Create an email template (Attribute).
Add a serial tag insert.
Go back to attributes TAB in setup and find the serial join data you want to be included in the email, Select the email rules TAB and find the template you just created. That will then add the serial$ data from the simpl program fusion join (Custom join 50 and above) To the email that fusion sends.
If you are monitoring devices attached to the processor (IPID), I would use the fusion SSI Equipment Status module. Perhaps you have a reason for serial data in the email in which case as above.
