Anmazon SES

Amazon Simple Email Service (SES) is a cloud-based email service designed to send and receive email, either for transactional communications, marketing campaigns, or to receive messages via email routing. Here are the key aspects to be aware of when working with SES:

1. Sending and Receiving Emails​

  • Sending Emails: SES allows you to send transactional, bulk, and marketing emails programmatically via SMTP, AWS SDKs, or AWS CLI. It's highly customizable to meet various use cases, from sending order confirmations to large-scale email campaigns.
  • Receiving Emails: SES also provides inbound email processing, allowing you to receive emails and perform actions on them, such as filtering, storing, or triggering AWS Lambda functions.

2. Verified Identities​

  • Before sending emails, you need to verify the email addresses or domains that you intend to send emails from. This verification helps prevent spam and spoofing.
  • Domain Verification: You can verify an entire domain, allowing you to send emails from any address in that domain.
  • Email Verification: Individual email addresses can be verified for sending, which is useful for testing purposes.

3. Sandbox and Production Modes​

  • When you first start using SES, your account will be in the sandbox environment. In this mode, you can only send emails to verified email addresses and are subject to sending limits.
  • To use SES in production mode, you need to submit a request to remove sandbox restrictions, which will allow you to send emails to any recipient and raise your sending limits.

4. Sending Quotas and Limits​

  • SES has sending quotas, which include:
    • Sending Limit (Emails Per Day): The number of emails you can send per 24-hour period.
    • Sending Rate (Emails Per Second): The maximum number of emails you can send per second.
  • These limits are adjustable, and you can request increases as needed.

5. Deliverability and Reputation Management​

  • Email Deliverability: SES includes features to improve deliverability, such as monitoring bounce rates and feedback loops from ISPs.
  • Reputation Dashboard: SES provides a dashboard that helps you track your sender reputation, giving you insights into bounce rates, complaint rates, and best practices to improve deliverability.
  • Dedicated IP Addresses: You can use dedicated IP addresses for sending, giving you more control over your sending reputation.

6. Configuration Sets and Email Event Monitoring​

  • Configuration Sets: These are groups of rules that you apply to your outgoing emails, allowing you to control what happens when emails are sent. This can include metrics collection, bounce/complaint feedback handling, or event tracking.
  • Event Destinations: You can track the delivery of your emails using event destinations like Amazon CloudWatch, Amazon Kinesis Data Firehose, or Amazon SNS to receive real-time notifications of sending events such as bounces, deliveries, and complaints.

7. Authentication and Security​

  • DKIM and SPF: SES supports DomainKeys Identified Mail (DKIM) and Sender Policy Framework (SPF) for email authentication to enhance email deliverability and reduce the likelihood of your emails being marked as spam.
  • IAM Permissions: You can use AWS Identity and Access Management (IAM) to control access to SES, specifying which users can send emails, view settings, or configure domains.

8. Email Content and Templates​

  • Personalized Content: SES supports both raw and templated email messages, enabling personalized content with variable substitution.
  • Templated Emails: You can create and store email templates in SES and use them to send dynamic, personalized emails.

9. Transactional vs. Bulk Email​

  • SES supports both transactional emails (e.g., order confirmations, password resets) and bulk emails (e.g., newsletters, promotional content).
  • It's crucial to manage your list hygiene (handling bounces, unsubscribes, and complaints) to maintain a good sender reputation, especially when sending bulk emails.

10. Cost-Effective Pricing​

  • SES is designed to be cost-effective, with pay-as-you-go pricing based on the number of emails sent and received, data volume, and additional features like dedicated IPs.
  • Free Tier: If you're using SES from an application hosted in Amazon EC2, you get a certain amount of outbound email messages free each month.

11. Integration with Other AWS Services​

  • SES integrates seamlessly with other AWS services, such as:
    • Amazon SNS: For real-time notifications of email delivery events.
    • AWS Lambda: For processing inbound emails or handling email delivery events programmatically.
    • Amazon S3: For storing inbound email content or attachments.

12. Best Practices​

  • List Hygiene: Regularly clean up your mailing lists to avoid sending to non-existent or invalid addresses.
  • Complaint and Bounce Handling: Monitor and act on feedback from ISPs to improve sender reputation.
  • Sending Practices: Follow best practices for email sending (e.g., respecting unsubscribe requests, adhering to CAN-SPAM regulations).
