Product Code as ID number on Low Inventory email

I would like to have my product code print on the email showing low inventory. The ID # was originally one that didn’t fit any of my products. My webmaster at that time eliminated the number that was there originally, but never determined how to insert my product number. Thank You for any help you can give me. (and could you make it very simple to understand as we are learning our cart.)

I have same problem as many of my items are 1 for stock and hated getting 100’s of low ivnentory emails.

What i did wasI set my Low stock notification threshold to -1 (negative one)

As i have inventory not to go below 0 . I now do not getting those emails.
