Example
You tried to send to recipient(s) that have been marked as inactive. Found inactive addresses: joe@example.com. Inactive recipients are ones that have generated a hard bounce, a spam complaint, or a manual suppression.
Explanation
The distribution notification email failed to be delivered to the specified addresses. If the distribution channel has an associated destination, the uploading of assets to the destination was not affected. Only the notification failed.
I insist on sending to that address
An email address that has generated a hard bounce can be reactivated on request. Before submitting such a request, confirm with the recipient that the address is correct.
Repeat deliveries to a nonexistent address leads to spam complaints and ISP blacklisting.
An email address that has submitted a spam complaint cannot be reactivated.
