How do I use Mandrill if I already have a MailChimp account?

On May 11, 2016, Mandrill accounts that weren't linked to a MailChimp account were disabled and can no longer be accessed. All Mandrill accounts will be now be created and accessed through MailChimp.

If you already have a MailChimp account but do not have a Mandrill account, you can create a free trial Mandrill account as a MailChimp addon. Learn more.
