Rough idea for a bash script to export suppressed email addresses using AWS CLI + jq

exportSesSuppressions.sh

#! /bin/bash

token=""
tmpjsonfile="..path to a tmp file for storing json responses from aws.."
csvfile="..path to your export csv file here.."
command="aws sesv2 list-suppressed-destinations --page-size 1000"

echo "email,reason,date" > $csvfile

while true; do
    echo "Fetching page from AWS..."
    
    if [[ -z "$token" ]] ; then
    	$command > $tmpjsonfile
    else
    	$command --next-token "$token" > $tmpjsonfile
    fi

    jq '.SuppressedDestinationSummaries[] | [.EmailAddress, .Reason, .LastUpdateTime] | @csv' $tmpjsonfile >> $csvfile

    token=$( jq -r '.NextToken' $tmpjsonfile )

    [[ -n "$token" && "$token" != "null" ]] || break
done

echo "All done!"

V rough - please feel free to refine :)
