While reading on A.com you have mentioned that the open rate is
calculated at the point the images are downloaded.Reports on deliveries
Please, can you confirm if this is also applicable for email which is
only viewed in the preview pane of the ISP. E.g. Outlook and Hotmail
both have preview pane. Does Adobe Campaign class my previews (all
images have downloaded at this point) as an open or do I actually have
to double click and open the email to register as an Opener.
