To remove an email address from a suppression list using the Amazon SES command line interface (CLI), you can use the remove-email-identity-from-suppression-list command. The basic syntax is as follows:
aws sesv2 delete-suppressed-destination --email-address firstname.lastname@example.org
This command will remove the specified email address from the suppression list for your AWS account.
Please make sure you have the right AWS CLI and SES permissions to execute this command.
