Auto Email Message Failures

An overview of why a message may have failed to send.
An example of a failed message

On occasion, you may see a notification that your message has failed to send. The primary cause of this is that an email address is incorrect (or in less cases no longer valid). Depending on the number of recipients, it can sometimes be difficult to isolate exactly which email address is causing trouble, but a quick review of logical addresses can often highlight an email address error quite quickly.
