How do I Create a CloudWatch Email Alert With Custom Content?

Question

I am trying to edit an AWS CloudWatch alert that sends an email to my team such that custom content is sent in the email. Currently, all email alerts contain only auto-generated content. The email content contains the reason for the alert, a link to the alarm in the AWS console, and sections for Alarm Details, Threshold, and Monitored Metric. However, I want to add custom content listing likely causes of the alert and procedures to execute when receiving the alert. Does anybody know how custom content can be added to a CloudWatch alert email?

I have read existing AWS CloudWatch Alarm documentation such as How to Create/Edit a CloudWatch Alarm, and How to create a CPU Usage Alarm that Sends an Email. I have also tried various Google searches and searches for existing questions here on SO but to no avail. Any help/advice would be greatly appreciated.

Answer 1

You can setup a Lambda trigger to the alarm and send an email using AWS SES SMTP credentials, creating a formatted email content with alarm trigger event data.
