Mail auto reply from list queston

Hello,
I very unexperinced with applescirpt i was try to get/write a script that will auto reply to an email in the Mail application with a preset number string off a list. Like sending serial numbers out to everyone who emails that address. The numbers can come from a text file or any other source on OS X or can even be built directly into the script if needs be. Anyone know of a script like this, i would be very grateful. Thanks in advance for any help.
