Mailchimp integration and Spam

[Megafry]

What are you trying to do?

Our queue is full of failed Mailchimp integration (~1256).
Can you add an option to stop the integration for the following errors:

• 400 - zozoripob634@gmail.com has signed up to a lot of lists very recently; we're not allowing more signups for now
• 400 - sample@email.tst looks fake or invalid, please enter a real email address.

}
