I received the halfway through Founder's Campaign e-mail telling me I can still pre-order the 80HE, but I already pre-ordered it. Just thought it was weird to receive a generic e-mail like that. I think you should take note of who has bought it and cross-check before sending the e-mails out, then you can not send them that e-mail. That way, in the future, if there is a product a customer hasn't pre-ordered but is available on kickstarter/launch, then that customer gets a potentially informative e-mail.
