What happens when the receiver can't be reached by PEPPOL?

A controlled e-mail re-routing mechanism has been added to the platform. This means that when your receiver can’t be found in the PEPPOL directory, an email will be sent to the receiver, containing the UBL invoice, as well as a PDF attachment.

Caution; it is not a fallback channel. When delivery via PEPPOL fails after a succesful reachability check, the document is marked as failed and will not be sent via email.
