The Esellerate sent order history emails automatically, and I checked your orders, and they are all registered correctly to the same email address you used to register here so, if you are not receiving emails, the problem is surely on your side.
Perhaps your ISP has an anti-spam filter you are not aware of, which mistakenly blocks emails from Esellerate and you can't control it.
For these kind of questions, you should have used email support, not the forum, because we can't obviously share further private informations here.
