Do You Have a Global Suppression List?

Mandrill automatically adds emails that have previously bounced, unsubscribed, or reported a message a spam to the Rejection Blacklist in your account, but you can also add addresses to the Rejection Blacklist manually. For example, a recipient may have contacted you directly and asked to be removed or you might want to test rejections using your own email address.

Custom rejections never expire and adding and removing custom rejections won't affect your account's reputation. Learn how to add an email address to the Rejection Blacklist in your account.
