I am not receiving Sale Notification emails from E-junkie
First, from your E-junkie Dashboard go to View Order History > Transaction Log and see if you can find the affected sale. If it does not appear there, we have not yet received confirmation of payment from the payment processor, so our system has no way of knowing the order was actually placed.
Double-check every step of our integration procedure for the payment service where you received the affected buyer's payment, to make sure you haven't overlooked anything or made any mistakes; our integration page for each payment service also includes a Troubleshooting section near the bottom with links to additional information (e.g., for PayPal).
If you can find the affected order in your E-junkie Transaction Log, that confirms we did process that order. All notifcations from our system would be sent to the Login Email for your E-junkie account, so next you can look in your Spam/Junk Mail folder for that email address to see if your email provider has mistaken the missing Sale Notification email for spam; if you find the message there, be sure to mark it as Not Spam, and it may be a good idea to add and to your spam filter's whitelist (if you have one) as well as your address book or contact list, to help ensure delivery of notifications from our system in the future.
If you still can't find any Sale Notification emails from us, you can contact us to see if those emails might be disabled for your E-junkie account.
