Who it's for

Developers and businesses on AWS who need a scalable, low-cost way to send and receive transactional, marketing, or bulk email without running their own mail servers.

What you get

A pay-as-you-go email platform with a REST API, SMTP interface, stored/inline email templates, inbound email receiving, an account-level suppression list, standard and managed dedicated IPs, Virtual Deliverability Manager insights, and sending activity metrics via CloudWatch, Data Firehose, or SNS notifications.

How it works

You verify a sending domain or address in the AWS Console, then send email through the SES API, an AWS SDK, or SMTP credentials; SES handles delivery infrastructure and IP reputation, and publishes sends, bounces, and complaints as events you can route to SNS, CloudWatch, or Firehose.
