        Greetings fellow gug,

        In anticipation of our upcoming Christmas party, December 29th - we are sending out a 'Secret Santa' list. You are receiving this email because you did not opt out of the Secret Santa activities.
        If you would like to opt out, tell Rudy IMMEDIATELY. At the bottom of this email, you should see a name - if you don't, Alex is currently at his computer swearing profusely.
        The name at the bottom represents the person you should be buying a secret gift for.
        The spending limit is currently set at $20.00, if you go significantly below the limit you will look like Cam, and if you go over the limit you will look like a COMPLETE FOOL.
        Remember to get something soon as the date is only 18 days away (from the date this was sent).

        THE PERSON YOU WILL GIVE A GIFT TO IS: %s.""" % (key,email_target,item[key]))
        msg = 'Subject: {}\n\n{}'.format(subject, value)
        # Dispatch the reindeer
        mail.sendmail(userName,email_target,msg)
