I mailed a duplicate campaign. Why is the duplicate 100% missing?


A 250ok Inbox test could show as 100% missing if it is a duplicate of a previous send, even if the send if from a different address. To remedy this issue, 250ok recommends implementing an x-header or HTML body tag to help identify your mail. Click here for more information on adding an x-header to your inbox tests.
