sysmail_unsentitems (Transact-SQL)

Contains one row for each Database Mail message with the unsent or retrying status. Messages with unsent or retrying status are still in the mail queue and may be sent at any time. Messages can have the unsent status for the following reasons:

  • The message is new, and though the message has been placed on the mail queue, Database Mail is working on other messages and has not yet reached this message.
  • The Database Mail external program is not running and no mail is being sent.

Messages can have the retrying status for the following reasons:

  • Database Mail has attempted to send the mail, but the SMTP mail server could not be contacted. Database Mail will continue to attempt to send the message using other Database Mail accounts assigned to the profile that sent the message. If no accounts can send the mail, Database Mail will wait for the length of time configured for the Account Retry Delay parameter and then attempt to send the message again. Database Mail uses the Account Retry Attempts parameter to determine how many times to attempt to send the message. Messages retain retrying status as long as Database Mail is attempting to send the message.

Use this view when you want to see how many messages are waiting to be sent and how long they have been in the mail queue. Normally the number of unsent messages will be low. Conduct a benchmark test during normal operations to determine a reasonable number of messages in the message queue for your operations.

To see all messages processed by Database Mail, use sysmail_allitems (Transact-SQL). To see only messages with the failed status, use sysmail_faileditems (Transact-SQL). To see only messages that were sent, use sysmail_sentitems (Transact-SQL).

When troubleshooting Database Mail, this view may help you identify the nature of the problem, by showing you the number of messages waiting to be sent, and the amount of time the messages have waited. If no messages are being sent, the Database Mail external program may not be running, or there may be a network problem preventing Database Mail from contacting the SMTP servers. If many of the unsent messages have the same profile_id, there may be a problem with the SMTP server. Consider adding additional accounts to the profile. If messages are being sent, but messages are spending too much time in the queue, SQL Server may need more resources to process the volume of messages you require.

Granted to sysadmin fixed server role and DatabaseMailUserRole database role. When executed by a member of the sysadmin fixed server role, this view shows all unsent or retrying messages. All other users only see the unsent or retrying messages that they submitted.
