When you are doing many model runs, it makes life easier to know if the modelrun is complete.  The code is below.

SENDMAIL,
SMTPSERVER='MAILSERVER HERE',
FROM='from@somwehere.com',
TO='to@somewhere.com',
SUBJECT='Subject Line Here',
MESSAGE='Message Goes Here',
USERNAME='username',
PASSWORD='password'

The things you replace here are pretty obvious.  If you have questions about the SMTPSERVER parameter, ask your IT person.  Also, for Windows domains, the USERNAME parameter should be ‘DOMAIN\USERNAME’ (you may be able to use your email address, depending on your email setup).
