AWS SES Email Service

Scalable transactional email with high deliverability, IP pools, and configuration sets for analytics.

AWSIntermediate

Why

SES sends transactional email at $0.10/1k (cheapest) with high deliverability. 62k emails/mo free from EC2. Configuration sets track opens/bounces/complaints.

No SMTP server to manage.

When

Use for transactional email (password resets, receipts, notifications). Avoid for marketing (use Mailchimp) or if deliverability is critical (use SendGrid).

How

1. Verify domain — add DKIM/SPF records, or verify email for testing 2. Send — aws ses send-email, or SMTP interface with any client 3. Configuration set — tracks opens, bounces, complaints → SNS/CloudWatch 4. Templates — stored HTML, send with template data 5. IP pools — dedicated IPs for reputation isolation 6. Suppression list — auto-suppress bounces/complaints 7. Sandbox — 1 email/sec, 200/day, request production access 8. Metrics — CloudWatch, bounce/complaint rates must stay <5%

Example

# Send email via SDK import { SESClient, SendEmailCommand } from "@aws-sdk/client-ses"; const ses = new SESClient({}); await ses.send(new SendEmailCommand({ Source: "noreply@example.com", Destination: { ToAddresses: ["user@example.com"] }, Message: { Subject: { Data: "Your receipt" }, Body: { Html: { Data: "<h1>Thanks!</h1><p>Order #456</p>" } }, }, ConfigurationSetName: "transactional", })); # Verify domain (adds DKIM records to Route 53) aws ses verify-domain-identity --domain example.com

Common Problems

  • ⚠Sandbox limits — 200/day until production access granted, request via support
  • ⚠Bounces hurt reputation — keep <5%, use suppression list, validate emails
  • ⚠Gmail/Outlook filtering — set up DMARC, warm up IPs gradually

Best Practices

  • ✓Use configuration sets — track every send, route events to SNS for real-time alerts
  • ✓Implement suppression list — never send to bounced/complained addresses
  • ✓Set up DKIM + DMARC — improves deliverability, prevents spoofing
