I need to find more details of using SES Verified identity wise

To track the usage of each verified identity stats, you do not have a straight solution. But you can implement this small architecture or modify as you like to have a dashboard for your metrics.

1. Your application or backend system is responsible for sending emails through Amazon SES. It keeps track of the number of emails sent for each verified identity. So, whenever a mail is being sent, try to create and upload a json file with all necessary data to a s3 bucket. Example, From address, Time, To address, and similar important data you require to view.

2. Then, a Amazon Glue Crawler crawls on this bucket and stores this data into a database catalog.

3. Use athena to query these database as a source of your quicksight and then create a dashboard to visualize.
