MailChimp are just spam enablers. The vast majority of e-mail I get from them is to e-mail addresses that definitely never ever signed up for anything. They claim they use double opt in, but that's just a damn dirty lie.
Furthermore, they are past masters at helping their spammers craft their spam to defeat SpamAssassin and baysian filters, so the spam that actually makes it to my inbox is disproportionately from them. It's got so bad that I've got special mail server rules that focus on just them.
