Constant Contact noted that some emails that are viewed in the preview pane would not be counted as “Opened”. It would be nice to know how many in the Did Not Open category were actually viewed that way. Is there a way I can figure this out?
If the viewer enables images to be seen it will be counted.
By default its not counted unless the viewer adds you to their safe list or selects the option to enable the images.
Generally speaking the preview is NOT counted as a result of the beacon pixel not being called on.
