The domain list-manage.com is for a MailChimp server, and the URLs returning this error are for a MailChimp integration method that they stopped supporting a few years ago, though apparently many integrations already set up with these old URLs continued to work for some time, up until now. All this error notification means is that MailChimp is no longer accepting buyer info via this old integration method; our system is otherwise processing affected orders normally (issuing links, sending emails, logging the order details, etc.)

If you are no longer using MailChimp with E-junkie, you can simply delete the obsolete notification URL from your E-junkie settings, depending on the Subject of the notification emails:

• Subject: Server not notified for [Transaction ID here]
  In Seller Admin go to Manage Seller Account > Edit Preferences > Webhooks & Integration and delete the Common Notification URL there.

• Subject: Server not notified for item_name "[Product Name Here]"
  In Seller Admin go to Manage Products > Edit Products and select that product name, click View/Edit Product, then scroll down to the Webhook Integration section and delete the Product Notification URL there.

If you do wish to continue using MailChimp integration, we recently rolled out a new integration using their latest supported method, which this help page explains how to set up:

You just need to delete any obsolete MailChimp URL(s) from your E-junkie Webhook notification settings:
