# Lead email bounce handling

When an end user emails a location via our built-in Lead Generation forms, MetaLocator generates a record in the Leads database, and also (optionally) delivers that lead via email to the location email address.  If that email address is invalid, the message will bounce, possibly leaving the requesting customer wondering why nobody contacted them.

To address this issue we have introduced lead bounce tracking.  When a lead is delivered to an email address with a [hard bounce](http://whatis.techtarget.com/definition/hard-bounce), we update the lead with the "Action" and "Diagnostic Code" headers returned by the receiving email server, if they are available.

[Action codes are defined here.](https://www.metalocator.com/lead-bounce-status-codes/)

This looks like the following:

Despite the contents, you should review the email address on record for that location, and obtain updated email contact information.
