Undelivered Emails Saved Search

The Undelivered Emails saved search helps users analyze email deliverability problems. Go to Lists > Mailing > Undelivered Emails. The search results provide information logged for undelivered email messages. Fields in each log record include:

Sent Date
Log Date: Date and time when the message to a recipient bounced. The Undelivered Emails search results show one line per recipient. The log is created when the bounce occurs, so could be created almost immediately after sending, or at some time after the email was sent.
From
Recipients: A comma-separated list of the original recipients to whom a specific email message was not delivered.
Subject
Compliance Verified Denotes undelivered email messages because they failed to meet the NetSuite compliance standards including DKIM alignment. For more information about DKIM, see DomainKeys Identified Mail (DKIM).
Message-ID
Reason: See the following table for descriptions.

For information about how to optimize email campaign delivery, see the Five Golden Rules for Outbound Email in Email Best Practices.

The Reason, or root cause, of a specific error might indicate the following deliverability problems:

Reason (Errors)	Description
Not sent: Blocked by mail filter	The sending rate is not accurate or is too high (similar email messages are being sent too rapidly).
Not sent: Specific address(es) recently bounced	The email was not sent because the recipient address appears on the Bounced Email Addresses list.
Permanent Failure: Delivery not authorized, message refused	The sender is not authorized to send to the destination. This can be the result of per-host or per-recipient filtering.
Permanent Failure: No answer from host	The outbound connection attempt was not answered.
Permanent Failure: Bad destination mailbox address	The mailbox specified in the address does not exist.
Permanent Failure: Unable to route	The mail system was unable to determine the next hop for the message because the necessary routing information was unavailable from the directory server.
Permanent Failure: Mailbox disabled, not accepting messages	The mailbox exists, but is not accepting messages.
