SES + SNS delivery status in batch

Hi,

We're using SNS to send HTTP requests to our endpoint. That's how we record delivered, sent, bounced, etc.

If we send 500,000 emails this means we will receive 500,000 requests. I wonder whether is it possible to bulk this? It would be great if there is something like this:

{"items": [{"messageId": 123"}, {"messageId": 456}]}

I haven't been able to find such solution.

Thanks, Nedim
