Amazon SES

Amazon Simple Email Service (SES) is a scalable email platform that handles both outgoing and incoming email. You can send transactional messages like password resets, marketing campaigns, and bulk notifications through a simple API or SMTP interface. It integrates with other AWS services such as Lambda and SNS for event-driven workflows.

SES supports dedicated IP addresses, custom DKIM signing, and SPF validation to improve deliverability. It offers detailed sending statistics, bounce and complaint tracking, and a suppression list for managing bounces. The service works with any application that can send SMTP or REST API calls, and it can receive emails via S3, SNS, or Lambda.

This tool is ideal for developers and businesses already on AWS who need reliable email infrastructure without managing servers. Pricing is pay-as-you-go based on volume, with a free tier of 62,000 messages per month when sent from EC2. It is a proprietary service from Amazon Web Services.
