AWS SES Quota Checker

I need a compact script that polls Amazon SES and returns the current “SendingQuota” and “MaxSendRate” for several accounts. So the script must:

• Accept a list of Access Key / Secret Key pairs, validate that each key really belongs to the target account, then authenticate on that account only.
• Loop through any number of credentials automatically—multi-account support is essential.
• Retrieve and output the quota values in a clear, human-readable format (stdout is fine). A simple timestamped CSV log written alongside the run would be helpful, but no other alerting is required.

Implementation notes
– Python 3 with boto3 (or an equally lightweight alternative) is preferred.
– Keep external dependencies to a minimum; standard ​pip install …​ is acceptable.
– Provide a brief README covering IAM permissions, required libraries, and an example command such as:
python check_ses_quota.py keys.csv

Acceptance criteria
If I can run the above command and immediately see an accurate quota report for every key in my list—without editing the code—then the job is complete.
