Keep in mind that gmail accounts have a 500 message per day sending limit (http://mail.google.com/support/bin/answer.py?hl=en&answer=22839 http://mail.google.com/support/bin/answer.py?hl=en&answe...). You can get around this by creating multiple accounts and cycling between them. Gmail will also disable your account if you have too many undeliverable messages, so be sure that you verify all email addresses before adding them to your list.
