a plateaued revenue source into a hyper-efficient growth engine:

The impact extended beyond just email metrics. With reliable deliverability and sophisticated segmentation, the brand could launch new products with confidence, knowing their promotional emails would reach customers who were most likely to buy based on purchase history and engagement patterns.

What the Head of Growth Had to Say

"Email went from a channel we were worried about to our most profitable growth lever. DeliveredDaily didn't just fix our deliverability—they helped us completely rethink our email strategy. We're now generating over $600K per month from email, and that number keeps climbing. The ROI on this partnership is absurd. Our CAC dropped, LTV increased, and email became the foundation of our growth strategy."

Long-Term Impact

The supplement brand now treats email as their primary revenue channel, generating over $7 million annually from their 180,000-subscriber list. They've since expanded to 240,000 subscribers while maintaining 95%+ inbox placement and continuing to scale revenue per subscriber.

With reliable deliverability infrastructure, they can confidently increase send frequency during promotional periods (product launches, seasonal sales) without fear of damaging sender reputation. Their abandoned cart sequences alone now generate $180K+ monthly in recovered revenue.

Perhaps most importantly, email deliverability is no longer a bottleneck to growth. When they launch new supplement formulations or expand into new product categories, they know their email infrastructure can support aggressive promotional campaigns while maintaining the inbox placement rates that drive conversions.
