Overview
This case study examines how a mid-sized e-commerce brand leveraged strategic email marketing to increase revenue, engagement, and customer lifetime value over a 90-day period.
Company: BrightBlend Co. (Fictional)
Industry: E-commerce (Health & Wellness)
Primary Goal: Increase repeat purchases and email-attributed revenue
The Challenge
BrightBlend Co. had a growing email list of over 120,000 subscribers, but performance had plateaued.
Key challenges included:
Low open rates (18%)
Inconsistent click-through rates (1.9%)
Heavy reliance on promotional emails
Minimal audience segmentation
Underperforming abandoned cart emails
The brand needed a scalable strategy to re-engage subscribers and increase revenue without increasing ad spend.
The Strategy
A data-driven, customer-centric email marketing strategy was implemented, focused on personalization, automation, and lifecycle marketing.
1. List Segmentation
Subscribers were segmented based on:
Purchase history
Engagement level

Customer lifecycle stage (new, active, at-risk, loyal)
2. Email Automation
New automated flows were launched, including:
Welcome Series (3 emails)
Abandoned Cart Series (2 emails)
Post-Purchase Education & Upsell Series
Re-Engagement Campaign
3. Content Optimization
Emails were redesigned to:
Use shorter, benefit-driven subject lines
Focus on value-first messaging
Include social proof (reviews, testimonials)
Feature clear, single CTAs
4. Personalization
Dynamic content blocks were used to personalize:
Product recommendations
Subject lines
Send times based on engagement data
Execution
The new strategy was rolled out over 90 days using an email service provider with advanced automation and analytics.
A/B testing was conducted on:
Subject lines
CTA placement
Email length
Visual vs. text-heavy layouts
Results
After 90 days, BrightBlend Co. saw measurable improvements across key metrics:

Click-Through Rate: Increased from 1.9% to 4.6% (+142%)
