A lot of people who are checking out MailChimp will call or email us and ask, "Can I use a purchased email list with MailChimp?"
So we created this: http://caniuseapurchasedemaillist.com/
If you run an abuse desk somewhere, and you’re tired of answering that stupid question over and over, feel free to link people to it. If you’re not sure why importing a purchased email list into a 3rd party ESP is a bad thing, then promptly turn off your computer and unplug it from the wall. Thanks.
