You can also configure ListBuckets for each folder, like so

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "AllowSESPuts-1521238702575",
            "Effect": "Allow",
            "Principal": {
                "Service": "ses.amazonaws.com"
            },
            "Action": "s3:PutObject",
            "Resource": "arn:aws:s3:::buckets.email/*",
            "Condition": {
                "StringEquals": {
                    "aws:Referer": "[red]"
                }
            }
        },
        {
            "Sid": "Stmt1586754972129",
            "Effect": "Allow",
            "Principal": {
                "AWS": "arn:aws:iam::596322993031:user/[red]"
            },
            "Action": "s3:ListBucket",
            "Resource": "arn:aws:s3:::buckets.email",
            "Condition": {
                "StringEquals": {
                    "s3:delimiter": "/",
                    "s3:prefix": [
                        "",
                        "domain.co",
                        "domain.co/user"
                    ]
                }
            }
        },
        {
            "Sid": "Stmt1586754972129",
            "Effect": "Allow",
            "Principal": {
                "AWS": "arn:aws:iam::596322993031:user/[red]"
            },
            "Action": "s3:ListBucket",
            "Resource": "arn:aws:s3:::buckets.email",
            "Condition": {
                "StringLike": {
                    "s3:prefix": "domain.co/user/*"
                }
            }
        },
        {
            "Effect": "Allow",
            "Principal": {
                "AWS": "arn:aws:iam::596322993031:user/[red]"
            },
            "Action": [
                "s3:GetObject",
                "s3:PutObject",
                "s3:DeleteObject"
            ],
            "Resource": "arn:aws:s3:::buckets.email/domain.co/user/*"
        }
    ]
}

These rules are used together with SES to receive an email, but allows an external user to view the files that were put in the bucket by SES. I followed the instructions from here: https://aws.amazon.com/blogs/security/writing-iam-policies-grant-access-to-user-specific-folders-in-an-amazon-s3-bucket/

Also, you must specify prefix as domain.co/user/ WITH slash at the end when using the SDK, otherwise you'll get access denied. hope it helps anyone
