I call bullshit. A 1% unsub rate at MailChimp triggers a warning but not even a manual review, let alone "kicking you to the curb". You can see them talk about it more in the comments on this post:

I assure you that no bullshit was intended; the stuff in the comments directly contradicts both the account suspension emails received and the contents of the MailChimp FAQ.
A big part of the reason I posted this was to get more background information, and today you were that special someone.
And thanks, I feel special.
The FAQ pages in question are linked prominently in the article. They have an entire section on this topic.
And I checked the FAQ and didn't see anything about a 1% unsub rate resulting in account suspension or anything. Maybe I missed it? Care to point it out?
As for the 1% details... you missed them:

They are all over the MailChimp FAQs.
You seem kind of hostile towards me, and I'm honestly not sure why.
Therefore, the issue is that if you serve them anything more than a few months after you get their email address, they are much more likely to unsubscribe. And on those services, unsubscribes count against your standing.
