Serverless Email Marketing App using AWS and Terraform

This is a simple, serverless email marketing system built using AWS and Terraform. It automatically sends bulk HTML emails (like a newsletter) using SES, triggered by EventBridge on a schedule. Email templates and contact lists are stored in Amazon S3, and email sending is handled by a Lambda function.

Real Use Case

I built this for my food blog to send out a weekly newsletter to my subscribers with recipe ideas and seasonal cooking tips. Instead of using a paid email tool, I built a cost-effective and automated solution using AWS.
