What is AWS SES?
Amazon Simple Email Service (SES) allows you to send and receive emails using your email addresses and domains at a low cost and with high scalability. You can use SES to send marketing emails, transactional emails, and more. It eliminates the need to manage your email servers and provides powerful features to help you manage your email campaigns effectively.
Features of Amazon SNS
- Spam and Phishing Protection: Protect your reputation with built-in spam and phishing filters.
- Global Infrastructure: Send emails to recipients around the world.
- Encryption in Transit and at Rest: Encrypts your email data in transit and at rest.
- Monitoring and Logging: Monitor your SES usage and performance.
- Lambda Function Integration: Trigger a Lambda function when an email is received.
- Sender Identity Management: Manage the identities used to send email from your account.
Working of Amazon SES
Amazon Simple Email Service (Amazon SES) lets you reach customers confidently without an on-premises Simple Mail Transfer Protocol (SMTP) email server using the Amazon SES API or SMTP interface.
- Email Sending and Receiving: Sending Emails: SES allows you to send emails using a simple interface. You can send formatted HTML emails, plain text emails, or emails with attachments.
- Receiving Emails: SES can also be configured to receive emails, processing them according to the rules you define, like storing them in an Amazon S3 bucket, invoking a Lambda function, or bouncing unwanted mail. 3. SMTP Interface and API: SMTP (Simple Mail Transfer Protocol): SES supports sending emails through SMTP, a widely used protocol for sending emails. This allows easy integration with existing software that uses SMTP for email.API: SES also provides a set of APIs, allowing for programmatic control over sending, receiving, and managing emails.
Understanding Email Sending Limits and Costs
AWS SES uses a pay-as-you-go model, where you only pay for the emails you send and receive. There are no upfront costs or monthly fees. You are billed separately for sending and receiving emails, data usage, and additional features.
Free-tier accounts have a daily sending quota of 200 emails per day. If your account is in the sandbox, you can send one email per second. Paid accounts have higher quotas based on their service plan, and a single email size limit cannot exceed 10 MB in size, including attachments. Per-email cost: varies based on the region you send from and the recipient’s region. Prices start as low as $0.10 per 1,000 emails.

Integrating AWS SES with Other AWS Services
AWS SES seamlessly integrates with other AWS services, creating a powerful ecosystem for managing your email communication. Here are some key integrations:
1. Amazon S3:
- Store your email templates, attachments, and other email assets in S3 buckets for easy access and management.
- Configure SES to automatically send emails from S3 events, triggering email notifications upon file creation or upload.
Integration Steps:
- Store your email templates, images, or other content in an S3 bucket.
- When composing an email with SES, reference the content stored in the S3 bucket in your SES API calls.
- This separation makes it convenient to update email content without modifying your application code.
2. Amazon SNS:
- Send email notifications to SNS topics, triggering additional actions like mobile push notifications or Lambda function invocations.
- Use SNS to receive email replies and route them to specific applications or queues for processing.
Integration Steps:
- Create an SNS topic for bounces and another for complaints.
- Configure SES to publish bounce and complaint events to their respective SNS topics.
- Subscribe to these SNS topics with the necessary endpoints, such as an email address or an AWS Lambda function.
- Use the received notifications to update your email lists and handle opt-outs.
3. AWS Lambda:
- Trigger Lambda functions when emails are received, enabling automated processing and response workflows.
- Utilize Lambda to personalize email content based on recipient data or perform other custom logic.
Integration Steps:
- Create a Lambda function that contains the code you want to execute in response to SES events.
- Configure SES to invoke the Lambda function when specific events occur, such as when a new email is received or when there is a bounce.
- Write code within your Lambda function to handle SES events and perform the desired actions, such as updating a database or generating a dynamic email response.
Ensuring Email Security and Compliance with AWS SES
Amazon Simple Email Service (SES) is a robust platform that enables businesses to send transactional, promotional, and marketing emails at scale. When it comes to ensuring email security and compliance with AWS SES, several key points should be considered.
- AWS SES provides a secure and reliable infrastructure that employs industry-standard encryption protocols to safeguard sensitive information during transit. It supports Transport Layer Security (TLS) to encrypt emails in transit, protecting them from potential eavesdropping and tampering.
- SES allows for the integration of DomainKeys Identified Mail (DKIM) and Sender Policy Framework (SPF) to authenticate emails, reducing the risk of phishing attacks and ensuring that recipients can trust the origin of the emails they receive.
- AWS SES offers a dedicated IP address option, giving businesses greater control over their email reputation and making it easier to comply with deliverability best practices.
By leveraging these security and compliance features within AWS SES, businesses can establish a more trustworthy and reliable email communication channel with their customers while meeting regulatory requirements.
SES Best Practices
- Deliver content of genuine value that recipients actively seek and appreciate.
- Limit your email distribution to individuals who have willingly subscribed to receive communications.
- Regularly remove recipients who haven’t engaged with the business recently by facilitating an uncomplicated unsubscribe process.
- Maintain low bounce and complaint rates by promptly eliminating bounced or complained addresses.
- Utilize the Amazon Simple Notification Service (SNS) to oversee these instances, treating them akin to opt-outs.
- Keep a vigilant eye on your email-sending activity, ensuring it aligns with best practices and compliance standards.

Hi Deepthi,
The post is really good and informative. In the comparison between Amazon SES and SQS you can also add SNS as Amazon SNS also supports Email notifications. This is just a suggestion.
The second section heading is mentioned as ‘Features of Amazon SNS(Simple Notification Service)’.Do you mean SNS or SES (Simple Email Service) as they both are different?
Thanks,
Rajesh
