Enhancing AWS CodeBuild with Custom Email Notifications using Amazon SES


In modern software development workflows, continuous integration and delivery (CI/CD) pipelines are crucial in automating the build, test, and deployment processes. AWS CodeBuild is a managed service that enables developers to build, test, and package their code efficiently. On the other hand, Amazon Simple Email Service (SES) is a powerful tool for reliably sending transactional and marketing emails.

AWS CodeBuild and Amazon SES

AWS CodeBuild simplifies the process of building and testing code in various programming languages and environments.

It integrates seamlessly with other AWS services and allows for customization through build spec files. On the other hand, Amazon SES provides 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. This includes permissions to send emails (ses:SendEmail) and send raw emails (ses:SendRawEmail). Additionally, if Amazon SES is in sandbox mode, the sender and recipient email addresses must be verified. However, only the sender’s email address must be verified in production mode.

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

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. For instance, upon encountering a build failure, an email notification is triggered using the aws ses send-email command. This command includes essential details such as the sender, recipient, subject, and body of the email.

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}}.


By leveraging Amazon SES for custom email notifications in AWS CodeBuild, developers can enhance visibility and communication within their CI/CD pipelines. Whether it’s notifying stakeholders about build successes, failures, or other critical events, Amazon SES provides a reliable and scalable solution. With proper configuration and integration, teams can ensure timely responses to build events, fostering collaboration and efficiency in software development workflows.
