Can you provide any additional details, such as which domain you are attempting to send the emails from? I'm having trouble finding results for your account in our email logs. Keep in mind that if the recipient server is discarding your email as spam, there is little we can do about it -- you will need to work to improve your email headers/content so that it is no longer detected as spam. If the email is being blocked by our server, I could provide a bit more insight as to why, but I need to find the emails in question first which I'm having trouble doing.
