Email Platform Migration: $35K Monthly Savings Case Study

Impact Statement

A strategic email platform migration achieving 85% cost reduction ($35K/month) while improving deliverability by 50%.

Overview

Strategic migration from expensive legacy email platform to cost-effective modern solution with automated template generation and improved deliverability. Executed complex 6-month migration while maintaining zero downtime for ongoing campaigns.

Key Outcomes

• $35k monthly cost reduction (85% savings)
• 50% improvement in email deliverability rates
• 90% reduction in template creation time
• Zero downtime during migration

Technical Stack

• Backend: Node.js with programmatic template generation
• Templates: Handlebars for dynamic content rendering
• Email Service: AWS SES for cost-effective delivery
• Automation: n8n for workflow orchestration
• Database: PostgreSQL for campaign and subscriber management

Challenge Context

High-volume email platform costing $42k/month with limited customization options and declining deliverability rates. Manual template creation process requiring developer resources for simple changes. Need for seamless migration without interrupting ongoing campaigns.

Systematic Approach

1. Analysis & Planning

• Comprehensive analysis of email volume and feature requirements
• Evaluation of modern email service providers and cost structures
• Migration strategy development with parallel tracking
• Compliance and deliverability requirements assessment

2. System Development

• Development of programmatic template generation system
• Automated testing framework for email rendering across clients
• Integration with existing CRM and analytics systems
• Delivery infrastructure setup with AWS SES

3. Migration Execution

• Phased migration with parallel tracking and validation
• Template conversion with automated testing
• Deliverability monitoring and optimization
• Team training on new workflow and tools

4. Optimization & Handoff

• Performance monitoring and cost validation
• Non-technical team member training
