Record Email with AWS Lambda (they don't seem to include the body, in the end I got it by saving to an S3 bucket)

	'use strict';
	// When selecting the fn, you have two ways to call it:

	// "RequestResponse" - Logs the return value (maybe does more, but it cares about the return value, at the very least)
