# Lead bounce status codes

When leads fail to delivery, MetaLocator captures the bounce and stores an enumerated value along with the lead in the action field .  The values are as follows:

* BOUNCE_TRANSIENT: Amazon SES received a general bounce. You may be able to successfully retry sending to that recipient in the future.
* BOUNCE_PERMANENT: Amazon SES received a permanent bounce. MetaLocator will remove the value in the location email field in this case and log the issue in the system log.
* BOUNCE_UNDETERMINED:  Amazon SES received a bounce, but the cause was undetermined.  No action is taken by MetaLocator in this case.

These values come directly from Amazon [as documented here.](http://docs.aws.amazon.com/ses/latest/DeveloperGuide/notification-contents.html#bounce-types)
