Monitoring delays in sending emails

We are using SAM 6.2.1

A part of our program being monitored compiles information and then sends emails with the collected information.  right now we are tracking the number of emails pending, but that has been less than completely useful.  I would lie to track how long it is taking for emails to process on average.  Now, I'll warn you, I am not that SQL literate.

Here is what we are using now:  EXEC sys_GetPerformanceCounterDataByName 'EmailProcessorPendingEmails'

Suggestions?
