I was pulling my hair out getting a response that looked like this.

HTTPRequestException: {"url": "https://us8.api.mailchimp.com/1.3/?method=ping", "status_code": 410, "reason": "Gone"}

I finally dug in and learned that they shutdown the api that is in use.

This isn't so much an issue but something that would be nice to see on the README file for this project :)
