S3 Bucket → SNS → Email

For every object removal from the S3 Bucket, the SNS Topic Subscription will send an email notification. Once the stack is deployed it will send an email confirmation to subscribe to the SNS topic. After subscribing to the SNS topic, you will receive an email notification for every object removal from the S3 Bucket. When naming the bucket, it must be unique globally. If you get the "Bucket name already exists" error, you must use a different bucket name to create the bucket.

NOTE: Update the EmailSubscription endpoint on the s3-sns-stack.ts file.
