How AI Emails Drove Higher Engagement and Sales
In the competitive world of direct-to-consumer (DTC) fitness apparel, a well-known brand was struggling to turn its loyal customer base into consistent revenue. Despite a 20% month-over-month growth in website traffic, their email campaigns were underperforming, with lackluster open rates and stagnant sales. But within 5 months of partnering with Lettora.ai, the brand doubled email-driven revenue, transforming its strategy from generic blasts to hyper-targeted, AI-optimized campaigns. Here’s their journey from stagnation to success.
The Challenge: Missed Opportunities in a Crowded Market The brand faced three critical hurdles:
Low Engagement: Emails had a 12% open rate, far below the 23% industry average for apparel.
Ineffective Personalization: Subscribers received the same promotions, regardless of purchase history or preferences.
Time-Intensive Workflows: The team spent hours A/B testing subject lines and segmenting lists manually, with minimal ROI.
“We were drowning in data but couldn’t translate it into action,” admits the Head of Marketing.
The Solution: Lettora.ai’s AI-Driven Email Suite The brand implemented Lettora.ai’s Smart Campaign Builder and Predictive Analytics tools, focusing on three AI-powered features:
Behavior-Based Segmentation: AI analyzed purchase history, browsing behavior, and workout preferences (e.g., yoga vs. CrossFit enthusiasts).
Dynamic Content Blocks: Product recommendations auto-updated based on real-time inventory and user intent.
Send-Time Genius: Emails delivered at optimal times (e.g., 6:00 AM for early-morning gym-goers, 8:00 PM for post-workout shoppers).
The Implementation: A 3-Stage Process
Data Integration & Insights
Connected the brand’s Shopify store, email platform, and social media feeds to Lettora.ai.
AI identified high-value segments like “Luxury Legging Loyalists” and “First-Time Buyers.”
Hyper-Personalized Campaigns
Abandoned Cart Series: AI added urgency with messages like, “Your Gym Bag is Incomplete—Claim 15% Off Before These Shorts Sell Out!”
Post-Purchase Nurture: Recommended complementary items (e.g., “Pair Your Running Shoes with Sweat-Wicking Socks”).
Flash Sale Automation: Targeted inactive subscribers with AI-generated discounts like “We Miss You! Enjoy 20% Off Renewal Essentials.”
Real-Time Optimization
Lettora.ai tested 100+ subject line variations, finding winners like “Your Next Workout Look is 30% Off 👟” (outperforming generic “Sale Inside!” by 300%).
The Results: 2X Revenue in 5 Months 📈 100% Revenue Growth: Email-driven sales jumped from $200K to $400K monthly.
🔥 28% Open Rate: Surpassing the apparel industry average by 5 points.
🛒 18% Click-to-Purchase Rate: Driven by personalized product carousels.
⏱️ 60% Time Saved: The team reclaimed 25+ hours/week to focus on creative campaigns.
“Lettora.ai didn’t just automate our emails—it made them smarter. We’re now scaling personalization without scaling headaches,” says the Head of Marketing.
