We have reconfirmed that we are not on any blocklists, so there shouldn't be any email providers blocking all mail originating from us simply because of that origin.
Can you find the affected sales in your E-junkie Seller Admin > View/Download Transaction Log? If not, that indicates we haven't processed those sales because the payment processor (PayPal/etc.) never sent us notification of payment, so you should verify whether the payment was actually completed in your payment account. Our system has no way of knowing whether an order was ever actually placed until we receive that payment notification.
If the affected checkout went through a payment processor you've recently added, and if you have not successfully fulfilled any sales from that new processor with E-junkie before, double-check every step of our procedure required to integrate their service with ours:

If you do find an affected sale in your E-junkie Transaction Log, that indicates we received payment notification and processed that sale, so the next step is to figure out why the buyer did not receive their thank-you email with the link to their thank-you/download page:
- Ask the buyer to look in their spam folder, and mark the message as Not Spam to help train their email provider's spam filter. To reduce the chances of something in the email triggering spam filters, you may want to consider paring down your Thank-you Email messages to the bare minimum (just a thanks with a link to the thank-you/download page) and save any promotional/marketing text and other links for your thank-you page rather than the email.
- Check the product's settings, and if Enable Templated Email is checked, make sure you have typed a template into the Email Message field that includes either [%download_link%] or [%thankyou_link%], or uncheck Enable Templated Email to have our system send buyers our standard message and link.
- If you'd deliberately checked Enable Templated Email and left the Email Message field blank in order to disable product-specific thank-you email, then make sure you have a message typed into your Seller Admin > Account Preferences > Common Thank-you Email, and make sure you included [%thankyou_link%] somewhere in your message template there.
