My primary use of AWS is the Simple Email Service. I have been using it for a while as a simple email relay for small numbers of emails, no more than 10 a day. I am about to start using SES with an email marketing service though and want to be able to analyse the costs of each campaign sent. I sent one test campaign on the 9th of June, however, the costs of that campaign have not shown up in Cost Explorer. The campaign was sent using a sub AWS account of my Organization, but the costs aren't showing in the Cost Explorer of that account either. As the 9th was several days ago I would have thought it would show by now but I've not seen anything.
