Email PO PDF to suppliers

Hi,

We email PO PDF to suppliers.

In case there is any problem with the email and the PO PDF is not delivered to the supplier.

Is there a error report which we need to monitor for failed emails.

How are other companies dealing with this situation ?

We do not use PO acknowledgement functionality.

We generally email POs to suppliers with 'PO Output for Communication'

One supplier told that he never received a PO.

How can we track the failed PO deliveries ?

Regards,

Emma
