Here's a minimal example:

import logging
from logging.handlers import SMTPHandler

if __name__ == "__main__":
    logging.basicConfig(level=logging.INFO)

    mail_handler = SMTPHandler(
        "smtp.example.com",
        "navigator@example.com",
        "captain.nemo@example.com",
        "fyi")
    mail_handler.setLevel(logging.CRITICAL)

    root = logging.getLogger()
    root.addHandler(mail_handler)

    # will print amessage
    root.warn("this is fishy") 

    # will print a message and send an email
    root.critical("giant squid sighted")
