# Automated Image Pipeline & CloudFront Savings Bundle: 30% Cost Reduction for SaaS Email Platform

> Built an automated image optimization pipeline and enrolled in CloudFront Savings Bundle to cut delivery costs by 30% while improving global email load times.

## Challenge: Rising CloudFront Costs and Unoptimized Image Delivery for Email Campaigns

TargetBay is a customer engagement SaaS company serving over 4,500 e-commerce brands via its BayEngage platform. Each marketing campaign features dynamic, high-resolution images that must load quickly in email clients across the globe. As the platform scaled, three critical issues emerged:

- **Rising CloudFront Costs:** Campaign volume and image resolution continued to increase, driving CloudFront egress costs upward with no structural mechanism to control spending.
- **Performance Bottlenecks:** Unoptimized images — often oversized or served in legacy formats — caused longer email load times, degrading the end-user experience and impacting campaign engagement metrics.
- **Manual Workflows:** Marketing teams were manually resizing and compressing images before upload, creating inconsistency across campaigns and consuming time that should have been spent on creative and strategic work.

## Solution: Automated Image Pipeline and CloudFront Savings Bundle Enrollment

FactualMinds designed and implemented a two-pronged approach: an automated image processing pipeline to eliminate manual workflows and a cost optimization strategy to reduce CloudFront egress spending.

**Automated Image Processing Pipeline:**

- Images are automatically resized if they exceed 1,200px width, ensuring consistent dimensions without manual intervention
- Adaptive compression is applied based on image type, balancing visual quality with file size
- WebP conversion is performed for JPEG and PNG assets when the conversion yields a smaller file, delivering modern formats to supported clients
- All processed images are stored in Amazon S3, ensuring every asset is lightweight, consistently formatted, and ready for global delivery

**CloudFront Savings Bundle:**

- Enrolled TargetBay in a 1-year CloudFront Savings Bundle at the 500 TB/month tier
- Secured approximately 30% discount on standard egress rates
- Established a predictable, lower data transfer billing model aligned with TargetBay's usage patterns

## AWS Services Used for CloudFront Cost Optimization

- **Amazon CloudFront** — Low-latency global delivery with edge caching for optimized images
- **Amazon S3** — Durable, highly available storage for processed image assets
- **AWS Savings Plans (CloudFront Savings Bundle)** — Committed-use discount model for egress cost reduction
- **Amazon CloudWatch** — Monitoring for egress volume, cache hit ratios, and performance metrics

## Results: 30% CloudFront Cost Reduction with Automated Image Optimization

The combined approach delivered immediate cost savings and operational improvements:

- **Approximately 30% reduction in CloudFront costs** through the Savings Bundle and reduced egress volume from smaller image payloads
- **Fully automated image optimization** eliminating manual resize and compression workflows for marketing teams
- **Faster email load times globally** as optimized images and edge caching reduced time-to-render across regions
- **Predictable billing model** replacing variable egress costs with committed-use pricing aligned to actual usage
