# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

# Use the Chilkat Email API to create or load an email.

# The From name/address don't need to be specified. 
# GMail will automatically use your Gmail address if the following 2 lines are omitted.
email.put_FromName("My Name")

# To add more recipients, make additional calls to AddTo or AddCC, one per recipient...
