How to build a serverless mass email solution with Amazon SES

This article demonstrates how to build a cost-effective serverless mass email solution using Amazon SES, Step Functions, API Gateway, and DynamoDB to send millions of emails at scale.

• Serverless architecture reduces costs from millions annually to approximately $300 per 2 million email campaign
• Frontend provides user-friendly GUI for campaign creation, template management, and monitoring via Amazon Cognito authentication
• Backend orchestrates email delivery through Step Functions workflow, batch processing with SQS, and DynamoDB audit trails
• Automatically scales from thousands to millions of emails without manual infrastructure provisioning or idle server costs
• Provides security via IAM roles, comprehensive logging for compliance, and data encryption in transit and at rest

This serverless approach eliminates traditional email infrastructure complexity while delivering scalability, reliability, and cost-effectiveness for large-scale email campaigns.
