Cancel Simple Email Service

I apologize for the confusion, but there isn't actually a way to "cancel" Amazon Simple Email Service (SES) in the way you might cancel a subscription service. SES is a pay-as-you-go service, which means you're only charged for what you use.

The charges you're seeing are for the usage you've already incurred. To stop future charges, you simply need to stop using the service. Here are some steps you can take:

1. Make sure you're not sending any more emails through SES.
2. Delete any configuration sets you may have created.
3. Remove any verified identities (email addresses or domains) you've set up.
4. If you've set up any receipt rules or rule sets, delete those as well.

If you want to completely prevent any potential future use, you can consider removing the SES permissions from your IAM users and roles.

Keep in mind that even after you stop using SES, you might see charges on your next bill for usage that occurred before you stopped. AWS typically bills in arrears, so there can be a delay between when you use a service and when you're billed for it.

If you're concerned about ongoing charges or have questions about your bill, it's best to contact AWS Support directly. They can provide specific guidance based on your account and usage.
