Outbound Email | Troubleshooting



Overview

The ServiceNow platform can automatically notify selected users via email of specific activities in the system, such as updates to incidents or change requests. By default, ServiceNow sends all outbound email notifications from the default email address of the instance. For organizations that need to send emails from specific email addresses, such as from multiple service desks, or want to send notifications in different languages, the platform supports the configuration of multiple outbound addresses and separate email addresses for responses. For more information, see Email and SMS Notifications in the ServiceNow product documentation. 

When an instance does not send emails, it is important to identify the root cause. This section describes the outbound email process and provides troubleshooting solutions for common issues.

Note: The troubleshooting steps on this page pertain to sub-production instances only. If you experience email notification issues on a production instance, submit an incident.

 

  1. Email notifications must be configured properly. To verify that the email notification system properties are configured properly, see Email and SMS notifications. If your instance sends messages from an SMTP server your company maintains (rather than a ServiceNow SMTP server), verify your instance connects to the proper SMTP server. For instructions, refer to Verifying the instance has the proper custom SMTP server settings
  2. An action, such as adding a comment to an incident or closing a problem, triggers the addition of an event to the event log. If there is no email record listed in the Outbox or Sent mailbox, see Verifying if email event is created in the Outbox.
  3. The events process job processes the events.
  4. If a particular action no longer produces a notification, review the notification record's conditions to determine if they are valid. For additional information, see Verifying the notification's record conditions have been met.
  5. The SMTP Sender and SMS Sender jobs transmit all processed requests to the mail server. The mail server sends the email message to the user. For information on troubleshooting outbound emails, refer to Outbound Email Troubleshooting.
  6. The email client receives the message. If the email is not received, see Obtaining the Message ID to troubleshoot the mail server.
