Your orders are all correctly registered to your email address so, the emails has surely been all sent by Esellerate automatically.
Check your spam folder, and be sure your ISP doesn't have some kind of automatic spam filtering enabled, so the emails might have been filtered directly on your ISP email server. Usually, ISP give the ability to disable these filters.
If still doesn't work, let me know, and I'll try sending the orders in a different way.
