If you tried to log in to your MailChimp account, but got an Account Suspended message, it's most likely because you've done something to set off a red flag.

Why Accounts Get Suspended, MailChimp
###* What causes a Red Flag in MailChimp? *###
Using account information that appears fake or anonymous. For example, signing up as "John Doe" from "Nowhere, USA".
You signed up with an email account that's free. While this isn't a show stopper, signing up with a free webmail account combined with another issue could be a flag.
Your most recent campaign received spam complaints.
Your most recent campaign looked "spammy". MailChimp is always trying to prevent spam complaints.
You appear to be "cold calling" or sending to prospects who never gave you permission. MailChimp is a permission-based email marketing platform. If you would like to send cold prospects emails, you will need to use a different ESP.
Your website doesn't have an opt-in process anywhere. MailChimp looks for this information and will require proof as to where and how you got your list. MailChimp does not allow purchased email lists.
Your most recent campaign contains unacceptable content or something offensive. MailChimp is particular about email contents and may choose not to provide service if the content is offensive.
Something else looks too risky for comfort and MailChimp's team has to check it out.
If your MailChimp account has been suspended, it isn't always due to bad email list data. Make sure you contact MailChimp to see if you are able to be un-suspended.
Because MailChimp is a strict ESP - which is why they have great deliverability - we recommend taking advantage of Email Assurance to ensure you are always in compliance with MailChimp's standards.
