Hi fellow devs,
I've created a short article on how to create nice looking CloudWatch alarms with Lambda, SES and CDK.
You can find the article here: https://towardsaws.com/how-to-customise-cloudwatch-alarm-notifications-with-lambda-ses-html-and-cdk-f0094b07fed6
And the source code here: https://towardsaws.com/how-to-customise-cloudwatch-alarm-notifications-with-lambda-ses-html-and-cdk-f0094b07fed6
I came over the task in several roles already and hope it can help.
