In this lesson we cover Amazon Simple Email Service (SES) — a scalable, cloud-based email platform for sending and receiving transactional and bulk email. SES leverages AWS infrastructure to improve deliverability, reduce bounces, and handle high-volume email traffic for applications and businesses of any size.
The slide titled "What Is SES?" shows Amazon Simple Email Service (SES) sending an email (icon and arrow) and a right-hand panel listing benefits: AWS infrastructure, reduced email bounces/delivery failures, and support for high-volume traffic.
SES is regional and accounts often begin in a sandbox environment with sending restrictions. To send to unverified recipients or increase quotas, request production access through the AWS Support console.

Core components of an SES deployment

​
Quick CLI examples

Verify a domain identity:
Generate DKIM tokens for DNS:
Note: After running these commands, add the returned TXT records to your domain’s DNS to complete validation.

​
Authentication and deliverability features

  • DKIM (DomainKeys Identified Mail): Cryptographic signing that verifies a message was authorized by the sending domain.
  • SPF (Sender Policy Framework): DNS records that list mail servers allowed to send for your domain.
  • DMARC (Domain-based Message Authentication, Reporting, and Conformance): Policy and reporting built on SPF and DKIM to reduce domain abuse.
SES provides a reputation dashboard that surfaces deliverability issues (bounce and complaint rates, spam trap warnings, etc.), helping you monitor and improve email health.

​
Key features

  • Email templates — Create and reuse templates to personalize messages (for example, customer name or order details) and send them via the SES API or SMTP.
  • Receiving emails — Accept inbound emails for verified domains and apply receipt rules to store or process inbound messages.
  • Mailbox simulator — Simulate bounces, complaints, and other scenarios to validate how your application reacts without impacting production reputation.
  • Suppression lists — Manage addresses that should not be contacted due to prior bounces/complaints; can be account-level or configuration-set-level.

​
SES integrations

SES natively integrates with several AWS services to enable processing, storage, notifications, and custom logic:

​
Common use cases

  • Automated transactional messages — Order confirmations, shipping notifications, password resets, and other time-sensitive messages that require reliable delivery.
  • Bulk email communications — Newsletters, promotional campaigns, and announcements where deliverability and sender reputation must be managed at scale.
Presentation slide titled "SES – Use Cases." It shows two colored cards: an orange card labeled "Automate Transactional Messages" with a cash-register icon, and a pink card labeled "Send Bulk Email Communications" with an envelope icon.
Monitor deliverability metrics (bounce and complaint rates). High rates can lead to account throttling or suspension. Use the mailbox simulator, suppression lists, and configuration sets to test and protect your sender reputation.
