The Power of HTML Email Templates with Amazon SES

Voiced by Amazon Polly


In today’s fast-paced software development landscape, continuous integration and delivery (CI/CD) pipelines are indispensable for automating the build, test, and deployment processes. AWS CodeBuild is an Amazon Web Services (AWS) managed service that facilitates efficient code building, testing, and packaging. On the other hand, Amazon Simple Email Service (SES) provides a reliable platform for sending transactional and marketing emails.

AWS CodeBuild and Amazon SES

AWS CodeBuild simplifies the process of building and testing code across various programming languages and environments. It seamlessly integrates with other AWS services and allows for customization through build spec files. Meanwhile, Amazon SES offers a scalable and cost-effective solution for sending emails, ensuring high deliverability rates and compliance with email regulations.

Prerequisites for Email Notifications

Several prerequisites must be addressed before implementing custom email notifications in AWS CodeBuild using Amazon SES. Firstly, the AWS IAM role assigned to AWS CodeBuild must have the necessary permissions to interact with Amazon SES, including permissions to send emails (ses:SendEmail) and send raw emails (ses:SendRawEmail). Additionally, the sender and recipient email addresses must be verified if SES is in sandbox mode. However, in production mode, only the sender’s email address must be verified.

To ensure proper configuration, developers should create an AWS IAM policy granting the required permissions and verify email addresses as per Amazon SES requirements.

Integration with BuildSpec File

The provided BuildSpec file showcases how to integrate Amazon SES CLI commands to send custom email notifications at different stages of the AWS CodeBuild process. In this enhanced version, we’ll incorporate HTML email templates stored in an Amazon S3 bucket.

In the pre_build phase, we download the HTML email template from the Amazon S3 bucket and make the necessary substitutions for the dynamic content. Then, during the build phase, the customized HTML email template sends the notification via Amazon SES if a build failure occurs.

Explanation of Amazon SES Command: The aws ses send-email command allows developers to programmatically send emails through Amazon SES. Here’s a detailed explanation of its components:

  • –from: Specifies the sender’s email address.
  • –destination: Specifies the recipient’s email address.
  • –message: Specifies the email subject and body. This includes specifying the subject with Subject={Data=’SubjectText’,Charset=utf8} and the body with Body={Text={Data=’BodyText’,Charset=utf8}}.

HTML Email Template


By leveraging HTML email templates in Amazon SES for custom email notifications in AWS CodeBuild, developers can enhance the visual appeal and informational content of their notifications. This improves communication and clarity within CI/CD pipelines, enabling stakeholders to stay informed about build successes, failures, and other critical events. With proper configuration and integration, teams can ensure timely responses to build events, fostering collaboration and efficiency in software development workflows.
